Hello all, I am new to this mailing list, so please forgive me if this is a common question. I am using Samba 2.2.8 as the PDC in a test environment. I have a problem when I turn off the PDC Samba server and the XP client for the night, the next day I cannot logon the next day (after starting the SMB server and Win XP). My Win2k clients have no problems logging on. I set the Samab PDC as WINS server and the WinXp client to see it, though this should not make a difference. I still have the same problem. The only solution is the WinXp to re-join the domain. Then all is good. I can even restart the PDC Samba and it will work. Steve O.
