I have received question about availability of Sxstrace for Windows XP and Windows Server 2003.
Unfortunately this is not possible. The traces from sxstrace.exe really comes from Sxs.dll. Sxstrace simply tells sxs.dll when to trace, where to log, and then parse the log to a humanly readable form. In order for sxstrace to work in Windows XP and Windows Server 2003, traces have to be added to sxs.dll in those versions. unfortunately at this tage of the life cytle of XP and Server 2003, it is very difficult to make any change to sxs.dll.
Hey, maybe this give you a good reason to upgrade to Vista:)
