I am trying to find some information on the WebClient Service specifically the registry options. I have been unable to find anything other then some specific KB articles about registry settings that solve specific issues. What would be really great is a comprehensive list of all registry settings for all OS services. The Microsoft Registry guide for windows Server 2003 doesn't list the WebClient service at all. Is there anyone who could give me a hint about where I might find this information?
