After working out how to see the tape, my login credentials now appear to be incorrect for restoring the files.
My problem may be that the domain on both servers is the same, although they are in no way connected. If someone could confirm this, that would be great.
I have tried to set up the Administrator as a new user, with the same password as the liive box, however I can't get passed the Resource Credentials tab, as the test always fails.
Also the process appears to be trying to restore the file back to a server with the same name, but the secondary server has a differerent name.
