So this seems to be a pretty common issue when restarting servers, or having them on certain networks.
I am installing a new domain at the company I work for, and am doing some testing. Well I decided to ensure that the UPS works fine. It does. Hyper-V shuts down servers, with plenty of time to spare. A couple minutes later, server gets plugged back in, and after a little bit of worrying, the server comes back to life all on its own.
Success, right? Not quite.
I try to remote desktop to the servers, only to find I cannot access them at all. For some reason I can still connect with Hyper-V manager to the Hyper-V server and connect to the servers via the virtual console. Turns out they think they're on a "Public Network"
Now, changing this is easy by changing the setting in the Local Security Policy... but that's not a very good solution, because the next time the servers get shut down, I will need to change their network type from Public to Private again... Another option is disabling the network adapter and then enabling it. That seems to detect the domain fine.
So how do I make these servers realize they are on the domain network when all the DCs have been shut off and are just coming back online?
DC1:
IP: 10.20.10.1/24
GW: 10.20.10.15
DNS: 127.0.0.1 (maybe this needs to change to 10.20.10.1?)
DNS: 10.20.10.2
DC2:
IP: 10.20.10.2/24
GW: 10.20.10.15
DNS: 127.0.0.1 (maybe this needs to change to 10.20.10.2?)
