It may be a pain to configure all those clients, but it's certainly
worth it.  Take a look at Microsoft's documentation (in their resource
kits) on how various Windows versions do name resolution, and you'll
see what I mean.

I don't know if this needs to be said or not, but ...

IIRC, Chris' setup was to run Samba with security = domain, and
passing authentication to a Samba or Windows NT/2000 Server domain
controller.  (Or am I thinking of someone else? Sorry, I lost Chris'
orginal message already. :( )

If that is the case, then it's important to let the PDC handle
both domain master browser and local master browser tasks, and
not ever let any system steal either role away from it (or
else bad things can happen).

But if the Samba server in question is PDC, then definitely
have it take both roles:

	; act as the domain and local master browsers
	domain master = yes
	local master = yes
	preferred master = yes
	os level = 65

If there's no PDC, then have the Samba server just take
the local master browser role:

	local master = yes
	preferred master = yes
	os level = 65

I don't think this is Chris' problem, but wanted to say
it just in case.

Yep, then restart the Samba daemons.  It's really simple.
