Heeeeelp!
We have as issue where intermittently we cannot see all servers when browsing the network but can see the domain (it shows the Windows domain but clicking on it does not expand it to show connected servers/PCs). I have flushed DNS caches, renewed IPs, checked DNS and WINS server/services (both happen to run on same 2003 Server along with DHCP). I can ping server addresses and their name which is resolved to the correct IP but still cannot see them. The weird thing is that if a user connects to the VPN I can see it under the domain but nothing else and they cannot browse the network either. Again, heeeelp!
