Why can't I launch an mdb file form Scheduled Tasks in XP or Vista?
Presumably because you're doing it wrong.
The command line should be something resembling (all on one line)
"C:\Program Files\Microsoft Office\Office11\msaccess.exe"
"E:\SomePath\yourdatabase.mdb" /wrkgrp "E:\SomePath\yourdatabase.mdw" /userid
Batchjob /pwd BatchPasswordOnly /x Startupmacro
