So this issue shows up at our remote office (connected via site to site VPN).
This is the DC for that office and after having some odd "hiccups" (NOTE DC1 is in Chicago and shows no issue).
Running BPA I have four errors now.
NIC1 should include loopback address but not as first entry (it's list last).
NIC1 DNS should be configured to register its IP address in DNS ( I checked the box on the NIC properties).
DNS Zone Trusted Anchors secondary server must respond to queries for the zone.
Zone _msdcs.domain.local is an ad integrated zone and must be available.
Any help would be appreciated.
