The WebClient service allows Win32 applications to access documents on the Internet. The service extends the network capability of Windows; it allows standard Win32 applications to create, read, and write files on Internet file servers through the use of WebDAV, a file-access protocol that is described in XML and uses HTTP for communication. Because it uses standard HTTP, WebDAV runs over existing Internet infrastructure, such as firewalls and routers. The WebClient service is installed on both Windows XP and Windows Server 2003. On Windows XP, the service starts automatically. On Windows Server 2003, the service is disabled. If the WebClient service stops, users of the computer will not be able to use the Web Publishing Wizard to publish data to Internet locations that use the WebDAV protocol.
