We have found a similar problem in our LAN of 170 pc's. It seems to have
been corrected by a number of fixes...

A switch with a faulty port was removed, flood control was turned on on the
other switch, filtering was switched on in the router. LANAlyzer failed to
pick up any problems, as did ManageWise (only seemed to add to the
problems). The production server was constantly sitting on 0% utilization,
yet the network ground to a halt everytime there was an IP request, and
certain areas slowed and froze, to the point where PC's dropped off the
network. The biggest change was noticed when flood control was turned on the
switch. Also, watch your switch settings...where possible, lock the ports to
their needed speed, i.e. 100 Mbit for 100 meg NIC's and 10 for 10.
Auto-ensing seems to fail from time-to-time.

Cheers,

Glassy
