Server 2012 R2 NIC Domain Authentication failure

-

i have been working on development of locked down closed test network using server 2012 r2, both standard , datacenter versions.  on past several months, recurring problem has plaguing network.  able add computers domain , log them fine.  time passes, if reboot random server, server lose domain authentication nic.  so, when log in, server reports cannot connect authentication server, nic not show the domain name instead shows "network 3" or "unknown network" status of "public" or "private".  have opened firewall on dcs wide open, removed , re-added system domain, , after reboot issue returns randomly.  if perform reboots on either 1 of domain controllers, experience problem, resolved disabling nic re-enabling nic.  cannot seem pinpoint causing problem @ all.  here basics of servers:

primary domain controller:

 - dell r330 running server 2012 r2 standard

alternate domain controller:

 - hyper-v instance of server 2012 r2 datacenter

member server 1:

 - dell r730 running server 2012 r2 datacenter , hyper-v binaries installed

member server 2:

 - dell r730 running server 2012 r2 datacenter , hyper-v binaries installed

member server 3:

 - dell nx430 running storage server 2012 r2

member servers 4-6:

 - hyper-v instance of server 2012 r2 datacenter

some steps have taken are:

- rebuilding dns on both dcs (dns works champ no errors @ @ point).

- rebuilding alternate dc after data replication errors noticed (replication functional no errors on 4 days now).

- opening firewall allow tcp , udp ports programs , ips between servers.

- added dns suffix nic settings after systems added domain.

does know going on here or have ideas? help is appreciated.

hi anthony matlock，

>>the nic not show the domain name instead shows "network 3" or "unknown network" status of "public" or "private"
