I am currently running a Windows 2000 server based network. The server runs AD, DHCP and DNS services. I recently attempted to install an all in one ADSL modem\router\firewall, to provide internet access to all users.
I struggled to get this to work (DNS issues), until I found an article on the net suggesting a possible solution. It suggested deleting the root entry (.) in the DNS, and then entering my ISP's DNS servers in the forwarding section.
It seems to have worked, however I'm not sure if it is the correct solution.
Could somebody please explain what the correct solution should be?
