I looked at the refresh issue a bit more and discovered that Samba

also doesn't switch to a registration if a refresh fails, instead the
name is removed! This makes it even more imortant that a Samba WINS
server accepts refresh requests as registration requests if the name
is not registered. I've gone ahead and implemented this.
