by the looks id say it has no idea what network card you have so the driver isnt there / working
also looks like a boot.wim from vista might be worth trying one from win7
Yes it is a vista boot.wim.
Whats bugging me is that this machine was only imaged about 2 weeks ago with the same boot image and it worked fine.
I know it sounds daft but have you restarted the DHCP Server (IE full on and off) and the same with your WDS box?
Is there any reason why you aren't looking at MDT? It is MUCH easier to get the drivers sorted for!
