mapped drive, server service/redirector repeatedly refreshing expl

Ive got a very wierd problem that I cannot figure out and have found no clues
on the Internet either.

I have a Windows 2003 server that has many shares hosted on it. It is my
domain controller too. The main big share that contains all users' home
directories, and gets mapped to all workstations' "H:" drives has suddenly
started acting bizzarely.

On every workstation, when you open up the H: drive in Windows Explorer, the
file list in the right hand window pane keeps automatically refreshing itself
over and over and over incessantly in some kind of infinite loop. The status
bar at the bottom of Explorer keeps alternating between the text string
"Searching for items..." and the string that tells how many objects are there
and the free space.

This happens on 100% of all my XP and W2K workstation of the network (over a
hundred machines).

If, on the server's console itself, I map the "H:" drive (or any other
letter for that matter) to this one particular share, I get the same exact
behaviour there too.

If I restart the server, after a fresh reboot, the problem is not there and
everything is fine until the next morning when I come into work, the problem
is there again. The only thing that runs at night is the backups (Veritas
Backup Exec 9.1) and if I don;t run the backups, the problem still occurs the
next morning.

None of the other network file shares (about a dozen) hosted on this box are
exhibiting this problem of repeatedly auto-refreshing / recycling the network
connection. Just this one that hosts all users' "Home Directories".

It's as if the server service itself is pushing out some kind of
auto-refresh command to all clients, and the problem is not in the clients'
redirectors themselves.

Help!!!!
