I have a Windows 2000 AD domain. I'm using Windows XP SP1 on my workstations. I have the Administration tools for AD installed on my XP machine.
My problem is this. I sometimes lose my connection to Active Directory. I'll open Active Directory Users and Computers and sometimes see a "cannot find domain" or an RPC unavailable error. Restarting the PC will allow me to again connect to AD with Active Directory Users and Computers. I'm also able to sometimes get access by specifying a different domain controller in the Active Directory Users and Computers MMC. Sometimes it works, sometimes it doesn't. I'm not sure that this is a workstation specific problem. One of my co-workers has the same problem on his XP machine. Anyone have any ideas?
