Resolve

Correct WMSvc client-server authentication

You may be unable to log on to the Web Management Service (WMSvc) if invalid credentials are supplied, if you are not authorized to perform the action attempted, or if some other intermediate issue is preventing authentication.

Possible resolutions include the following:

  • Ensure you log on with valid credentials.
  • Ensure that you are authorized for the area to which you are trying to connect.
  • If a provider failed to instantiate, verify that the provider type is correct, and that the assembly that contains the module provider is installed in the Global Assembly Cache (GAC).
  • HTTP 401 errors can have many causes. For more information, see the Knowledge Base article Troubleshooting HTTP 401 errors in IIS.

Verify

To perform this procedure, you must have membership in Administrators, or you must have been delegated the appropriate authority.

To verify that the connection between the Web Management Service and your client can authenticate correctly:

  1. Click Start, click Control Panel, and then click Administrative Tools.
  2. Right-click Internet Information Services (IIS) Manager and select Run as administrator.
  3. Under Connection tasks, Click Connect to a server… The Connect to Server dialog box appears.
  4. Under Server name, select the server name to which you want to connect.
  5. Click Next. If the connection was successful, the message "Created a new connection successfully" will appear on the next dialog box page.
