hmm then u should imaging ur windows after installation is done install all the feathers and revlite it but i did that once with desktop exper and windows search all works good even i remove the winsxs and the pending.xml but i cant be sure that is the case with .NET 3.5 Case 2: if winsxs is preserved Everything is ok, I can install .net 3.5, but adding features is still not functioning. try use ocsetup not server manager btw check my topic win server 2008 u might find it useful
