W2K connectivity to Samba server

[Curtis Vaughan <curtis@npc-usa.com>]

Anyone have any ideas about the following problem.

We have a W2K Advanced Server as a PDC in a domain: WINDOMAIN
And we have a Samba 2.x server as the PDC (through LDAP & PAM) of 
another domain: LINUXDOMAIN

Any computer in WINDOMAIN can access shares on any computer (Linux, 
Windows, etc.) in LINUXDOMAIN (provided the appropriate credentials are 
used for LINUXDOMAIN) except the W2K PDC. No matter what, it cannot 
access any shares in LINUXDOMAIN. It just keeps reasking for the login 
and password, saying that the previous login/password attempt was: 
"Incorrect password or unknown user name for:"

NB: We also have an NT4 domain: NT4DOMAIN, which the W2K PDC accesses 
just fine.

Of course, I use the convention LINUXDOMAIN\username for logging in.

Any input would be most appreciated.

Thanks!
