We have replaced a HDD from a Win7/Office2k10 machine which was licensed using our VMAT server.
Now when we try and re-licence Office it fails in to console with - unknown error (0x8004fe33). When opening word on the client machine it says 'Microsoft Office Pro plus 2010 cannot verify the licence for this product. you should repair the office program by using control panel'.
We are using the same computer name as before. Win7 licences fine.
Another thing which is odd, is that i managed to get the same issue on a machine that was licensed fine and has not had any changed to the machine (i must have re-licensed this too).
