[Samba] Domain join OK, but testjoin not and authentications not working.

[pivert]

Dear all,

This is now for weeks that I try to get samba working again. This is 
urgent as all users profiles are on this server.
Everything was working well, until we got Welchia Virus. We removed the 
virus, and updated our servers to SP3 + Windows2000-KB823980-x86-ENU.exe 
patch.

I removed the SP and the Patch, but I'm still unable to correctly join 
the domain.
I upgraded to Samba 3.0.1 without success.
The LinuxServer account is well added on the Win2KServer through the 
Active directory.
I added the admin password with wbinfo --set-auth-user...
A win2K WS can join the domain.

Please help, I'm out of ideas.

I always have the same symptoms :

LinuxServer samba # net rpc join -S Win2KServer -U Administrator
Password:
Joined domain DOMAIN.
LinuxServer samba # net rpc testjoin
