Hi Vegas16Lax,
could you post an ipconfig /all run on your server?
It seems like you are using 64.115.0.9 and 64.115.0.10 as DNS servers on your server TCP/IP properties. Did you have to change anything?

It is only happening on this dns server. There are two other dns servers in our site and when I run dcdiag on them, they report clean results.

I cleaned up a few things. But, the only real change I made was adding two Forwarders to my ISP's dns servers and now it works. Why would this particular server need forwarders and the others don't??? All three are DC's running DNS active-directory integrated/secure only.

I guess you have two NICs on that server.
The first NIC is 3Com EtherLink XL 10/100 PCI TX NIC (3C905B-TX) and, as I can read from DCDIAG results, it's using 64.115.0.9 and 64.115.0.10 as DNS servers.

The second NIC is Broadcom BCM5708S NetXtreme II GigE, showing in ipconfig output. This configuration seems to be ok.

In any case, I guess you should remove DNS servers from the first NIC settings, but it would be useful if you could give some informations about the services you are using on that particular server
