Corrupt AD database
Posted on 2014-10-06
Ok so here's the deal. We have a corrupt DC, but I cannot simply demote it because a previous admin put Exchange on it. I've worked with Microsoft and the safest method to resolve this is to move Exchange to a new VM. This is not an easy process since we don't run a DAG, but is in the planning process.
In the mean time here is my issue, any new user added can access OWA and email, but no other network resources such as terminal servers or network drives. My hunch is that it is because the corrupt DC is handling the authentication request and since the DC's aren't replicating it doesn't see the user as valid, but the good DC is handling the OWA request. So how can I force the authentication to look at the working DC? I've made sure all FSMO roles are with the good DC, but it still didn't work. Obviously the fix is to move exchange and kill the bad DC, but until then I need a workaround.
They are both Windows Server 2008 (one of them being R2).
