Thank you for your answer and suggestions. I'll do that. To make the storie worst the Winpe MUST be x64 since we want to instal W2k3 x64 To answer your question, no the network card just shows up as etwork card, nothing else either in x86 or x64 version What's really annoy me is that we have the same behaviour on a vmware virtual machine with AMD lan card which shouldn't be a problem. Tomorrow we'll try to do the same on Virtual Servers Just in case. To be franc I really have the feeling gthat I am missing to do something but I am not able to find what !! I am just wondering if we need a unattended file for the wpinit. Do you use one ? We the hardware we use is a Dell 1950 with sas raid HBA, Qlogic Card for the san et Broadcom card BCM5708S NetXtreme II. No problem at all with all these devices, except the lan The virtual machine is a VM from VMware WKS 6.0 configured as a WinXp station (meaning using amd Lan Card) I'll keep you informed of any progress
