Hi,
Currently have domain three domain controllers (DC1, DC2, DC3), with the FSMO roles spread across DC1 & DC2. DC1 & DC2 are located in site A and DC3 is located in site B. Due to misconfiguration of the network, DC3 wasn't able to communicate with DC1 or DC2 for quite some time, resulting in the tombstone lifetime being as reached i.e. 180 days. As far as i understand, the DC3 is essentially unrecoverable now because of this. What are my options here to get DC3 removed from the domain completely, added back to the domain and promoted to a DC?
1. Restore network communication is, demote DC3 so it's just a member server then re-add to the domain and promote to dc?
2. Force removal of DC3 from the domain and perform metadata cleanup then re-add to the domain and promote to dc?
What makes things worse is DC3 is also a print server which I would like to remain intact. By performing these action, I presume that any computers establishing a connection with DC3 will be broken and will need to be rejoined to the domain?
Looking for some input for a clean resolution to my problem.
Cheers
