Windows Scheduled Task: What are the minimum user rights needed for the task?

  • 772

At the moment, I have task that is configured to run as user "automatictask"

But the task will not run, "unable to start" is shown.

When I add this user to the Administrators group, then the task runs fine.

But in real life.... I want this user to be SUPER restricted.... ONLY able to run this task, no login rights, no file system rights other than to the one batch file....

I have searched high and low for a document that says "here is the most stripped down, basic user that can run a task" ....

There seems to be no such document!

Suggestions?

Thanks!

    Other than the filesystem permissions, you'll need to allow Log on as a batch job. It controls allowing the session to be created for a scheduled task.

    The task scheduler should put the user in that allow list when you create the task. You can confirm with the Local Security Policy tool. The other possibility is that it's configured through group policy, in which case, do some digging in the resultant set of policy and find the GPO that needs changed.

    Here's the other thing: Check out the permissions on c:\windows\system32\cmd.exe. They're funky. If you've removed the user from the Users group, it can't run cmd.exe by default, which tends to be a big part of running a batch file. Add the user to that ACL, with read/execute. Check any and all executables the batch file needs to touch.

  2. How about granting the following Policies:

    • Allow log on locally
    • Act as part of the operating system
    • Adjust memory quotas for aprocess
    • Bypass traverse checking
    • Lock Pages in memory
    • Log in as a batch job
    • Log in as a service
    • Perform volume maintenance tasks
    • Replace a process level token
