I have two servers that I inherited when I took this position. Around April 2012 there was a network change and since them, the servers have not replicated. I ran dcdiag and received errors as well as ran repadmin to see if there were issues and the primary does not show any replica data, nor does the secondary. Could the secondary have tombstoned? If so, should I demote it, then promote it again? I need to keep it the same name.
I'm having the network admins ensure all AD ports are open between the two subnets.
I can attach logs if needed.
