If you install Microsoft Visual SourceSafe (VSS) 2005 on a computer that is running Windows Vista, you cannot host a VSS Web service.


This behavior occurs because of changes in Microsoft Internet Information Services (IIS) 7.0. IIS 7.0 does not include the WebDAV component. The VSS Web service requires the Put method of the WebDAV component to upload files. Therefore, you cannot host a VSS Web service in Windows Vista.

Note The WebDAV component is an extension of the HTTP protocol. The WebDAV component lets you treat a Web server as a remote server.


To work around this behavior, put the Web service in an IIS virtual folder. For information about how to do this, visit the following Microsoft Developer Network (MSDN) Web site:
