I have a vbscript script that I runs fine when I am running it myself.
For some reason, when I run it under the task scheduler as an administration user, it runs, but do
I had the same problem.
I fixed it by using relative path ("logs\log") instead of the absolute I was using before ("U:\workingDirectory\logs\log").
Aparently when you execute scripts via task scheduler you need to use relative paths.
