Driver signing broken

[Joel]

Hi,

I recently reinstalled Windows XP Home Edition and for some reason all
drivers, including drivers that came standard with Windows XP, like
USB mouse drivers, USB keyboard and USB Disk drives.

If I plug in a device like a Microsoft mouse into a new usb port it
will bring up the add new hardware wizard ask to search for drivers,
and then when it finds a driver it complain about the drivers not
being digitally signed, which is rubbish, but none the less every
driver is not digitally signed apparently.

So I went into System Properties -> Hardware tab -> Driver Signing ->
then set the action to Ignore, but that had no effect whatsoever even
after restarting.

Does anyone have any idea what is going on? I only formatted about 2
weeks ago, so it seems crazy that this should happen so soon.

Thanks,

-Joel

It's all fixed now. It turned out I had somehow lost most of the
catalog files in system32/catroot. So I uninstalled Service Pack 2
and reinstalled it and all my drivers now have their signatures back.
