Mapped drives from Server 2k3 disconnecting on clients

I have two servers with shared folders, one Win2000 Server, one Win2003 server.
I recently moved some users' folders and outlook .pst files to the Win2003
server and mapped them from there (they were mapped on the Win2000 server).

At around 6pm each day, anyone who is still logged in to the domain and has
any of the mapped drives in use, e.g. outlook open or are browsing files,
they get told the files can no longer be found and when trying to access the
mapped drives it says they are not available and that there is a time
difference between the client and the server (which was 3mins). I changed
that for one client and it fixed it for him for a while, but now it's
happening again.

This problem never occurred on the Win2000 server. The files and folders
have been moved to the Win2003 server to increase performance of network
shares. The backup of the server occurs at 9pm, so thats not the issue, and
there are no erros reported on the server or the clients in their event logs.

Anyone got any ideas?

accessing Outlook PST files on a network drive are not a supported scenario.
You should know this to avoid data corruption.

Also no errors in the security log, if you enable auditing through the group
policies?
Time differences are a possible reason for authentication issues.

You also can try to disable the autodisconnect from server side to network
ressources which are not in active use, but since you have an exact time
when the thing is happening this should not be the reason:
net config server /autodisconnect:-1
would be the command for this.

Are there any special tasks running at this time (like virus scan, shadow
volume copy snapshot etc)?
