I installed a new modem, for which I had to enable DHCP, and ever since our network has not been able to resolve domain names in our local development environment.
If I am to log on to the server and open up a browser, the FQDN is resolved at the root of our IIS server, but any sub domains are not.
However, on network machines, whilst we have no problems connecting to the network no local domains are being resolved, including the FQDN.
NS lookup returns the default gateway address of the server, but nothing else.
I am slowly learning about DNS here, but I am trying to keep the office network up while I plod away at this, so blindly fiddling with DHCP settings doesn't help me.
Any advice would be appreciated. I've done a lot of the troubleshooting stuff already, but as this would appear to relate to the new modem and DHCP, I'm trying to target this specifically, and it's difficult to find the info I'm looking for.
This is on a Windows Server 2003, running IIS 6.0
