samba - Nov 2003 - Problems joining W2K Client to Samba 2.2.8 on RH9

Hi,

i have some problems using my RedHat 9 Samba Server. I created Shares 
for my W2K Windows Clients. All Clients can access the Shares, so no 
problem there. Now i tried to join my W2K machines to the domain and get 
an error:

"Canot join domain, the credentials supplied conflict with an existing
set".

I read in some newsgroups that "net use * /d" helps but it doesn't

Any idea whats goind wrong?

My smb.conf:
