On IIS cannot find existing application pool showed in CA

Question

We are using SP2010 on-premise Enterprise edition. It is a single server containing SQL2008 (not express) and SharePoint

Recently we found the User Profile Service application is not working. In the CA > User Profile Service Application it shows "This User Profile Application's connection is currently not available. The Application Pool or User Profile Service may not have been started. Please contact your administrator"

I clicked on Manage Service Application > select User Profile Service Application > Property. It is using an application pool that not existing in IIS. In the dropdownmenu all the pools' name are not existing in IIS. Check with PowerShell Get-SPServiceApplicationPool, it shows the same pools as dropdownmenu. So I choose to create a new pool. It return success message but in IIS no new pool is create! Also the UPSA still returning the same error.

What could be the problem?

Answer 1

The details steps here :

1. Open SharePoint Management Shell as Administrator.

2. Type this command

   Get-SPServiceApplicationPool | select Id, Name
   

3. Open IIS Manager > Application Pool > Match Application Pool GUID with the command result.

Refer Get the corresponding SharePoint services name of the Application Pool Guid

Answer 2

I am so stupid. I forgot in SP2010, application pools created by CA or PowerShell are named with GUID. Hence when I open IIS manager I cannot find the new pools I created because they are named (e.g. 7caf285b-df15-91fgf-95a8-ca74edbddc01)

Refer to this old post, I use Get-SPServiceApplicationPool | select Id, Name to get the GUID of pools and match the names.
