The error is triggered by routing issues between Backup Exec server and the ESX server.


Verify the network card drivers, firmware and the latest version for the Media Server, Storage Array, and ESX Server (If Storage Array is attached to ESX, then just ESX)

Also check if the Backup Exec server is on a different VLAN than the ESX server if it is , move the Backup Exec server to the same VLAN as the ESX server.
