Error 0x8007007f: A problem is preventing Windows from accurately checking the license for this computer


After you install SP2 for Windows Server 2003 x64 you get the following error message when you try to login using local console or RDP:

A problem is preventing Windows from accurately checking the license for this computer: Error Code 0x8007007f

After performing some research on the internet, this appears to have been a very common problem. A simply reboot fo the server, after the initial post-SP2 install reboot, appears to have resolved all of the problems.

Simply to help other people find this article here are some event logs which were also found on the system after the installation:
