The RIS server to which you are attempting to post this installation does not contain the correct CD-based image. The version of the CD-based image on the server must match the version of the system you are attempting to image[Version 5.1 Build 2600, Language English]. Please either select a different RIS server to post this installation to or add the corresponding CD-based image to the current RIS server
Now I searched through some other forums and they have suggested that as ntoskrnl.exe has been patched that you need to copy the ntoskrnl.exe from the client machine and replace ntoskrnl.exe in the Windows XP Image on the Windoes 2000 RIS Server, some have suggested that you can't riprep machines that have had the updates applied any help will appreciated.
