A daily scheduled backup will get a message that Backup MyPC can't start because it is already running. When a scheduled backup starts, sbewin.exe shows as a process in Task Mgr, and normally will stop when the backup is completed, but randomly (seemingly) stays open after a successful backup with verification. When it is stopped in Task Mgr, the next day's backup will be succesful. This is running on a WinXP sp2 workstation in an active directory domain (SBServer 2003) and backing up files from the server to tape. This has happened at 2 different offices with essentially the same equipment and setup.
