Zeezam, I would like some more information on how you resolved your issue. I am experiencing the same exact error message, when trying to deploy an image down to my MSI GT638R laptop. The image is Windows 7 Home Premium and I only have Win7 32/64 bit drivers that are downloadable from the vendor web site. However, neither of these driver sets "wpeutil InitializeNetwork" successfully and obtain and IP Address from my DHCP server. I googled drivers and found some standard RealTek PCIe Windows Vista drivers off the RealTek web site that appeared to have initialized and grabbed an IP address, however, when I inject these drivers into my boot.wim, I still continue to receive the same error. I am stomped and would like your assistance, since you were able to resolve the issue. Can you contact me via e-mail at xxx to troubleshoot more with what you were successful with? Thanks in Advance!
