Possible reason:
1. ensure both servers are on the same subnet 2. check your DNS settings primary DNS should be DC1 3. check your firewall settings
Solution:
Verify the startup value and service status,make sure these are running:
- the Remote Procedure Call (RPC),
- Remote Procedure Call (RPC) Locator
- Kerberos Key Distribution Center.
Reason for this senario: The RPC locator was stop.
Start this service and give both DC a restart.
