I am currently running RIS in our environment and it has always worked great but we are now starting to deploy 2008 installs and need to change things. I have read through some documentation but would like to clarify a couple of things. If I setup WDS in mixed mode can I have custom wim files for 2008 and 2003. Keep in mind the server running WDS is 2003 SP2. Does anyone know of a good link to step through the setup process.
