The gist is to ensure that the account is a member of the IIS_WPG group on the local machine. Then start the application pool.

To be sure, run this command:

aspnet_regiis -ga MachineName\AccountName

as this document states:

Also, don't forget to create an SPN for the account:

 

setspn -A MSSQLSvc/ databaseservername.fullyqualifieddomainname

domain\customAccountName
