"Unable to forward requests to another media server"

The Issue is generally seen when the Backup Exec configuration is migrated from previous to a new Backup Exec Server. It may happen that the previous device information may still be present in Backup Exec Database Device table.
Remove the previous Backup Exec server or device entry from device table of Backup Exec Database (BEDB).
Note:Please contact Veritas Technical Support for assistance resolving this issue. A Backup of the Backup Exec Database is recommended before making any changes in the BEDB.
