Are the systems using DHCP or Static IP's.. I have seen this problem with 2000 and an ME box failing to renew a lease when requested by the DHCP server. The ME box would not acknowledge the request to renew the lease, and the connection died. I solved it by going to a Static IP. I was also told that you could Disable Lease Requesting by the server, in which case a lease was permanent until you dropped the connection. You might want to check if Messaging was turned off on the XP and 2000 box's (to disable a messaging spam nuisance) in which case it might never request acknowledgement since a NT system uses messaging to broadcast.

The problem affects all the machines on the networks; they all lose connection simultaneously. We're trying various things to try to resolve the problem. So far, at my customer's place, I have replaced one of the switches, turned off Norton Personal Firewall on one computer, replaced the RJ45 on one cable, replaced one modular jack, upgraded the firmware in the router (one of the bugs resolved is a router reboot caused by a multicast, maybe that'll help), and rearranged the cables between the other switch and the router so that all of the active cables were on the router and all the inactive cables on the switch, which I then turned off (so, instead of two switches and a router, there's now one switch and a router). Will find out tomorrow afternoon if these latest changes have had any effect. I meant to check to see if the router is plugged into the UPS, will have my customer check that tomorrow.
