This step applies only if the account used as the identity of the new application pool differs from the account that was used for the identity of the default (MSSharePointPortalAppPool) application pool and you are running a shared services configuration.

You must grant search access to the application pool identity account. In the parent server farm, do the following:

1. On the SharePoint Portal Server Central Administration for Server_Name page, in the Component Configuration section, click Manage shared services for the server farm.
2. On the Manage Shared Services page, in the Direct Access to Search Service section, enter the name of the new application pool identity account in the format DOMAIN\user_name.
3. Click OK.
