During installation of a SharePoint 2007 farm, I created a web application to
host the farm's Shared Services Provider. During creation of the web app, I
created a new application pool for it. Later, I realize that I mis-named the
application pool. As there is no option to rename an app pool, I saved it's
config to a file and created a properly named app pool based on the config
file. Then I reassigned the mis-named app pool's web app to the new app
pool. When I tried to clean up by deleting the original mis-named app pool,
I get...

You cannot delete an application pool that contains applications. You need
to reassign all applications in this application pool to another applicatin
pool or delete the applications."

Can anyone tell me why I can't delete the original app pool even when I
reassigned it's contains web apps to a new app pool? Is it a permissions
thing?

Thanks.
