The application pool account used by Central Administration has update permissions on all Windows SharePoint Services components within the farm, and should not be the same account used for any other content web application.Central Administration application pool account should be unique and it is on my test server and we are using sharePoint 3.0. can you please tell me how to solve this tasks, i am very new to share point.
