To work around this problem, use Task Scheduler to schedule the computer to shut down and restart at a specific time. To do so, follow these steps:

1.	Click Start, and then click Control Panel.
2.	Click Performance and Maintenance, and then click Scheduled Tasks.
3.	Double-click Add Scheduled Task. The Scheduled Task Wizard starts.
4.	Click Next.
5.	Under Click the program you want Windows to run, click Browse.
6.	In the Select Program to Schedule dialog box, locate the %SystemRoot%\System32 folder, locate and click the Shutdown.exe file, and then click Open.
7.	Under Perform this task, specify a name for the task and how frequently you want this task to run, and then click Next.
8.	Under Select the time and day you want this task to start, specify a start time and date for the task, and then click Next.
9.	Type the user name and password to run this task under, and then click Next.
10.	Click to select the Open advanced properties for this task when I click FinishFinish. check box, and then click
11.	Click the Task tab.
12.	In the Run box, specify any additional parameters that you want to use with Shutdown.exe.
13.	Click OK.

Alternatively, you can change the account used by the at command, as follows:

1.	Open the Scheduled Tasks folder as described earlier in the "Workaround" section.
2.	On the Advanced menu, click At Service Account.
3.	Type the required account name and password, and then click OK.

Notes

•	This change will affect all tasks scheduled with the at command, not just Shutdown.exe.
•	The account used must have the SeRemoteShutdownPrivilege right on the local system.
