Thanks SD. I will take another look when I get a chance. The thing I do not understand is that if I do a restore (from the image hidden on the hard drive) the next time the machine is started it is back to square one

Could it be that the original file is corrupted?
From what I remember looking at it I can get the file version from the properties.
Oh! and when it was reloaded from the disc 'image' of it trotted to M$ and downloaded all the updates including SP3! So would I need the latest version of the file?
cheers gp
