When activating Windows from the Campus Agreement, I get an error "0x8007232B: DNS name does not exist".
You must download the activation file from the Windows for UI Owned Computers offer in your WebStore order history to activate Windows with the University activation server.
To activate Windows:
If you still cannot activate email email@example.com with your external IP address, computer name, and approximate time you last tried to activate it. Note: Computers will attempt to reactivate about every 90 days. If your computer is disconnected from the campus network for long periods of time, you may need to repeat this procedure.
