PXE Client Reboots After Booting In WinPE

I came across this issue several time while working on OS Deployment with ConfigMgr 2007.

Symptoms:
Clients boots in to PXE, contact the SUP server ,get WinPE image, boot in to WinPE with SCCM screen and then it reboots after couple of minutes. No error message thrown.

Cause : The most like cause is that the network driver (Vista OS) for that particular model of computerhas not been injucted in to the boot image.

Resolution: Find the correct Windows Vista network driver for the target computer and injuct the driver in to boot image.
