GroupWise 8.02sp3? (I know!)

I have a restore area setup, and accessible. To my client at least. The POA and restore area are on separate Windows boxes. Will this even work? I have the POA pointed at the restore area, but being windows not sure if the authentication will work. I login to the client, and open backup. I get 8201 error, and a dialog box pointing to the share. I click it, it churns and I see the email I would like to restore, but it gives 8201 when I attempt to. Is my only option to move the restore area local to the POA? This presents a number of challenges. Any thoughts?
