I'm running DPM 2007 ver2 beta2 on a Windows 2003 Standard Server with Service Pack 2. I'm attempting to back up to an IBM Ultrium 3583 Tape Library. I can see the tapes and inventory them fine. When I attempt to backup to a tape I get the following error: An unexpected error occrured during job execution. (ID 104 Details: Access Denied (0x80070005) Has anyone else run into this issue?
