keep losing drive mapping

I'm on a Windows 2003 domain and my drive mapping keep getting disconnected.  What should I look for.  I'm going to attempt to get out of the network and then rejoin the network.  Any other ideas on how to resolve this issue?  I also notice that I cannot even get into my mappings via the run command as well.

When do you notice it? At logon?

This occurs after loging onto the network.  The first thing I do is to check the mappings and they are all disconnected.

If you manually type the command

net use * \\servername\sharename, will the drive map correctly or do you get an error?

When I attempt this:  net use * \\servername\sharename

I get a message stating that network cannot be found.  I had only one user with this issue and today I came in and now another user is having the same issue.

Any ideas?

I don't mean to insult anyone, but did you type your actual server's name and share path?
