How do I know I have a browser problem
When you open My Network Places, the computer list you see is obtaining from the master browser of your network. You have a master browser issue if you have the following symptoms. 1) If you can ping a computer name, you can search it, you can map it, but that computer doesn't show or take long time to show up on My Network Places.
2) Net view command shows no lists or shows "System error 6118 has occurred. The list of servers for this workgroup is not currently available".
3) when clicking on Computers Near Me in My Network Places or workgroup name in Entire Network, the following error message may appear: "Cannot Access 'Computers Near Me' " or "Workgroup is not accessible" errors.
4) when click workgroup name under Entire Network Places, you get "Workgroup is not accessible. You might not have permission to use this network resource. Contact the administrator of this server to find out if you have access permission. The list server for this workgroup is not currently available."
5) Windows Explorer or My Network Places take a long time to open.
6) Event logs on servers show many master browser election messages.

My network has one subnet, one domain. The servers are runing windows 2003.
The clients are running a mix of win 2k and win xp.
All computers have current patches installed.
The win 2k clients can't browse the network through my network places.
The win 2k machines can ping and resolve computer names.
If I type the UNC in the browser it will find the resource, but if I go back
and try to browse to resource I get an error "the network path was not found".
The XP clients work fine.
I believe this problem appeared after the upgrade of the servers to Server
2003, but I could be wrong.
Anyone know what caused this?
