[Samba] Joining W2k-clients to Samba 2.2.3a PDC

[lists at hilboll.de]

Hello everybody, 
I have a problem joining Win2kSP2-Clients to my Samba223a-PDC. I did 
create the machine accounts. When I try to join the W2k-box to the 
domain, Windows tells me to enter a user name, password and domain. When

I enter the information of a Domain Admin User and my domain name, 
Windows tells me incorrect username/password. The logfile of that client

reads: 

[2002/03/15 14:37:01, 0] smbd/service.c:make_connection(381) 
  andreas logged in as admin user (root privileges)

Who can help me out? 
Thanks, 

Andreas
