I am having the exact same problem as JMRAMOS. My issue is with 2 different Dell laptops D500/505 that have Intel Pro 100 VE cards. WinPE detects it as a generic "Ethernet Controller" thus networking "fails" although I can do the commands above and still get network connectivety. Boy if anyone know how to fix this please do tell as I have been beating my head for a couple of days now on this and am at my wits end! Thanks!
