I had the following problem : I needed to rerun a program from the sccm distribution share on the server. When you create a scheduled task with schtasks.exe there is no way to configure the working directory for the program to run. The update I wanted to run creates temporary files in the working directory. The permissions on the SCCM distribution share are read-only. So to run the update i needed a different working directory for the scheduled task. The only solution I found until now was create a temporary batch file in the C:\temp of the computer and create a scheduled task for that batch file.

So this scripts creates a temporary batch file on the remote computer and creates a scheduled task for it. Because the schedule is once and the start date is in the past it will be deleted once it has run.
