When installing VS2003, the SOS help document will also be installed in the directory Program Files \ Microsoft Visual Studio. NET 2003 \ SDK \ v1.1 \ Tool Developers Guide \ Samples \ sos; however, this help document does not appear to be installed in VS2005. For more details, see http://msdn2.microsoft.com/en-us/library/ms954594.aspx .... I put these two documents on my cnblogs, which can be downloaded from here (http://files.cnblogs.com/happyhippy/sos.rar.
