At work we have a T1 line and then we have a cable connection through charter both on the same network. If i know the IP address of the charter modem, and I wanted to tell my NIC to use that instead of the T1 line would I just change the default gateway on my card to that of the modem?

Yes. Provided both routers are on the same subnet your NIC is on.

Well, when I set the default gateway to the charter modem, win 7 tells me im having DNS problems and I cant get to the internet. So I changed the DNS server from the address of the charter modem to the address of our DNS server and the problem persists.

Any thoughts?

Typically, DNS servers are not restricted to who uses them for name resolution. But it's not out of the question. So, yes, you should use the appropriate DNS server for the ISP circuit you are intending on using.

With that said, have you tried pinging the DNS server for Charter?
