after sysprep system keeps rebooting found new hardware

[surfertje]

After i run sysprep and the system reboots for the first time the administrator is automatically logs in. Then the system finds new hardware and wants to reboot. He keeps doiing that, after six times i take a look at the device manager and see that all hardware is detected, there are no yellow marks in front of any hardware.

How can it be that the system keeps automatically logging in all the time and keep finding new hardware?

In sysprep i have the option: auto logoncount 2 times.

That the administrator logs in automatically is resolved thru the user account sceen, setting the option that the user must use a username and password. But this is before sysprep the normal setting and after sysprep the setting is changed.
