Here are the facts,
1) we have a NT Domain running over a Samba Server under Linux platform through Windows Services.
2) every machine in the net runs Win98 and log into a Domain call "SISTEMAS" an into a workgroup with the same name.
3) we install a PC with Windows Server 2003, and the users i use to logon are the same that in the Win98 PCs. It gets access to the workgroup, but i can't tell it to log into the domain.
4) when we tell ws2k3 to log into the domain it ask to a user with authorization to do that, but no matter what user we use, it tells us that it has denied access.
What are we doing wrong (i suppose varius things but...)?
