Unable to browse the network remotely

My Remote users can login to the network but cannot browse the network. I have check the DHCP Scope options and the wins server (ie), WIns/nbns is configured. Also i have the Wins,Ras,and DHCP Server on the same Computer. I believe this has to do with name resolution. I can only ping the ras server on the network when i am loged on remotely. The users in the office are fine with the name resolution.
So What am i doing wrong or need to do.
Any Clue guys????.
