How to delete Application Pools in SharePoint 2010

 

When creating a new service application for Powerpivot an errormessage showed up;

Error: An object of the type Microsoft.SharePoint.Administration.SPIisWebServiceApplicationPool named “PowerPivot Services AppPool” already exists under the parent

Within IIS no such Application pool existed, what to do?

There were 5 powerpivot App pools created because of my 5 attempts to create the Service application

You can delete the application pool using PowerShell!

• Open the SharePoint 2010 Management Shell with administrator privileges
  • Start ->All Programs -> Microsoft SharePoint 2010 Products -> Right click on SharePoint 2010 Management Shell ->Run as administrator
• Run ‘Get-SPServiceApplicationPool’
• Run ‘Get-SPServiceApplicationPool -Identity [Name of the application pool]‘
• Run ‘Remove-SPServiceApplicationPool’
  • Enter the Identity => this is the name of the application pool
  • Enter ‘Y’ to delete the application pool

You can now recreate the service application using the same names you used before
