DFS Replication failed to contact Domain Controller.....

Question

I have seen this error since the inception of this stand alone AD PDC instance of Windows server 2012 R2 Essentials. I understand that Essentials does not support other Domain Controllers ; Member servers ; or trust between Domains of any kind. I also
understand that DSF Replication is a service that replicates files between other servers and other domain servers that Essentials dose not want to talk to.
So my question is why am I seeing this DFSR error 1202  in my event log, if Essentials does not support communication to other servers and domain servers? Maybe a better question is why does Essentials even try to implement this
service? Do I even need to try to resolve this issue or should I just disable it and move on?

Hi, 
Did you mean that you did not configure a DFS server in the new DC but you get the DFSR error 1202 in your event log? Then the issue is not related to the existing SBS domain. 
Please try to turn off the Windows Firewall to check if it causes the issue. You could also refer to the articles below to troubleshoot the issue:
