Have a W2K box upgraded from NT4. Installed a modem card and set up for dial-up internet access. Modem connects and works but can not get name resolution via browser or command-line. I can ping out to DNS server and webservers. Tested modem with W2K Server on another disk and worked fine. Must be software issue with Pro. Protocol, settings, bindings all seem to be in order. Tried re-installing OS via upgrade option but no change. Any suggestions? Clean install? TIA!

NT4 uses WINS for name resolution and W2K uses DNS. Check in your tcp/ip - advanced properties on the DNS tab make sure you have the address of your DNS server there. You will have to have one or the other (WINS or DNS)to resolve names. If you are using a dialup ISP they had to give you a static IP and a DNS IP or instructions to use DHCP which should load the DNS server dynamically. Run the command "ipconfig /all" from a command prompt, this will give you all of your addresses for DHCP, DNS, WINS and IP. Of course there are many things that could be cuasing your issue - this is where I would start.
