ClientDiag.exe for troubleshooting WSUS

There is a great tool from Microsoft to troubleshoot SUS installations from the client. From my experience it tells you fairly quickly where the problem lies.
Download from this location with the Readme. These are linked (at the moment) from the wsus support page which also contains a link to the server version of this tool (which I’ve not tried yet)
A good set of results can be found in the extended entry.
