Before reproduction -of posted information effort has been made to validate the information provided. -Where additional information was uncovered through this validation it is provided -also. -</p><div class="sect1" lang="en"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id2982185"></a>Features and Benefits</h2></div></div><div></div></div><p> -When MS Windows NT3.5 was introduced the hot new topic was the ability to implement -Group Policies for users and group. Then along came MS Windows NT4 and a few sites -started to adopt this capability. How do we know that? By way of the number of "booboos" -(or mistakes) administrators made and then requested help to resolve. -</p><p> -By the time that MS Windows 2000 and Active Directory was released, administrators -got the message: Group Policies are a good thing! They can help reduce administrative -costs and actually can help to create happier users. But adoption of the true -potential of MS Windows 200x Active Directory and Group Policy Objects (GPOs) for users -and machines were picked up on rather slowly. This was very obvious from the samba -mailing list as in 2000 and 2001 there were very few postings regarding GPOs and -how to replicate them in a Samba environment. -</p><p> -Judging by the traffic volume since mid 2002, GPOs have become a standard part of -the deployment in many sites. This chapter reviews techniques and methods that can -be used to exploit opportunities for automation of control over user desktops and -network client workstations. -</p><p> -A tool new to Samba-3 may become an important part of the future Samba Administrators' -arsenal. The <b class="command">editreg</b> tool is described in this document. -</p></div><div class="sect1" lang="en"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id2982237"></a>Creating and Managing System Policies</h2></div></div><div></div></div><p> -Under MS Windows platforms, particularly those following the release of MS Windows -NT4 and MS Windows 95) it is possible to create a type of file that would be placed -in the NETLOGON share of a domain controller. As the client logs onto the network -this file is read and the contents initiate changes to the registry of the client -machine. This file allows changes to be made to those parts of the registry that -affect users, groups of users, or machines. -</p><p> -For MS Windows 9x/Me this file must be called <tt class="filename">Config.POL</tt> and may -be generated using a tool called <tt class="filename">poledit.exe</tt>, better known as the -Policy Editor. The policy editor was provided on the Windows 98 installation CD, but -disappeared again with the introduction of MS Windows Me (Millennium Edition). From -comments from MS Windows network administrators it would appear that this tool became -a part of the MS Windows Me Resource Kit. -</p><p> -MS Windows NT4 Server products include the <span class="emphasis"><em>System Policy Editor</em></span> -under the <tt class="filename">Start -> Programs -> Administrative Tools</tt> menu item. -For MS Windows NT4 and later clients this file must be called <tt class="filename">NTConfig.POL</tt>. -</p><p> -New with the introduction of MS Windows 2000 was the Microsoft Management Console -or MMC. This tool is the new wave in the ever changing landscape of Microsoft -methods for management of network access and security. Every new Microsoft product -or technology seems to obsolete the old rules and to introduce newer and more -complex tools and methods. To Microsoft's credit though, the MMC does appear to -be a step forward, but improved functionality comes at a great price. -</p><p> -Before embarking on the configuration of network and system policies it is highly -advisable to read the documentation available from Microsoft's web site regarding -<a href="http://www.microsoft.com/ntserver/management/deployment/planguide/prof_policies.asp" target="_top"> -Implementing Profiles and Policies in Windows NT 4.0 from http://www.microsoft.com/ntserver/management/deployment/planguide/prof_policies.asp</a> available from Microsoft. -There are a large number of documents in addition to this old one that should also -be read and understood. Try searching on the Microsoft web site for "Group Policies". -</p><p> -What follows is a very brief discussion with some helpful notes. The information provided -here is incomplete - you are warned. -</p><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="id2982348"></a>Windows 9x/Me Policies</h3></div></div><div></div></div><p> - You need the Win98 Group Policy Editor to set Group Profiles up under Windows 9x/Me. - It can be found on the Original full product Win98 installation CD under - <tt class="filename">tools/reskit/netadmin/poledit</tt>. Install this using the - Add/Remove Programs facility and then click on the 'Have Disk' tab. - </p><p> - Use the Group Policy Editor to create a policy file that specifies the location of - user profiles and/or the <tt class="filename">My Documents</tt> etc. Then save these - settings in a file called <tt class="filename">Config.POL</tt> that needs to be placed in the - root of the <i class="parameter"><tt>[NETLOGON]</tt></i> share. If Win98 is configured to log onto - the Samba Domain, it will automatically read this file and update the Win9x/Me registry - of the machine as it logs on. - </p><p> - Further details are covered in the Win98 Resource Kit documentation. - </p><p> - If you do not take the right steps, then every so often Win9x/Me will check the - integrity of the registry and will restore it's settings from the back-up - copy of the registry it stores on each Win9x/Me machine. Hence, you will - occasionally notice things changing back to the original settings. - </p><p> - Install the group policy handler for Win9x to pick up group policies. Look on the - Win98 CD in <tt class="filename">\tools\reskit\netadmin\poledit</tt>. - Install group policies on a Win9x client by double-clicking - <tt class="filename">grouppol.inf</tt>. Log off and on again a couple of times and see - if Win98 picks up group policies. Unfortunately this needs to be done on every - Win9x/Me machine that uses group policies. - </p></div><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="id2981896"></a>Windows NT4 Style Policy Files</h3></div></div><div></div></div><p> - To create or edit <tt class="filename">ntconfig.pol</tt> you must use the NT Server - Policy Editor, <b class="command">poledit.exe</b> which is included with NT4 Server - but <span class="emphasis"><em>not NT Workstation</em></span>. There is a Policy Editor on a NT4 - Workstation but it is not suitable for creating <span class="emphasis"><em>Domain Policies</em></span>. - Further, although the Windows 95 Policy Editor can be installed on an NT4 - Workstation/Server, it will not work with NT clients. However, the files from - the NT Server will run happily enough on an NT4 Workstation. - </p><p> - You need <tt class="filename">poledit.exe</tt>, <tt class="filename">common.adm</tt> and <tt class="filename">winnt.adm</tt>. - It is convenient to put the two *.adm files in the <tt class="filename">c:\winnt\inf</tt> - directory which is where the binary will look for them unless told otherwise. Note also that that - directory is normally 'hidden'. - </p><p> - The Windows NT policy editor is also included with the Service Pack 3 (and - later) for Windows NT 4.0. Extract the files using <b class="command">servicepackname /x</b>, - i.e. that's <b class="command">Nt4sp6ai.exe /x</b> for service pack 6a. The policy editor, - <b class="command">poledit.exe</b> and the associated template files (*.adm) should - be extracted as well. It is also possible to downloaded the policy template - files for Office97 and get a copy of the policy editor. Another possible - location is with the Zero Administration Kit available for download from Microsoft. - </p><div class="sect3" lang="en"><div class="titlepage"><div><div><h4 class="title"><a name="id2982006"></a>Registry Spoiling</h4></div></div><div></div></div><p> - With NT4 style registry based policy changes, a large number of settings are not - automatically reversed as the user logs off. Since the settings that were in the - NTConfig.POL file were applied to the client machine registry and that apply to the - hive key HKEY_LOCAL_MACHINE are permanent until explicitly reversed. This is known - as tattooing. It can have serious consequences down-stream and the administrator must - be extremely careful not to lock out the ability to manage the machine at a later date. - </p></div></div><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="id2982030"></a>MS Windows 200x / XP Professional Policies</h3></div></div><div></div></div><p> - Windows NT4 System policies allows setting of registry parameters specific to - users, groups and computers (client workstations) that are members of the NT4 - style domain. Such policy file will work with MS Windows 2000 / XP clients also. - </p><p> - New to MS Windows 2000 Microsoft introduced a new style of group policy that confers - a superset of capabilities compared with NT4 style policies. Obviously, the tool used - to create them is different, and the mechanism for implementing them is much changed. - </p><p> - The older NT4 style registry based policies are known as <span class="emphasis"><em>Administrative Templates</em></span> - in MS Windows 2000/XP Group Policy Objects (GPOs). The later includes ability to set various security - configurations, enforce Internet Explorer browser settings, change and redirect aspects of the - users' desktop (including: the location of <tt class="filename">My Documents</tt> files (directory), as - well as intrinsics of where menu items will appear in the Start menu). An additional new - feature is the ability to make available particular software Windows applications to particular - users and/or groups. - </p><p> - Remember: NT4 policy files are named <tt class="filename">NTConfig.POL</tt> and are stored in the root - of the NETLOGON share on the domain controllers. A Windows NT4 user enters a username, a password - and selects the domain name to which the logon will attempt to take place. During the logon - process the client machine reads the NTConfig.POL file from the NETLOGON share on the authenticating - server, modifies the local registry values according to the settings in this file. - </p><p> - Windows 2K GPOs are very feature rich. They are NOT stored in the NETLOGON share, rather part of - a Windows 200x policy file is stored in the Active Directory itself and the other part is stored - in a shared (and replicated) volume called the SYSVOL folder. This folder is present on all Active - Directory domain controllers. The part that is stored in the Active Directory itself is called the - group policy container (GPC), and the part that is stored in the replicated share called SYSVOL is - known as the group policy template (GPT). - </p><p> - With NT4 clients the policy file is read and executed upon only as each user logs onto the network. - MS Windows 200x policies are much more complex - GPOs are processed and applied at client machine - startup (machine specific part) and when the user logs onto the network the user specific part - is applied. In MS Windows 200x style policy management each machine and/or user may be subject - to any number of concurrently applicable (and applied) policy sets (GPOs). Active Directory allows - the administrator to also set filters over the policy settings. No such equivalent capability - exists with NT4 style policy files. - </p><div class="sect3" lang="en"><div class="titlepage"><div><div><h4 class="title"><a name="id2982130"></a>Administration of Win2K / XP Policies</h4></div></div><div></div></div><p> - Instead of using the tool called <span class="application">The System Policy Editor</span>, commonly called Poledit (from the - executable name <b class="command">poledit.exe</b>), <span class="acronym">GPOs</span> are created and managed using a - <span class="application">Microsoft Management Console</span> <span class="acronym">(MMC)</span> snap-in as follows:</p><div class="procedure"><ol type="1"><li><p> - Go to the Windows 200x / XP menu <span class="guimenu">Start->Programs->Administrative Tools</span> - and select the MMC snap-in called <span class="guimenuitem">Active Directory Users and Computers</span> - </p></li><li><p> - Select the domain or organizational unit (OU) that you wish to manage, then right click - to open the context menu for that object, select the properties item. - </p></li><li><p> - Now left click on the <span class="guilabel">Group Policy</span> tab, then left click on the New tab.

These files have a .adm extension, both in NT4 as well as in Windows 200x / XP. - Beware however, since the .adm files are NOT interchangeable across NT4 and Windows 200x. - The later introduces many new features as well as extended definition capabilities. It is - well beyond the scope of this documentation to explain how to program .adm files, for that - the administrator is referred to the Microsoft Windows Resource Kit for your particular - version of MS Windows. - </p><div class="note" style="margin-left: 0.5in; margin-right: 0.5in;"><h3 class="title">Note</h3><p> - The MS Windows 2000 Resource Kit contains a tool called gpolmig.exe.

As system administrator, you have the option of renaming the -policy file and, by modifying the Windows NT-based workstation, directing the computer to update -the policy from a manual path. You can do this by either manually changing the registry or by using -the System Policy Editor. This path can even be a local path such that each machine has its own policy file, -but if a change is necessary to all machines, this change must be made individually to each workstation. -</p><p> -When a Windows NT4/200x/XP machine logs onto the network the NETLOGON share on the authenticating domain -controller for the presence of the NTConfig.POL file.
