Cause

Windows Servers with the IPv6 network protocol disabled may have an extra network interface named Tunnel adapter Teredo Tunneling Pseudo-Interface that periodically appears and then disappears. If Backup Exec selects the interface as an internal connection to perform deduplication processes during the backup, network connection errors can occur if the interface disappears.

Solution

Disable the Teredo Tunneling Pseudo-Interface on the Windows Server.

1. At the command prompt, type the following:
   
   netsh interface teredo set state disable
    
2. For backups, run the backup job again and for restore, try the restore browse again.
