My domain controllers on the Azure and on-premise used to replicate the directory until few days ago. I didn't realize there was some payment problem on my Azure subscriptions and my services were disabled. After I made the payment, I recreated the removed VNet gateway and established the site-to-site VPN.
Even the domain controllers are able to ping and nslookup to each other now, the directory service has stopped replicate between two DCs. There are many Error 1863 and Warning 2089 on the event viewer.
I tried to look for solutions of Error 1863 for a day but I found very little knowledge and solution about it. I also tried to demote DC2 (on-premise) and promote it again. I got errors while demoting it. Below is the print screen of the error.
I have an idea now which is disjoin DC2 from the domain and force it to remove the AD role. Then, rejoin the domain and promote it to DC2 again. Can anyone advice if this is something do-able ? Any suggestions or advices are much appreciated.
