So I had to reboot one (I have 2) of my domain controllers (Server 2008) and upon logging back in, I got the limited or no network connectivity..no internet, nothing. I had to reset the NIC before it was back up and running. Now is this tied to the way I have DNS set up? Right now, it's set up like this:
DC1 IP 10.0.1.220
Primary DNS: 10.0.1.220
Secondary DNS: 10.0.1.221
DC2 IP: 10.0.1.221
Primary DNS: 10.0.1.221
Seconday DNS: 10.0.1.220
Should DC1 Primary DNS point to DC2? Or I should check something else?
