If I install sccm 2007 SP2 -> R3 and complete the basic configuration and then add SUP role (need install WSUS) and OSD (need install WSD) later, is it ok? Or should I install WSUS and WSD before installing sccm? Thanks in advance.

Yes. WDS and WSUS are pre-requisites for specific site roles that are not initially installed. They should be installed before you add these roles but not necessarily at site installation time. The pre-req checker will squawk about not having the WSUS SDK installed, but its just a warning and not strictly required at install time.Jason | http://myitforum.com/cs2/blogs/jsandys | http://blogs.catapultsystems.com/jsandys/default.aspx | Twitter @JasonSandys
