Windows Server 2012 Activation failed: Error Code 0x8007232B DNS name does not exist.

You may experience issues when trying to activate Windows (Bulk License) key in Virtual Machine.

It may be one of the cases that you are not connected to the host domain. Please check your network adapters. If you have connected the VM to a private DNS, then try to disable that adapter and add a New Adapter as NAT and try to connect to the Host DNS and its internet connection.

Have your windows key and run the following command.

slmgr -ipk xxxxx-xxxxx-xxxxx-xxxxx-xxxxx
slmgr /ato

If above command doesn't work then try another option as below.

At command prompt

c:>Slui 3

this will open a GUI, where you can enter Windows 2012 KEY and choose option to activate.

This will probably work.
