Office Web Apps

Published: May 16, 2012

Alert Name:   PowerPoint high rate of "No Available Server" errors

Event ID:   No event ID

Summary:   With Microsoft PowerPoint Web App, Microsoft SharePoint 2010 Products users can view and modify their presentations by using a Web browser. A high rate of "No Available Server" responses to editing requests may mean there are issues with the application server, or that PowerPoint Web App is unable to serve all user requests.

Symptoms:   One or more of the following symptoms might appear:

  • Users who use PowerPoint Web App to edit documents experience very poor performance.

  • Users who use PowerPoint Web App are unable to edit documents because they do not receive responses from the application server.

Cause:   One or more of the following might be the cause:

  • The application server is malfunctioning.

  • There are not enough PowerPoint Web App editing worker processes.

  • There are not enough application servers.

Resolution:   Increase the maximum number of worker processes

  1. Verify that you meet the following minimum requirements: See Add-SPShellAdmin.

  2. On the Start menu, click All Programs.

  3. Click Microsoft SharePoint 2010 Products.

  4. Click SharePoint 2010 Management Shell.

  5. At the Windows PowerShell command prompt, type the following command:

    Set-SPPowerPointServiceApplication -Identity <ID> –EditingWorkerProcessCount <N>
    

    Where:

    • <ID> is the name or ID of the PowerPoint Web App service application.

    • <N> is the number of editor worker processes.

For more information, see Set-SPPowerPointServiceApplication.

Resolution:   Reset Internet Information Services on all front-end Web servers

  1. At the command prompt, type the following command, and then press ENTER:

    iisreset

Resolution:   Add another server to the farm

  1. If this failure keeps occurring even after you have followed the steps in all other resolutions, you should add a server to the farm to help load-balance the workload.
