Problems with DNS Replication after upgrade
I created a new A/D Server 2022 to replace my A/D Server 2012. The install completed and the FSMO roles transferred fine. However, I cannot manage the A/D GPO. In looking at the logs, it appears that DNS cannot replicate.
Password hash synchronization failed for domain: mrc.net, domain controller hostname: MIDSRVR01.mrc.net, domain controller IP address: 172.16.1.43. Details:
Microsoft.Online.PasswordSynchronization.SynchronizationManagerException: Unable to open connection to domain: mrc.net. Error: There was an error establishing a connection to the directory replication service. Domain controller hostname: MIDSRVR01.mrc.net, domain controller IP address: 192.168.99.12 —> Microsoft.Online.PasswordSynchronization.DirectoryReplicationServices.DrsCommunicationException: There was an error establishing a connection to the directory replication service. Domain controller hostname: MIDSRVR01.mrc.net, domain controller IP address: 192.168.99.12 —> Microsoft.Online.PasswordSynchronization.DirectoryReplicationServices.DrsException: There was an error creating the connection context. —> Microsoft.Online.PasswordSynchronization.DirectoryReplicationServices.DrsCommunicationException: RPC Error 1722 : The RPC server is unavailable. Error creating the RPC binding handle
The original A/D Server 2012 is multi-honed and it appears DNS is trying to use an IP Address on a private segment 192.168.99.12 which isn’t available to the new Server. The new server is on segment 172.16.1.x.
If I look at DNS, the server IP addresses appears in this order. How an I make the 172.16.1.43 the primary address?
How can I change the IP address to point to the other segment?
