Driver Load error in Non Admin user account

I have written a driver, it works fine in Administrator account on Win XP. But my final product is to run on non admin account. I am running it on non adm开发者_如何学Cin account for testing. But driver is not able to load. CreateFile() function returns error no 6. which means INVALID_HANDLE. Please reply ASAP.

You cannot load new drivers as a non-administrator on Windows XP.
