The Server Operators group must have the ability to schedule jobs by means of the AT command disabled.
Overview

| Description |
|---|
| This policy controls the ability of members of the local Server Operators group to schedule AT jobs. If disabled, only administrators can schedule jobs that use AT commands. Unlike Scheduled Tasks which require you to specify the credential under which the task will run, AT jobs run under the authority of whatever account the AT service runs (SYSTEM by default). Non administrators who can schedule AT commands, thus have a means to elevate their privileges. Although this setting is disabled, Server Operators will still be able to schedule jobs using Task Scheduler. |
