Not sure how and why this has happened, but managed to lose connectivity with one of our DC's @ remote site after a reboot.
Now, cant get to assign a static IP to the VM because its using an old adapter somewhere, even after removing it from the VM and host....

Ideas?

Setting static mac doesn't help, overrides it and assigns the same one!

You could have created a new virtual machine, DC and DHCP server, in the time, you've fiddled with TCP/IP stack.

I would start to create a new VM, prompt to DC, create DHCP server.

if your network stack on this VM is suspect.

But there must be an issue elsewhere (i suspect firewall - as replaced recently) which is killing dhcp etc...

check it out below link

you need to refer Jack MVP post

http://answers.microsoft.com/en-us/windows/forum/windows_7-networking/problem-with-windows-7-starter-autoconfiguration/443696f3-52b6-476e-b6fc-e18f74f9d8b4

Type netsh winsock reset in the Command Prompt , and then press the Enter key.

Do the same process for refreshing the TCP/IP just replace the typed command with.

netsh interface ipv4 reset   press Enter

netsh interface ipv6 reset   press Enter

ipconfig /flushdns   press Enter

Restart your Computer.

It was caused by a firewall.  
Modus - this is a different question, but seemed to be the same.
