WINDWOS BROWSER PROBLEM

We are running a Windows 2003 sp2/ Windows XP Domain with 6 vlans/networks. We have two domain controllers on one vlan/network and all the machines in the other vlan/networks authenticate to these machines. These DC’s are also running our DNS.

When I open up My Network places on any server or workstation, and then Entire Network, I can’t see all of the servers/workstations in our network.

I know the servers/workstations are still there because I can access them by typing \\computername in the Run dialog box. From what I understand this sounds like an issue with the computer browser service…

But what do I do to fix it?
