Active Directory not functioning

I cannot use AD Management tools.  When I try to run AD Users and Computers, I get
Server is running Windows Server 2012 and I do not have a good backup of AD.

DCDIAG output shows error 1355 that it cannot contact the GC.

Here is the output of a couple of NLTEST commands:

nltest /DSGETDC:seward.local

In addition, the NIC is stuck on the Public firewall profile.  I've tried putting Letwork Location Awareness on Automatic Delayed start, but it still won't come up as a domain for the firewall profile.  I've tried turning the firewall completely off, but still get the same responses as above.
