If the logon account needed to restore data is different from the default logon account, you can change the account through the Resource Credentials dialog box. You can also use this dialog box to overwrite logon accounts for redirected restores. You can also verify that a logon account can access a resource.
To change and test resource credentials for restore jobs
On the Properties pane, under Source, click Resource Credentials.
Select the logon account you want to use for this selection, or click New and create a new logon account.
To verify that the logon account you are using can access the resources selected for restore, click Test All.
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
Some tests may take a long time to complete. To cancel a logon account test, click Cancel Test.
