I seem to have a real odd problem that seems to escape me. I have two servers - both of which are ad controllers. My Problem Child is Windows 2008 R2, My other is a Windows 2012R2 that runs no problem.
If I go into the monitor section of DNS and run both the Simple Query and Recursive. The Simple will Fail, and the Recursive will pass. These same test work fine on the Windows 2k12 system.
I have also tried doing an NSLOOKUP ans well as flushing the dns. Reboots make no difference. Nothing is logged and turning on debugging yields no leads. Additionally, I have turned of the Windows Firewall, McAfee AV and Malware Bytes.
I have all windows updates though July 2019 installed. DNS on this system just does not want to answer any queries. Since the second server is responding, the problem is not catastrophic, however if the second server is rebooted -- that is it.
I have also tried changing the bind order (nics and ipv4) and disabling the hyper-v nic. No luck.
There are 15 workstations and two servers
I was thinking to try re-installing the DNS server (Remove and Re-install) on this Domain Controller, but I am a bit nervous of messing with it as it holds all FSMOs.
Any one have any better ideas or insight?
