While trying to delete a sharepoint web application, I received the following error:

An object of the type Microsoft.SharePoint.Administration.SPIisWebsiteUnprovisioningJobDefinition named "Unprovisioning SharePoint - 80" already exists under the parent Microsoft.SharePoint.Administration.SPWebService named "".  Rename your object or delete the existing object.

Very little available information about this error, but what appears to have happened is that because this is the second time I've tried to delete this web application, and I had the same name for each, it is unable to create the unprovision job since it already exists.

To fix, I did the following:

Go to
Central Administration --> Monitoring --> Check Job Status
Click Job Definitions under timer links on the left
Delete the job with the name in quotes (i.e. 'Unprovisioning SharePoint - 80')

You should now be able to delete the web application.

Thanks - wasted an hour on this before I found your note - worked first time, no reboot.
