Server 2008 domain no internet with dhcp

We did a new server 2008 installation (the old server croaked and the system state backup was corrupt) and all the data's safe and accessible.  So we're good EXCEPT today (about a week after the new install) internet access dropped off altogether.  The exception was on one computer that had a static ip address.  So we made the other 6 static ip addresses and now we have internet access. But WHY would internet access drop?  The dns records AND the dhcp records all showed the same ip configs, they were all pointed right, all authenticated on the domain, and no errors showing on the event viewer.  We have a Qwest modem providing internet access, with a stand-alone Linksys router for wifi access, and a cisco switch.  The phones are all Cisco VOIP phones, and the computers connect to the telephones to get network access if that helps.

One more thing --the primary dns server address on the NIC ipv4 properties on this server installation points to 127.0.0.1 and not the 'dns' address on the server's administrative tools, which is the NIC IP address of 168.100.0.200.

Primary DNS on a DNS server will point it to itself first then it will forward it another server.

On the desktops, with DHCP enabled
1. Verify the DNS Settings (nslookup google.com on cmd)
2. Are you able to browse using IP address?  BBC.co.uk can be access using 212.58.253.67
3. If you can access web using ip address, try changing the dns on the desktop to 8.8.8.8 (google public dns)

Let me know how it goes.

That helped, but didn't totally fix it.  What finally did was to set the "router" in the dns configuration to point to the router directly.  Then it all started working again.
