Just recently one of our DC's at a remote site is no longer replicating to our primary data-center/site.
From the affected DC and local clients at site B:
1. Unable to browse \\SiteA-DC\netlogon
2. Unable to connect to network shares on SiteA-DC
3. I am able to browse by IP\share of SiteA-DC
4. Domain clients at Site B are unable to auth to domain shares at site A
See attached DCDiag output
