I recently purchased the AS/400 client agent for Arcserve Backup Version 12. I have followed the brief instructions on how to install the client agent on the AS/400 system, which seems to be installed and running correctly. I have then gone in to the management console to create a new backup job or modify an existing job, right clicked the as400 systems heading and added a new machine filled in the hostname and ip address, then went to expand the machine and it asked for an username & password. I have tried every admin level username/password I can think of that is setup on the as/400, but everytime it returns an error "failed to login to the agent".
