Hi, I made an error of joining a Samba server to the NT domain with host name hostname.domain.com. NT won't allow clients with "." in their NetBIOS names, but somehow Samba created this hostname in Server Manager. Now I can't remove it. Even after I killed Samba box, waited 2 days, the name is still there. If I tried to remove it manually from Server Manager, I get "The user name or group name parameter is invalid". May I ask is there some way that I can remove it using Samba? Where is the database kept in NT? Regards, Norman
