samba - Feb 2003 - Help Active Directory client trying to connect to Samba Server

I've got a laptop from work running Windows 2000 Professional.  My
office just converted over to active directory and I can no longer use
my laptop at home to connect to my Samba server.

I'm running Samba on two machines, one at version 2.0.10-0.7 and the
other at 2.2.5-1.  Until active directory was installed at work I had no
problem connecting my laptop to either server for both disk shares and
most importantly printer shares.  On the two samba servers I'm running
SHARE level security and allowing GUEST users.  As I said this worked
fine until my office installed Active Directory.

Now whenever I try to connect to one of my Samba servers from my laptop
I receive the Error Message "\\machinename not accessible" 
"There are
currently no logon servers available to service the logon request".

Yes I have connectivity between the two machines.  I can actually use
SMBCLIENT from a samba machine and connect to the Laptop and reach
shares.  To do this of course I need to know the userid/password of a
valid user on the machine -- but it does work.

Any assistance would be greatly appreciated.

Thanks,
Henry
