This is more of a memory post for me to remember locations of important KB items, the source for this info is Server: Microsoft-IIS/7.0\r\n
Some info on how to use this great new utility from Microsoft called DebugDiag (or IIS Diagnostics), I have already used this on at least two occasions to locate problems with IIS hangs, and to find places to improve performance, some of the information that this tool gives can not be found any other way - and is a great timesaver- like showing exactly what files are included in an ASP file (include tree).
