I have a Win2k domain controller, a RH8 server running Samba and a dozen clients dual booting with RH9 and XP. I need the RH9 client to authenticate at logon to the Win2k domain and then mount and access home directory on the RH8 server. We have configured Samba and NIS and smb on the client but clients still get authentication errors. The log file on the RH8 server indicates that the authentication was successful but the client gets an error and can't logon.

The RH8 server is not a domain controller.
A user can log on locally then access home folder on RH8 server and see the W2k domain and access files via the network servers tool.
There is an account on the Win2k dc for the Samba server, "allow previous versions of Windows 2000" was checked at creation.
The Win2k domain is in native mode.
