SUMMARY
You can use the Windows 2000 Task Scheduler to make sure that specific programs open, or scripts run at a predetermined time. This is useful for making sure that system utilities or programs run on the computer of a user when you want, without the user having to remember to start the program. This article describes how to prevent users from changing scheduled tasks in Windows 2000.

Prevent Users from Changing Scheduled Tasks
The Windows 2000 Task Scheduler runs in the background. By default Windows 2000 Task Scheduler starts when you start Windows 2000. However, unless you take steps to prevent it, users can change the scheduling of tasks or even delete them. In a highly controlled environment, you may want to prevent users from changing scheduled tasks. To do this:

Set User Account Permissions
Set the advanced permissions on files and folders to deny users permission to view or change a scheduled task. To do this, follow these steps:  Start the Scheduled Tasks utility. To do this, click Start, point to Programs, point to Accessories, point to System Tools, and then click Scheduled Tasks. Right-click the task where you want to configure permissions, and then click Properties. Click the Security tab, and then click Advanced. Click Add, click the user or group that you want to prevent from changing or deleting the scheduled task, and then click OK. Assign the permissions that you want. For example, click to select the following check boxes in the Deny column of the Permissions list:

 Click OK, and then click OK to quit the Access Control Settings for  dialog box (where   is the task that you are modifying).</li> Click Yes to confirm that you want to continue, and then click OK.</li></ol>
