DFSR breaks after reboot

Question

I have set up a replication group and folder between two 2012R2 servers. Replication works fine until I reboot one of them. Then I get Error 1202 in the Events log with this message:

The DFS Replication service failed to contact domain controller to access configuration information. Replication is stopped. The service will try again during the next configuration polling cycle, which will occur in 60 minutes. This event can be caused by TCP/IP connectivity, firewall, Active Directory Domain Services, or DNS issues.

Additional Information:
Error: 160 (One or more arguments are not correct.)

I cannot tell which argument is not correct.

I am also puzzled why I was able to set up the replication initially, and it works fine, if the two systems can't talk to the domain controller.

I am not sure there is a shutdown timeout and that I am falling in to the 'Dirty shutdown' scenario because I can't find the events 1006 or 1008 indicating DFS stopping/stopped events. This is Windows Server 2012, so the hotfix for 2008 to change the DFS recovery should be applied. And, this is NOT a very active folder so, I expect there is nothing replicating at the time I issue a reboot.

And, when I try the wmic command to resume replication I get an error.

And, I get these messages after reboot.

So, Why am I able to create the DFSR group, and it works until reboot, then it breaks? If there is an AD parameter wrong, which is it, and why does it not find that when I create the replication group?

Hi,

Based on my knowledge, in general, after reboot dfs server, the server will contact the DC to find the dfs database and it should establish the dfs replication with other dfs servers again.

In your scenario, it seems blocked after reboot. Now you have already disable firewall, it shouldn't be blocked then.

I'm afraid for dedicated Support about such performance analysis you might need to contact Microsoft Customer Support Services (CSS).

It is also appreciated that the other members in our forum can share their experience with us about this scenario.
