There is currently no DNS service installed on a small network NT4 Server Domain Controller, as all local machines can access the network without any problems. All computers have a manual TCPIP address allocated with the DNS entry set to an external DNS address, for Internet access.
However one computer is now being used remotely using VPN client software provided by a Watchguard Firebox. When connected via the VPN this computer seems unable to browse the local network, despite having an internal VPN IP address allocated and so it would appear that the NT4 server DNS service needs to be setup!? ( whilst retaining Internet access ).
Please advise re. the above issue and, if DNS requires setting up, confirm the DNS setup procedure for both the NT4 server and Windows 2000 / XP workstations.
