When you click the Network Neighborhood, the system will try to contact a browser server. As Microsoft rules say, if you don't have a domain controller, then the master browser will be the computer with the newest Windows OS (or voting if they have the same OS). In your case Win XP. Try to disable "computer browser" service on XP machine. Then Win2000 will be the master browser. Maybe it wil work better.
