Non-interactive At.exe tasks do not run in Windows Server 2003 (843280)

SYMPTOMS

After you use the AT tool (At.exe) to schedule a task, the task may not run as you expect. If you view the task with the Scheduled Tasks tool, you may see the following error status in the Status column of the Scheduled Tasks folder:

0x80

Note To start the Scheduled Tasks tool, click Start, point to All Programs, point to Accessories, point to System Tools, and then click Scheduled Tasks

Additionally, the Schedlgu.txt log file may contain an entry that is similar to the following entry: "At2.job" (test.cmd)
Finished date and time
Result: The task completed with an exit code of (80). Note To view the Schedlgu.txt log file, follow these steps:

Click Start, point to All Programs, point to Accessories, point to System Tools, and then click Scheduled Tasks.
On the Scheduled Tasks menu, click Advanced, and then click View Log.

This symptom may occur when all the following conditions are true:

The task is configured not to interact with the desktop. When you use the AT tool to schedule a non-interactive task, the non-interactive task does not use the interactive parameter.
The AT Service account is configured to log on with a user account instead of with the System account.

Note To view the AT Service account, follow these steps:
1. Click Start, point to All Programs, point to Accessories, point to System Tools, and then click Scheduled Tasks.
2. On the Scheduled Tasks menu, click Advanced, and then click AT Service Account.
You connect to the computer with a Terminal Service session. Additionally, the Terminal Service session is logged on as the same user account that is configured for the AT service.
