samba - May 2010 - 0x000006d1 while connecting with Windows Server 2008 to Samba server

Hi,

we had the same problem. The problem occurred after adding the role 
terminal services to the w2k8 server.
We solved the problem by disabling the policy "Always render print jobs 
on the server" inside the group policy object editor, Computer 
Configuration, Administrative Templates, Printers.

Regards

Thorsten
