Hi,
Every so often a server, even the domain controller would lose the domain. The NIC would show connected to "network 2 / private" rather than our FQDN. The fix in the past was to simply disable and reenable the NIC. The NIC would then show our FQDN and everything was good.
We had to shut down last weekend because of a cooling issue. When I brought everything back up, our Hyper V NICs would not "find" the domain. Instead the NICs showed connected to Private / Network 2 rather than domain / FQDN. The only thing that fixed it was to ping our FQDN, disable and reenable the NIC on each. Is this a problem with our domain design or DNS, or it this a bug?
Our domain level is 2008 R2. The 2 domain controllers are 2012 R2.
Thanks for any good info.
