How to: Verify or Correct the Status of Web Service Extensions

  • Article

If you have problems when you access a Web site or Web service, you should verify that all required Web service extensions are allowed. Web service extensions are Internet Server Application Programming Interfaces (ISAPIs) and common gateway interfaces (CGIs) that extend Internet Information Services (IIS) functionality beyond serving static pages.

Note

If you installed SharePoint Products and Technologies on a server other than the application-tier server for Team Foundation, verify that all required Web service extensions are allowed on both servers.

Required Permissions

To perform this procedure, you must be a member of the Administrators security group on the application-tier server and on the server that hosts SharePoint Products and Technologies.

To verify or change the status of a Web service extension in IIS 6.0

  1. Log on to the server.

  2. Click Start, point to Administrative Tools, and then click Internet Information Services (IIS) Manager.

    Internet Information Services (IIS) Manager opens.

  3. In the tree pane, expand the node for the local computer, and click Web Service Extensions.

    The status of each extension appears in the results pane.

  4. Verify that the following extensions are set to Allowed:

    • ASP.NET v2.0.50727

    • Windows SharePoint Services or Windows SharePoint Services V3

  5. If the status is set to Prohibited, right-click the name of the extension, and click Allow.

  6. Close Internet Information Services (IIS) Manager.

To verify or change the status of a Web service extension in IIS 7.0

  1. Log on to the server.

    Internet Information Services (IIS) Manager opens.

  3. In the Connections pane, click the server node.

  4. In the Features View pane, double-click ISAPI and CGI Restrictions.
