All Windows Drivers appearing unsigned?

[wolstech]

Hi all, this problem has been stumping me for a few days now.

Any time i try to install new hardware, I receive the typical Unsigned Driver "Continue Anyway" box. I am seeing these prompts for every driver i install, such as the "USB Mass Storage Device", and "Disk Drive" that install when I connect a new flash drive. On any other system, these drivers appear as signed and install without any dialog boxes, just the "Found new Hardware" balloon in the tray.

I've gotten prompts to install the "driver" for "Unknown Device" as well.

I'm not sure if the issues occurs with 3rd party drivers.

If I look in Device Manager, the drivers for every device listed appear as "not digitally signed". This includes things like the HAL and processor.

Anyone know exactly whats wrong here? I have no malware on the system and haven't been infected in over 2 years (last time i formatted). I haven't installed any updates recently that i'm aware of other than the IMAPI2 (KB932716) package, which i needed for testing a script that i'll be using on an unattended Windows DVD.

The System has Windows XP SP3 Home on it, 640MB RAM.

Cryptographic service disabled/corrupt?

.cat files deleted?

There can be other reasons...

Thanks, that fixed it. The first solution to rename edb.log worked just fine. My drivers are showing up as signed correctly again.
