The RPC server is unavailable - Error Code:6ba After update

I just updated to 4661 and now AD Audit is unable to connect to my domain controllers. When I go into Domain Settings and tell it to discover Domain Controllers, it says "Domain Controllers cannot be discovered" When I try to manually add them, it says they already exist and it will not let me save my settings. When I go to http://localhost:8081/runQuery.do and run select * from adsmdcconfiguration it says " The RPC server is unavailable - Error Code:6ba." I have rules in the domain controller firelwalls to let AD Audit through, but just to test, I turned the firewall off on one DC and have allowed all on my AD Audit computer. That did not fix the issue.

What can I do to fix this?
