-<title>Quick Cross Subnet Browsing / Cross Workgroup Browsing guide</title>
-
-<para>
-This document should be read in conjunction with Browsing and may
-be taken as the fast track guide to implementing browsing across subnets
-and / or across workgroups (or domains). WINS is the best tool for resolution
-of NetBIOS names to IP addesses. WINS is NOT involved in browse list handling
-except by way of name to address mapping.
-</para>
-
-<note><para>
-MS Windows 2000 and later can be configured to operate with NO NetBIOS 
-over TCP/IP. Samba-3 and later also supports this mode of operation.
-</para></note>

-<title>Discussion</title>
-
-<para>
-Firstly, all MS Windows networking is based on SMB (Server Message
-Block) based messaging. SMB messaging may be implemented using NetBIOS or 
-without NetBIOS. Samba implements NetBIOS by encapsulating it over TCP/IP.
-MS Windows products can do likewise. NetBIOS based networking uses broadcast
-messaging to affect browse list management. When running NetBIOS over
-TCP/IP this uses UDP based messaging. UDP messages can be broadcast or unicast.
-</para>
-
-<para>
-Normally, only unicast UDP messaging can be forwarded by routers. The
-<command>remote announce</command>
-parameter to smb.conf helps to project browse announcements
-to remote network segments via unicast UDP. Similarly, the 
-<command>remote browse sync</command> parameter of <filename>smb.conf</filename>
-implements browse list collation using unicast UDP.
-</para>
-
-<para>
-Secondly, in those networks where Samba is the only SMB server technology
-wherever possible &nmbd; should be configured on one (1) machine as the WINS
-server. This makes it easy to manage the browsing environment. If each network
-segment is configured with it's own Samba WINS server, then the only way to
-get cross segment browsing to work is by using the 
-<command>remote announce</command> and the <command>remote browse sync</command>
-parameters to your <filename>smb.conf</filename> file.
-</para>
-
-<para>
-If only one WINS server is used for an entire multi-segment network then
-the use of the <command>remote announce</command> and the 
-<command>remote browse sync</command> parameters should NOT be necessary.
-</para>
-
-<para>
-As of Samba 3 WINS replication is being worked on. The bulk of the code has
-been committed, but it still needs maturation.
-</para>
-
-<para>
-Right now samba WINS does not support MS-WINS replication. This means that
-when setting up Samba as a WINS server there must only be one &nmbd; configured
-as a WINS server on the network. Some sites have used multiple Samba WINS
-servers for redundancy (one server per subnet) and then used 
-<command>remote browse sync</command> and <command>remote announce</command>
-to affect browse list collation across all
-segments. Note that this means clients will only resolve local names,
-and must be configured to use DNS to resolve names on other subnets in
-order to resolve the IP addresses of the servers they can see on other
-subnets. This setup is not recommended, but is mentioned as a practical
-consideration (ie: an 'if all else fails' scenario).
-</para>
-
-<para>
-Lastly, take note that browse lists are a collection of unreliable broadcast
-messages that are repeated at intervals of not more than 15 minutes. This means
-that it will take time to establish a browse list and it can take up to 45
-minutes to stabilise, particularly across network segments.
-</para>

-<title>How browsing functions and how to deploy stable and 
-dependable browsing using Samba</title>
-
-
-<para>
-As stated above, MS Windows machines register their NetBIOS names 
-(i.e.: the machine name for each service type in operation) on start 
-up. Also, as stated above, the exact method by which this name registration 
-takes place is determined by whether or not the MS Windows client/server 
-has been given a WINS server address, whether or not LMHOSTS lookup 
-is enabled, or if DNS for NetBIOS name resolution is enabled, etc.
-</para>
-
-<para>
-In the case where there is no WINS server all name registrations as 
-well as name lookups are done by UDP broadcast. This isolates name 
-resolution to the local subnet, unless LMHOSTS is used to list all 
-names and IP addresses. In such situations Samba provides a means by 
-which the samba server name may be forcibly injected into the browse 
-list of a remote MS Windows network (using the 
-<command>remote announce</command> parameter).
-</para>
-
-<para>
-Where a WINS server is used, the MS Windows client will use UDP 
-unicast to register with the WINS server. Such packets can be routed 
-and thus WINS allows name resolution to function across routed networks.
-</para>
-
-<para>
-During the startup process an election will take place to create a 
-local master browser if one does not already exist. On each NetBIOS network 
-one machine will be elected to function as the domain master browser. This 
-domain browsing has nothing to do with MS security domain control. 
-Instead, the domain master browser serves the role of contacting each local 
-master browser (found by asking WINS or from LMHOSTS) and exchanging browse 
-list contents. This way every master browser will eventually obtain a complete 
-list of all machines that are on the network. Every 11-15 minutes an election 
-is held to determine which machine will be the master browser. By the nature of 
-the election criteria used, the machine with the highest uptime, or the 
-most senior protocol version, or other criteria, will win the election 
-as domain master browser.
-</para>
-
-<para>
-Clients wishing to browse the network make use of this list, but also depend 
-on the availability of correct name resolution to the respective IP 
-address/addresses. 
-</para>
-
-<para>
-Any configuration that breaks name resolution and/or browsing intrinsics 
-will annoy users because they will have to put up with protracted 
-inability to use the network services.
-</para>
-
-<para>
-Samba supports a feature that allows forced synchonisation 
-of browse lists across routed networks using the <command>remote 
-browse sync</command> parameter in the <filename>smb.conf</filename> file. 
-This causes Samba to contact the local master browser on a remote network and 
-to request browse list synchronisation. This effectively bridges 
-two networks that are separated by routers. The two remote 
-networks may use either broadcast based name resolution or WINS 
-based name resolution, but it should be noted that the <command>remote 
-browse sync</command> parameter provides browse list synchronisation - and 
-that is distinct from name to address resolution, in other 
-words, for cross subnet browsing to function correctly it is 
-essential that a name to address resolution mechanism be provided. 
-This mechanism could be via DNS, <filename>/etc/hosts</filename>, 
-and so on.

-<title>Use of the <command>Remote Announce</command> parameter</title>
-<para>
-The <command>remote announce</command> parameter of 
-<filename>smb.conf</filename> can be used to forcibly ensure
-that all the NetBIOS names on a network get announced to a remote network.
-The syntax of the <command>remote announce</command> parameter is:
-<programlisting>
-	remote announce = <replaceable>a.b.c.d [e.f.g.h]</replaceable> ...
-</programlisting>
-_or_
-<programlisting>
-	remote announce = <replaceable>a.b.c.d/WORKGROUP [e.f.g.h/WORKGROUP]</replaceable> ...
-</programlisting>
-
-where:
-<variablelist>
-<varlistentry><term><replaceable>a.b.c.d</replaceable> and 
-<replaceable>e.f.g.h</replaceable></term>
-<listitem><para>is either the LMB (Local Master Browser) IP address
-or the broadcst address of the remote network.
-ie: the LMB is at 192.168.1.10, or the address
-could be given as 192.168.1.255 where the netmask
-is assumed to be 24 bits (255.255.255.0).
-When the remote announcement is made to the broadcast
-address of the remote network every host will receive
-our announcements. This is noisy and therefore
-undesirable but may be necessary if we do NOT know
-the IP address of the remote LMB.</para></listitem>
-</varlistentry>
-
-<varlistentry>
-<term><replaceable>WORKGROUP</replaceable></term>
-<listitem><para>is optional and can be either our own workgroup
-or that of the remote network. If you use the
-workgroup name of the remote network then our
-NetBIOS machine names will end up looking like
-they belong to that workgroup, this may cause
-name resolution problems and should be avoided.

-<title>Use of the <command>Remote Browse Sync</command> parameter</title>
-
-<para>
-The <command>remote browse sync</command> parameter of 
-<filename>smb.conf</filename> is used to announce to
-another LMB that it must synchronise it's NetBIOS name list with our
-Samba LMB. It works ONLY if the Samba server that has this option is
-simultaneously the LMB on it's network segment.
-</para>
-
-<para>
-The syntax of the <command>remote browse sync</command> parameter is:
-
-<programlisting>
-remote browse sync = <replaceable>a.b.c.d</replaceable>
-</programlisting>
-
-where <replaceable>a.b.c.d</replaceable> is either the IP address of the remote LMB or else is the network broadcast address of the remote segment.
-</para>
-
-</sect1>

-<sect1>
-<title>Use of WINS</title>
-
-<para>
-Use of WINS (either Samba WINS _or_ MS Windows NT Server WINS) is highly
-recommended. Every NetBIOS machine registers it's name together with a
-name_type value for each of of several types of service it has available.
-eg: It registers it's name directly as a unique (the type 0x03) name.
-It also registers it's name if it is running the lanmanager compatible
-server service (used to make shares and printers available to other users)
-by registering the server (the type 0x20) name.
-</para>
-
-<para>
-All NetBIOS names are up to 15 characters in length. The name_type variable
-is added to the end of the name - thus creating a 16 character name. Any
-name that is shorter than 15 characters is padded with spaces to the 15th
-character. ie: All NetBIOS names are 16 characters long (including the
-name_type information).
-</para>
-
-<para>
-WINS can store these 16 character names as they get registered. A client
-that wants to log onto the network can ask the WINS server for a list
-of all names that have registered the NetLogon service name_type. This saves
-broadcast traffic and greatly expedites logon processing. Since broadcast
-name resolution can not be used across network segments this type of
-information can only be provided via WINS _or_ via statically configured
-<filename>lmhosts</filename> files that must reside on all clients in the
-absence of WINS.
-</para>
-
-<para>
-WINS also serves the purpose of forcing browse list synchronisation by all
-LMB's. LMB's must synchronise their browse list with the DMB (domain master
-browser) and WINS helps the LMB to identify it's DMB. By definition this
-will work only within a single workgroup. Note that the domain master browser
-has NOTHING to do with what is referred to as an MS Windows NT Domain. The
-later is a reference to a security environment while the DMB refers to the
-master controller for browse list information only.
-</para>
-
-<para>
-Use of WINS will work correctly only if EVERY client TCP/IP protocol stack
-has been configured to use the WINS server/s. Any client that has not been
-configured to use the WINS server will continue to use only broadcast based
-name registration so that WINS may NEVER get to know about it. In any case,
-machines that have not registered with a WINS server will fail name to address
-lookup attempts by other clients and will therefore cause workstation access
-errors.
-</para>
-
-<para>
-To configure Samba as a WINS server just add 
-<command>wins support = yes</command> to the <filename>smb.conf</filename>
-file [globals] section.
-</para>
-
-<para>
-To configure Samba to register with a WINS server just add
-"wins server = a.b.c.d" to your smb.conf file [globals] section.
-</para>
-
-<important><para>
-Never use both <command>wins support = yes</command> together
-with <command>wins server = a.b.c.d</command>
-particularly not using it's own IP address.
-Specifying both will cause &nmbd; to refuse to start!

-<title>Do NOT use more than one (1) protocol on MS Windows machines</title>
-
-<para>
-A very common cause of browsing problems results from installing more than
-one protocol on an MS Windows machine.
-</para>
-
-<para>
-Every NetBIOS machine takes part in a process of electing the LMB (and DMB)
-every 15 minutes. A set of election criteria is used to determine the order
-of precidence for winning this election process. A machine running Samba or
-Windows NT will be biased so that the most suitable machine will predictably
-win and thus retain it's role.
-</para>
-
-<para>
-The election process is "fought out" so to speak over every NetBIOS network
-interface. In the case of a Windows 9x machine that has both TCP/IP and IPX
-installed and has NetBIOS enabled over both protocols the election will be
-decided over both protocols. As often happens, if the Windows 9x machine is
-the only one with both protocols then the LMB may be won on the NetBIOS
-interface over the IPX protocol. Samba will then lose the LMB role as Windows
-9x will insist it knows who the LMB is. Samba will then cease to function
-as an LMB and thus browse list operation on all TCP/IP only machines will
-fail.
-</para>
-
-<para><emphasis>
-Windows 95, 98, 98se, Me are referred to generically as Windows 9x.
-The Windows NT4, 2000, XP and 2003 use common protocols. These are roughly
-referred to as the WinNT family, but it should be recognised that 2000 and
-XP/2003 introduce new protocol extensions that cause them to behave 
-differently from MS Windows NT4. Generally, where a server does NOT support
-the newer or extended protocol, these will fall back to the NT4 protocols.
-</emphasis></para>
-
-<para>
-The safest rule of all to follow it this - USE ONLY ONE PROTOCOL!

-<title>Name Resolution Order</title>
-
-<para>
-Resolution of NetBIOS names to IP addresses can take place using a number
-of methods. The only ones that can provide NetBIOS name_type information
-are:</para>
-
-<simplelist>
-<member>WINS: the best tool!</member>
-<member>LMHOSTS: is static and hard to maintain.</member>
-<member>Broadcast: uses UDP and can not resolve names across remote segments.</member>
-</simplelist>
-
-<para>
-Alternative means of name resolution includes:</para>
-<simplelist>
-<member>/etc/hosts: is static, hard to maintain, and lacks name_type info</member>
-<member>DNS: is a good choice but lacks essential name_type info.</member>
-</simplelist>
-
-<para>
-Many sites want to restrict DNS lookups and want to avoid broadcast name
-resolution traffic. The "name resolve order" parameter is of great help here.
-The syntax of the "name resolve order" parameter is:
-<programlisting>
-name resolve order = wins lmhosts bcast host
-</programlisting>
-_or_
-<programlisting>
-name resolve order = wins lmhosts  	(eliminates bcast and host)
-</programlisting>
-The default is:
-<programlisting>
-name  resolve order = host lmhost wins bcast
-</programlisting>.
-where "host" refers the the native methods used by the Unix system
-to implement the gethostbyname() function call. This is normally
-controlled by <filename>/etc/host.conf</filename>, <filename>/etc/nsswitch.conf</filename> and <filename>/etc/resolv.conf</filename>.

-<title>Improved browsing in samba</title>
-
-<sect1>
-<title>Overview of browsing</title>
-
-<para>
-SMB networking provides a mechanism by which clients can access a list
-of machines in a network, a so-called <command>browse list</command>.  This list
-contains machines that are ready to offer file and/or print services
-to other machines within the network. Thus it does not include
-machines which aren't currently able to do server tasks.  The browse
-list is heavily used by all SMB clients.  Configuration of SMB
-browsing has been problematic for some Samba users, hence this
-document.
-</para>
-
-<para>
-MS Windows 2000 and later, as with Samba 3 and later, can be
-configured to not use NetBIOS over TCP/IP. When configured this way
-it is imperative that name resolution (using DNS/LDAP/ADS) be correctly
-configured and operative. Browsing will NOT work if name resolution
-from SMB machine names to IP addresses does not function correctly.
-</para>
-
-<para>
-Where NetBIOS over TCP/IP is enabled use of a WINS server is highly
-recommended to aid the resolution of NetBIOS (SMB) names to IP addresses.
-WINS allows remote segment clients to obtain NetBIOS name_type information
-that can NOT be provided by any other means of name resolution.
-</para>
-
-</sect1>

-<sect1>
-<title>Browsing support in samba</title>
-
-<para>
-Samba facilitates browsing.  The browsing is supported by &nmbd;
-and is also controlled by options in the &smb.conf; file.
-Samba can act as a local browse master for a workgroup and the ability
-for samba to support domain logons and scripts is now available.
-</para>
-
-<para>
-Samba can also act as a domain master browser for a workgroup.  This
-means that it will collate lists from local browse masters into a
-wide area network server list.  In order for browse clients to
-resolve the names they may find in this list, it is recommended that
-both samba and your clients use a WINS server.
-</para>
-
-<para>
-Note that you should NOT set Samba to be the domain master for a
-workgroup that has the same name as an NT Domain: on each wide area
-network, you must only ever have one domain master browser per workgroup,
-regardless of whether it is NT, Samba or any other type of domain master
-that is providing this service.
-</para>
-
-<note><para>
-Nmbd can be configured as a WINS server, but it is not
-necessary to specifically use samba as your WINS server.  MS Windows
-NT4, Server or Advanced Server 2000 or 2003 can be configured as
-your WINS server.  In a mixed NT/2000/2003 server and samba environment on
-a Wide Area Network, it is recommended that you use the Microsoft
-WINS server capabilities.  In a samba-only environment, it is
-recommended that you use one and only one Samba server as your WINS server.
-</para></note>
-
-<para>
-To get browsing to work you need to run nmbd as usual, but will need
-to use the <command>workgroup</command> option in &smb.conf;
-to control what workgroup Samba becomes a part of.
-</para>
-
-<para>
-Samba also has a useful option for a Samba server to offer itself for
-browsing on another subnet.  It is recommended that this option is only
-used for 'unusual' purposes: announcements over the internet, for
-example.  See <command>remote announce</command> in the 
-&smb.conf; man page.  
-</para>
-</sect1>
-
-<sect1>
-<title>Problem resolution</title>
-
-<para>
-If something doesn't work then hopefully the log.nmb file will help
-you track down the problem.  Try a debug level of 2 or 3 for finding
-problems. Also note that the current browse list usually gets stored
-in text form in a file called <filename>browse.dat</filename>.
-</para>
-
-<para>
-Note that if it doesn't work for you, then you should still be able to
-type the server name as <filename>\\SERVER</filename> in filemanager then
-hit enter and filemanager should display the list of available shares.
-</para>
-
-<para>
-Some people find browsing fails because they don't have the global
-<command>guest account</command> set to a valid account.  Remember that the
-IPC$ connection that lists the shares is done as guest, and thus you must
-have a valid guest account.
-</para>
-
-<para><emphasis>
-MS Windows 2000 and upwards (as with Samba) can be configured to disallow
-anonymous (ie: Guest account) access to the IPC$ share. In that case, the
-MS Windows 2000/XP/2003 machine acting as an SMB/CIFS client will use the
-name of the currently logged in user to query the IPC$ share. MS Windows
-9X clients are not able to do this and thus will NOT be able to browse
-server resources.
-</emphasis></para>
-
-<para>
-The other big problem people have is that their broadcast address,
-netmask or IP address is wrong (specified with the "interfaces" option
-in &smb.conf;)
-</para>
-</sect1>
-
-<sect1>
-<title>Browsing across subnets</title>
-<para>
-Since the release of Samba 1.9.17(alpha1) Samba has been
-updated to enable it to support the replication of browse lists
-across subnet boundaries.  New code and options have been added to
-achieve this.  This section describes how to set this feature up
-in different settings.
-</para>
-
-<para>
-To see browse lists that span TCP/IP subnets (ie.  networks separated
-by routers that don't pass broadcast traffic) you must set up at least
-one WINS server.  The WINS server acts as a DNS for NetBIOS names, allowing
-NetBIOS name to IP address translation to be done by doing a direct
-query of the WINS server.  This is done via a directed UDP packet on
-port 137 to the WINS server machine.  The reason for a WINS server is
-that by default, all NetBIOS name to IP address translation is done
-by broadcasts from the querying machine.  This means that machines
-on one subnet will not be able to resolve the names of machines on
-another subnet without using a WINS server.
-</para>
-
-<para>
-Remember, for browsing across subnets to work correctly, all machines,
-be they Windows 95, Windows NT, or Samba servers must have the IP address
-of a WINS server given to them by a DHCP server, or by manual configuration 
-(for Win95 and WinNT, this is in the TCP/IP Properties, under Network 
-settings) for Samba this is in the &smb.conf; file.
-</para>
-
-<sect2>
-<title>How does cross subnet browsing work ?</title>
-
-<para>
-Cross subnet browsing is a complicated dance, containing multiple
-moving parts.  It has taken Microsoft several years to get the code
-that achieves this correct, and Samba lags behind in some areas.
-Samba is capable of cross subnet browsing when configured correctly.
-</para>

-Consider a network set up as follows :

-<para>
-Consisting of 3 subnets (1, 2, 3) connected by two routers
-(R1, R2) - these do not pass broadcasts.  Subnet 1 has 5 machines
-on it, subnet 2 has 4 machines, subnet 3 has 4 machines.  Assume
-for the moment that all these machines are configured to be in the
-same workgroup (for simplicities sake).  Machine N1_C on subnet 1
-is configured as Domain Master Browser (ie.  it will collate the
-browse lists for the workgroup).  Machine N2_D is configured as
-WINS server and all the other machines are configured to register
-their NetBIOS names with it.
-</para>
-
-<para>
-As all these machines are booted up, elections for master browsers
-will take place on each of the three subnets.  Assume that machine
-N1_C wins on subnet 1, N2_B wins on subnet 2, and N3_D wins on

-On each of the three networks, machines that are configured to

-these services.  The local master browser on each subnet will
-receive these broadcasts and keep a record of the fact that

-will be on the browse list.

-<para>
-For each network, the local master browser on that network is
-considered 'authoritative' for all the names it receives via
-local broadcast.  This is because a machine seen by the local
-master browser via a local broadcast must be on the same 
-network as the local master browser and thus is a 'trusted'
-and 'verifiable' resource.  Machines on other networks that
-the local master browsers learn about when collating their

-<title>Setting up a WINS server</title>

-<para>
-Either a Samba machine or a Windows NT Server machine may be set up
-as a WINS server.  To set a Samba machine to be a WINS server you must
-add the following option to the &smb.conf; file on the selected machine :
-in the [globals] section add the line 
-</para>
-
-<para>
-<command>		wins support = yes</command>
-</para>
-
-<para>
-Versions of Samba prior to 1.9.17 had this parameter default to
-yes.  If you have any older versions of Samba on your network it is
-strongly suggested you upgrade to a recent version, or at the very
-least set the parameter to 'no' on all these machines.
-</para>
-
-<para>
-Machines with <command>wins support = yes</command> will keep a list of 
-all NetBIOS names registered with them, acting as a DNS for NetBIOS names.

-You should set up only ONE wins server.  Do NOT set the
-<command>wins support = yes</command> option on more than one Samba 
-server.
-</para>
-
-<para>
-To set up a Windows NT Server as a WINS server you need to set up
-the WINS service - see your NT documentation for details.  Note that
-Windows NT WINS Servers can replicate to each other, allowing more
-than one to be set up in a complex subnet environment.  As Microsoft
-refuse to document these replication protocols Samba cannot currently
-participate in these replications.  It is possible in the future that
-a Samba->Samba WINS replication protocol may be defined, in which
-case more than one Samba machine could be set up as a WINS server
-but currently only one Samba server should have the 
-<command>wins support = yes</command> parameter set.
-</para>
-
-<para>
-After the WINS server has been configured you must ensure that all
-machines participating on the network are configured with the address
-of this WINS server.  If your WINS server is a Samba machine, fill in
-the Samba machine IP address in the "Primary WINS Server" field of
-the "Control Panel->Network->Protocols->TCP->WINS Server" dialogs
-in Windows 95 or Windows NT.  To tell a Samba server the IP address
-of the WINS server add the following line to the [global] section of
-all &smb.conf; files :
-</para>
-
-<para>
-<command>wins server = &gt;name or IP address&lt;</command>
-</para>
-
-<para>
-where &gt;name or IP address&lt; is either the DNS name of the WINS server
-machine or its IP address.
-</para>
-
-<para>
-Note that this line MUST NOT BE SET in the &smb.conf; file of the Samba
-server acting as the WINS server itself.  If you set both the
-<command>wins support = yes</command> option and the 
-<command>wins server = &lt;name&gt;</command> option then
-nmbd will fail to start.

-<title>Setting up Browsing in a WORKGROUP</title>
-
-<para>
-To set up cross subnet browsing on a network containing machines
-in up to be in a WORKGROUP, not an NT Domain you need to set up one
-Samba server to be the Domain Master Browser (note that this is *NOT*
-the same as a Primary Domain Controller, although in an NT Domain the
-same machine plays both roles).  The role of a Domain master browser is
-to collate the browse lists from local master browsers on all the
-subnets that have a machine participating in the workgroup.  Without
-one machine configured as a domain master browser each subnet would
-be an isolated workgroup, unable to see any machines on any other
-subnet.  It is the presense of a domain master browser that makes
-cross subnet browsing possible for a workgroup.
-</para>
-
-<para>
-In an WORKGROUP environment the domain master browser must be a
-Samba server, and there must only be one domain master browser per
-workgroup name.  To set up a Samba server as a domain master browser,
-set the following option in the [global] section of the &smb.conf; file :
-</para>
-
-<para>
-<command>domain master = yes</command>
-</para>
-
-<para>
-The domain master browser should also preferrably be the local master
-browser for its own subnet.  In order to achieve this set the following
-options in the [global] section of the &smb.conf; file :

-domain master = yes
-local master = yes
-preferred master = yes

-</para>
-

-The domain master browser may be the same machine as the WINS
-server, if you require.
-</para>
-
-<para>
-Next, you should ensure that each of the subnets contains a
-machine that can act as a local master browser for the
-workgroup.  Any MS Windows NT/2K/XP/2003  machine should be
-able to do this, as will Windows 9x machines (although these
-tend to get rebooted more often, so it's not such a good idea
-to use these).  To make a Samba server a local master browser
-set the following options in the [global] section of the
