So I had a power outage yesterday and it was longer than my UPS's battery (over an hour).
Anyhow, the hyper v server power went out. After the power outage I booted it up, but the networking (external) on any of the nics does not work anymore. I have 3 nics in it, one for the host and one each for 2 vm's. I should say networking does not work over the nics anymore. Cant ping to the server from outside, nor ping from the server.
If I go into sconfig it shows the hosts nic, as usual, plus a test internal network nic I had not yet removed. using coreconfig I can see those nics as well, they show enabled and connected. Also the switch I plug into shows that they are connected (lights on, 1 Gbit connection) All networking parameters are as they should be (ip, subnet, etc)
Using core config VM section, both vm's are up and running.
I have tried restarting, powerting off completely and restarting, enebling/disbaling the nic, plugging into different switch ports, tried a different switch. All my other servers are running fine, including two vm servers, so its unlikely external to the server.
At this point I really have no idea what to try next. I dont have any spare nics to go try, but I doubt its NIC's considering all 3 are not functional (or better to say the network is not running over any of the 3 nics)
Any suggestions as to some things I can try?
