Yep, looks like this will be the way I'll follow. Rob, many thanks for your help!

Mighty all, Does anyone know if there is a command line parameter for the "schtasks /create" command, which would enable the "run task as soon as possible after a scheduled start is missed" option? Many thanks in advance, Alex

As a suggestion, when I've come across missing parameters for this I've made a task manually with the properties I want, exported to XML and then I create the task with something like this: schtasks /create /TN "My New Task Name" /xml "C:\TEMP\My Saved Task.xml" /RU DOMAIN\username /RP password
