Hi,
Please help I have inherited a domain and it is in a very sorry state.
DC1 - Site A, PDC, GC - IAS Server, File Server
DC2 - Site A, BDC - Exhcange Server
DC3 - Site B, BDC - File Server
Connection was made like this DC1 - DC2 - DC3.
From what I can gather DC2 had a hardware issue and the drives were removed and put in another system. This has been left with this since 2013.
I have run a dcdiag on DC1, DC2 and DC3
DC1
Testing server: Default-First-Site-Name\DC1
Starting test: Replications
[Replications Check,DC1] A recent replication attempt failed:
From DC2 to DC1
Naming Context: CN=Configuration,DC=Domain,DC=local
The replication generated an error (8614):
The Active Directory cannot replicate with this server because the t
ime since the last replication with this server has exceeded the tombstone lifet
ime.
The failure occurred at 2015-08-21 11:06:11.
The last success occurred at 2013-12-13 17:11:12

DC2

From DC1 to DC2

The replication generated an error (8606):

may not exist because it may have been deleted and already garbage collected.

The last success occurred at 2015-06-22 13:42:27.
1801 failures have occurred since the last success.

The PDC - DC1 is stating two of the other domain controllers are tombstoned I require to get active directory operating to enable to enable me to start to migrating over to 2012 Server.
Should I be believing that DC2 and DC3 are both Tombestoned and demote them and promote them again?
Any assistance with this would be most helpful.
Thanks
Martin
