I've built a domain with three Samba servers, got scripts to do most of the admin from the master server and all that works fine - I just have a problem with Windows clients. Samba/Linux users are created - then using smbclient on any of the Linux boxes allows me to connect straigt away, however on the Windows clients (2000/XP) I sometimes can't get a login for twenty minutes or even longer - Windows returns with " Domain Not Available". Once they finally log in, everything works as it should including mapping drives to the Master server when their home directories are on the slave, profiles, net time and all is fine.... I've done the XP reg hacks - anyone had s similar problem?
