Can someone check my DCDiag.log and offer any comments.

Having a few issues with logons at the site.

 

I've run Dcdiag /v /c /d /e /s:%computername% >C:\dcdiag.log on one of the Domain Controllers.

 

Results are below if anyone can interpret better than I can :/

 

Below are some of the errors from the log.

Sounds like your backup system caused the DFS Replication to be paused, so it wasn't being altered while the backup occurred, and then it didn't get unpaused again.

 

How do you backup, are the backups working, is it a VM? Is replication paused?
