Thanks for the response.
This seems to work, but partly in my case.
The thing is: zennoposter (opened with task scheduler) can't view files which are located on my nas server...it gives the error: "run directory the username or password is incorrect"
Though, when I manually open projectmaker next to it, zennoposter (opened by task scheduler) suddenly does view the content of the nas server...
Anyone knows what the problem could be?
