So last night we swapped out a verizon modem for a newer one. This sits on a network with a server and they seem to be causing problems with each other. I have all clients pointing to the server for DNS/DHCP and then forwarding all DNS requests to the modem....while this works for the internet nothing internally resloves now....any ideas?

Break out nslookup on one of the client machines and see where things end up going and what you can resolve internally. Also check and see if that modem isn't trying to take over dhcp. That was my very first suspicion from reading this thread.Jumping on the IT blogging band wagon -- http://www.jefferyland.com/ -

Are you sure the new modem can act as a DNS proxy? Try a public DNS server temporarily.We responded to the Year 2000 issue with "Y2K" solutions...isn't this the kind of thinking that got us into trouble in the first place? -

I actually have been investigating that, even called Verizon (which has some pretty well trained techs I might add). I wanted to be careful about disabling it because their device says that it will disable Public IPs if you disable the private internal DHCP server. Their techs confirmed that this is only the internal portion and not the actual WAN addressing (which would be stupid if it did).

@Ahriakin: I checked with verizon and they it could...I have all clients getting leases from the server which provides itself as the primary dns server and the modem as the secondary.
