I'm trying to inject the downloadable form of SP1 (sp1network.exe - 80something meg) into Windows 2000 Professional OEM. Is this possible? Whenever I use update.exe to try to do it, it tells me not all the neccisary files are present. Anyone have ideas? Do I need the retail version of win2kpro to do this? How do I use Windows 2000 service pack slipstreaming?
