This blog post is mainly for us Exchange support engineers but I like to surface things externally because it’s easier to search and link to. This blog post is heavily inspired by http://blogs.technet.com/b/mikelag/archive/2008/08/22/how-to-enable-store-pfd-tracing-upon-reboot.aspx.
With Exchange 2007 and onwards, debug code tracing is logged to the ETW provider GUID 79BB49E6-2A2C-46E4-9167-FA122525D540. When you install Exchange, this ETW provider is registered formally and the GUI ExTRA application works. However, we can still manually do capture an ExTRA trace even if Exchange is not installed; the most common use would be setup issues.
