Signed Driver in WinXP but not Win2K? Please help!

[greatx]

I have a signed driver for a webcam that when installed on WinXP it
does NOT popup any dialogs telling me about it being unsigned, and
under the driver properties it shows as a publisher "Microsoft Windows
Hardware Compatibility Publisher", and signed of course.

Now if I install the same driver under Win2K, it pops up the message
telling "The software you are about to install does not contain a
Microsoft digital signature.".

I ran sigverif.exe on WinXP and Win2K to check is the driver is signed.
On both, sigverif.exe said the driver was signed. So why is Win2K
complaining about it on the driver installation process then??

Are there drivers that are certified and signed only for WinXP but not
for Win2K?

It could be that the driver is not signed for that version of windows. If
the product works then I wouldn't sweat it other contact the company that
manufactured that product.

Since your problem is within Win2k, post to a newsgroup for that OS. Here
is a list of MS public newsgroups.

Thank you. I just posted it in the Win2000 area as well.

But basically the question is: can there be drivers signed only for one
of the OSs and not bot both?
