I've just changed the account that BE uses to do the backup, and have renamed the BEWINUI.UNI file to BEWINUI.OLD as instructed. All services restart normally, but then when I try to open the Veritas user interface the application hangs just after the "initializing user interface" phase. It is the Job Engine service that is actually hanging (bengine.exe), and if I terminate that process in Task Manager I can get into the program, and the backup will run, but I get errors saying "There is not enough disk space available to write the on-disk catalogs." If I give the backup user account Admin rights it seems to work... is that really necessary?
