See replication status and logs
repadmin /showrepl to see state of sync between Servers
See diagnostics about current server Issues
dcdiag to see more errors about sync
Check Options related to syncing servers
repadmin /options <SERVER|DC01|DC02>
Don’t rollback Domain Controllers being them a VM or not they will lose sync if the other DC was updated before and may corrupt the database.
Restore from backup details:
Is the system used for backups only available access throught the dead DC?
Point it’s DNS only to the available DC ( had some issues with Samba)
Samba will freak and start overusing IO for network in broadcast when authentication is requested,
more, samba will not start correctly when one DC is down change the resolv.conf
Backup took one hour and ~30 minutes to restore.
More the time it takes to copy over the network to the local machine.
Copy the Backup to the local machine before restoring!
