We have 4 locations and are running Windows 2000 Server. Each site has at least one domain controller. About once a month or so, one or two users at one site receives an error when trying to log on that there is no domain controller available or their account was not found. I have to log in to the local machine, disjoin them from the domain, shutdown/restart, log back in to the local machine then add back to the domain. This only affects one or two users (normally) in one location but the location changes from month-to-month and is rarely the same user affected. This problem occurs infrequently and there is never anything in the event log on the local machine nor the server to indicate what the problem may have been.
Anyone have any idea what is causing this and how to resolve it?
