I have about 110 Windows 2003 Domain Controllers. On average, about once every 3 days, a server at random will enter into a state where it is still pingable but the admin shares are not accessible, you can’t run Computer Management and connect to the server. You can’t Remote Desktop to the Server. You can’t VNC the server. When you try to connect to c$ the following error message is displayed – “An extended error has occurred.” or “System error 64 has occurred. The specified network name is no longer available.”
The domain is a Windows 2003 Active Directory domain. I have also verified that all servers have the correct time and are getting their time server from the Domain Hierarchy.
Has anyone seen this behavior? Any feedback would be much appreciated.
Thanks,
Mike McCormick
