Windows 7 Activation Error: 0x8007232B

I have used Windows 7 Ultimate for some months, but as the license delivered with the computer is a Windows 7 Professional - I had to downgrade. You could say that going from x86 to 64 bit is an upgrade  - and the additional functions in Ultimate will not be missed.I tried to activate my newly installed Windows 7 64bit edition today. and got the following message:

Code: 0×8007232B
Description: DNS name does not exist. 

This is a strange error. Read about the solution here.

This solved my problem, and now my Windows 7 configuration is up running. Now I only have to install all applications and copy over the documents. Maybe I this time should make a disk image of the setup :-) I really recommend having a virtual disk with the key applications you need installed. I have that running providing me with access to VPN, mail, intranet etc. This way I stay available even if my setup is not ready.
