A problem is preventing Windows from accurately checking the license for this computer. Error Code: 0x80070002

Check if the following files are present in the System32 Folder

%SystemRoot%\System32\secupd.dat
%SystemRoot%\System32\oembios.dat　
%SystemRoot%\System32\oembios.bin

If any of these files are missing, restore these files, from the setup disk, I386 folder or from another system.


d:\I386>expand oembios.bi_ %SystemRoot%\System32\oembios.bin
d:\I386>expand oembios.da_ %SystemRoot%\System32\oembios.dat

where %SystemRoot% is your windows installation folder (eg. C:\Windows)Reboot the system.

Your problem must be solved. After rebooting some messages about MS software licenses may pop up. Just ignore and reboote once more. If problem with licenses persist than re-register them.
