Modifier les mots de passe des pools d’applications Web (Office SharePoint Server)

Mise à jour : 2007-04-19

Use this procedure to change the password for the application pool identity. The application pool is the context in which the Web application runs and the identity is the account under which the application pool runs. The application pool stores the identity account’s credential information and will continue to function even after the password has expired. However, if the application pool is restarted, the stored credential information is lost, and the application pool cannot be started until the credential information is updated.

If the application pool cannot start, a "Service Unavailable" HTTP error will be displayed to the users of any Web pages or services that the Web application provides.

Remarque :
These procedures can be performed only after the password has been changed on the domain controller. The credentials entered are checked against those on the domain controller. If you enter the new password before the password has been changed on the domain controller, an error will result and the settings will not be changed.

Remarque :
To save the changes, you must restart the application pool. This will cause the content or services that that the Web application provides to be momentarily unavailable while the application pool restarts.

Remarque :
This procedure needs to be run only on the server that is running the SharePoint Central Administration Web site.

Important :
Membership in the Administrators group on the local computer, or equivalent, is required to complete the following procedures. Membership in the Farm Administrators group (WSS_RESTRICTED_WPG Windows security group) is not sufficient to complete these procedures.
