It is a business network. I have not made any domain changes recently. It is grabbing it from DHCP. I checked using ipconfig /all and x.x.x.x is showing up as the primary dns, not sure why dcdiag.txt is showing it reversed. Also, for some reason the machine was grabbing an IP from one of the NICs on my DC from DHCP that wasn't in the DHCP scope. Also, this NIC's IP address was showing as a forward lookup zone for my DC, I removed the entry. I disabled that NIC, I am not sure why my predecessor enabled and configured it to use this IP, but no problems have arisen from disabling it. I think my enterprise AV may be messing with the DC, so I took it off for now. I will know where I am at after a lunch-time reboot It turns out this problem is with my DC and not the host machine, I tested with another system that was known to be working, so I need to have this thread moved. I am running Server 2008.
