2 - 2008 R2 DC's cannot access each others services
I have 2 2008R2 DC's that are able to ping each other but suddenly cannot access any services amongst each other.
If I try to Remote Desktop, I get the login box but then it just won't connect.
I am also getting AD errors - not replicating between the 2 DC's.
I took the firewalls down and that is not the issue either.
Any suggestions?? Thanks in advance everyone!!

It could be an DNS issue. Try running a DCDIAG

Other DC's work just fine with each other, its just these 2 that have problems with each other.
I got some errors on one of the DC's using the DCDIAG:
* Identified AD Forest.
Ldap search capabality attribute search failed on server FS4, return value =
81
Got error while checking if the DC is using FRS or DFSR. Error:
Win32 Error 81The VerifyReferences, FrsEvent and DfsrEvent tests might fail
because of this error.
Ldap search capabality attribute search failed on server WAP1, return value
= 81

Nothing replicates from a RODC. What events do you see in the event logs on the RODCs?
nattygreg:
sounds like your ntds files are corrupt, if thats the case its a rap, with that much errors its better to reload these servers. than to spend countless hours, pulling hairs for no reason.
I agree with Nattygreg. Wipe them and start over. Do the Metadata Cleanup in between. You have to consider time spent fighting with something like that (Time is Money) and if the money spent (on your wages if nothing else) is worth it to the company. In probably two hours you can wipe the machine,...do the Meta Data cleanup,...reinstall OS,...DC Promote,...Done!
