I have to comment myself. I looked at the system eventlog of the client 
maschine and found the following error message from the netlogon service:

"The domain of this computer (UNIWH) has been downgraded from Windows 2000 
or newer to Windows NT4 or older. This computer cannot function properly in
this case for authentication purposes. This computer needs to rejoin the
domain.
The following error occurred: There are currently no logon servers 
available to service the logon request."

Aha. That's a clear statement.
It's true that the DC was downgraded from Windows 2000 to NT4, because the 
original domain is Windows 2000/AD runinng in mixed mode, but every 
reference to "net rpc vampire" and "AD in mixed mode" says that this works. 
Is it possible that "net rpc vampire" works only partially when used with 
AD/mixed mode?

BTW: I'm not the first to encounter this problem. Another samba user (Kang 
Sun) reported exactly the same problem about a year ago, but didn't get an 
answer.

HELP!!!
Thanks.
