Network folder access disappears mysteriously

I have a strange network folder access problem. After a certain amount of
time has elapsed, anywhere from 10 min to an hour, I can no longer access
the network folder. The message says access denied, or simply hangs the
file explorer.

The big clue is that I can restore folder access immediately if I go into
control panel / network, and "repair" the LAN connection. Then after a few
min, the problem will happen again.

The system is a Dell Precision 470 with the Intel Pro 1000 MT onboard
Ethernet, running XP Professional. The network settings are very simple,
just TCP/IP with automatic DHCP, accessing file shares managed via an Active
Directory Domain server.
 
I forgot to mention - the entire time, the TCP portion works fine (can
access the web, ping servers). It's just the NetBIOS that seems to randomly
drop the connection.
