How to: Determine Whether the Web Site for Team Foundation Server Has Been Extended
If the Web site for Team Foundation Server has been extended in SharePoint Products and Technologies, the following errors might appear when you use Team Explorer:
TF31002: Unable to connect.
TF30331: Cannot connect to the Team Foundation Server.
TF31001: Team Foundation cannot retrieve the list of team projects. The request failed with HTTP status 404.
You should not extend the Web site for Team Foundation Server because that change will interfere with correct functioning of the site. If the Web site has been extended, you must unextend it. For information about how to unextend a Web site, see How to: Unextend the Team Foundation Server Web Site.
The process varies based on what version of SharePoint Products and Technologies you are using.
