Run nslookup from a client on your internal network and set for debug.
Query a few records and take a look where you're getting bounced to.
Repeat the same sequence from each DNS server.

Are your DNS server NICs hardcoded or running for Auto Detect with
speed/duplex?  If Auto Detect, hardcode NIC and switch port to same
speed.  See if that helps, too.

Steve: Funny you should say that because I've done that a few times. 

DNS stops - I removed the forwards - Restart DNS - DNS works.
DNS stops - I change the forwards - Restart DNS - DNS works.

I want to blame my server but I'm just not sure where the failure is.

Hello All -

This might be off-topic, but has anyone every had their Windows DNS/DC
server intermittently stop forwarding DNS requests?

I checked with the ISP and they don't recognize and problems on their
end.
