How to fix Server 2012 with unidentified network.

Installed a fresh copy of Server 2012. It got DHCP from the firewall and came up. I installed all the updates. Then I renamed the server and changed the IP from DHCP to static. Plugged it into the network and it says unidentified network. I uninstalled and reinstalled the NIC and nothing. I cut on network discovery and nothing. Changed IP's again and nothing.

I plugged it into another Domain, cut on DHCP and it started working. Put it back on static and moved it to the other network and it changed again but still working.

Thanks,

And did you try the same cable with another PC or laptop? Just to make sure that isn't where the issue is? I had a NIC go the other day and it was still giving blinking lights but showed uniedntified network. Do you have another card or maybe like a USB adapter you could temporarily use(usb to ethernet "RJ45" or even USB to wifi just to test it).

Have you tried in command prompt -
ipconfig /release
ipconfig /flushdns
ipconfig /renew

Okay great, ha ha always crazy how these things act sometimes. Setup 100 PCs the same and get 1 that has a random issue.

So removing and adding to domain/workgroup worked along with changing the dns/subnet mask/IP/gateway (you chose to do this by adding back to dhcp then back to static) did work? Or that it was indeed the trust issue?

Why close the question if I answered it?

Apparently it did lose trust but moving to a couple different networks and back fixed it.
