I got Active Directory with few computers- ~15 around. Mostly - all clients are Windows XP SP2 or SP3. Some of them ar gettings following errors (see attached images), after what, they are not any more able to connect to AD or server without logging off and on again.
If client computer just wiats for some minutes, then error disappears and everything goes normally.
System event and Application event logs shows errors, attached print screens.
It is very annoying for users, who uses shared printers from server, as they cannot print at that moment. I will attached prin screen from error from Word, when I will cach it.
Server is Windows 2003 SBS.
