For remote selections, do not change the logon account information. They rely on the logon account used to connect to the server they reside on, and will ignore the additional logon account you can specify. This applies to drives, Lotus, System State, and Exchange selections (except mailboxes, which can and do use logon accounts).
To change and test a logon account for a resource
While Backup Exec attempts to connect to the resources, "Testing" displays in the Test Results column. After a test has completed, the Test Results column will display one of the following results: Successful, Not tested, or an error message. The Not Tested result indicates that either the logon accounts have not been tested or that the tests have been performed but the server that contains the selection could not be accessed.
