Event Details

Product: Internet Information Services
ID: 1300
Source: Microsoft-Windows-IIS-IISManager
Version: 7.0
Message: An unexpected error happened while processing a service request.


Check a custom WMSvc client

If you are using a custom client to connect to the Web Management Service, you may receive a 401 response. This behavior may occur if the client does not authenticate before it tries to call Web service methods through the management service.

Possible resolutions include the following:

  • Contact the vendor of the client about the error. The vendor should have more specific knowledge about the features and behavior of the client program.
  • Check the event log message for a specific error number that may provide additional clues about the failure. This error number will be different from the Event ID. To do this, see the steps below.

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

To check for a specific error number:

  1. In the Event Viewer, select the event that you received.
  2. Click the Details tab, then Friendly View.
  3. If a specific error number is available, the words Binary data: should appear.
  4. Below In Words, note the number after the colon.
