I have had similar problems and tracked it down to media sense. Have a look at - How to disable the Media Sensing feature for TCP&#47IP in Windows It can be weird and affect som machines and not others

We have a large number of Dell Optiplex 360 machines to install over several sites. Machine has a Broadcom Gigabit Ethernet adapter. When trying to create a RIS image the dreaded "The operating system image you selected does not contain the necessary drivers for your network adapter. Try selecting a different operating system image. If the problem persists, contact your administrator. Setup cannot continue. Press any key to exit." message appeared. No matter which driver files (From Dell 0r Broadcom) were put into the $OEM$ or i386 folder and tweaks to inf files as per Broadcom Ethernet FAQs, could not get RIS to work. Eventualy tracked down; Broadcom.com - NetXtreme II 1 Gigabit Drivers Go down the page to "Windows Remote Installation Service (RIS) Drivers" and download the appropriate Windows 2000 / 2003 Ris zip file. (zip file for Server 2003 attached) There is a readme for Server 2000. Unzip the 2 files and put them in the i386 folder. Run - net stop / start binlsvc. Voila - RIS deploys OS. win_xp_2k3_32-11.7.2.zip
