Both are running Windows Server 2012 R2 Standard.
When I try to run the DCPromo, I receive the following errors below. Any ideas where I can start to troubleshoot? I am able to ping server1 from server2 without any issue.
Verification of prerequisites for Active Directory preparation failed. Unable to connect to the replication source domain controller server1.contoso.com..
Exception: A directory service error has occurred
