I need some advice.
I have a testing lab that has 3 2008 Domain Controllers.
I have not been monitoring this domain but 2 of the DC's have stopped replicating and now are past the tombstone time limits. These Domain controllers are up but it looks like some time in December they stopped replicating and now DNS is having a lot of issues and I need to remove them.
I cannot log into them because their DNS will not work to validate my credentials, I have tried to reset the local admin password, that won't work either. Both of these Domain controllers did not hold any of the FSMO roles. I want to demote them but since they are still live it's giving me issues. Should I just power them off and force removal from the one still living? I'm not sure how to do it since they are still detected on the network.....
Any advice is appreciated. I did try to force replication by a change in the registry and changing the tombstone date but that didn't work.
