Windows Task Scheduler reports incorrect/inconsistent result code

Question:

<strong>Background:</strong> I am attempting to get email notification upon failure of a scheduled task. My task can indicate failure via exit code (errorlevel) and I want to use that and follow the filter approach described in <a href="https://stackoverflow.com/a/4289360/29805" rel="nofollow">this answer</a> to trigger an email.

<strong>Problem:</strong> I am getting inconsistent behavior from Task Scheduler on different machines and versions of Windows. To test, I'm using the following very simple task.

<ul><li>Run only when user is logged on. (where "user" is the current user)</li> <li>Action: Start a program <ul><li>Program/script: cmd</li> <li>Arguments: /c "exit /b 1"</li> <li>Start in: blank</li> </ul></li> <li>Everything else: default</li> </ul>

I've enabled Task History, and when I manually run the task on both Windows 7 Ultimate and Windows Server 2008 R2 Enterprise, a correct history item like the following is created in category "Action completed":

<blockquote>

Task Scheduler successfully completed task "\test" , instance "{abcdefgh-fab0-4a21-b51a-e25baaaa0000}" , action "C:\Windows\system32\cmd.EXE" with return code 1.

</blockquote>

The text in the <em>Last Run Result</em> column corresponds to this: (0x1).

However, when run on Windows Server 2012 (Azure VM), the following erroneous message appears:

<blockquote>

Task Scheduler successfully completed task "\test" , instance "{abcdefgh-fab0-4a21-b51a-e25bbbbb1111}" , action "C:\Windows\system32\cmd.EXE" <strong>with return code 0</strong>.

</blockquote>

(Emphasis mine.) However the text in the <em>Last Run Result</em> column reads: Incorrect function: (0x80070001). This indicates that at least part of the Task Scheduling processor recognizes some degree of error condition. If I replace the arguments with /c "exit /b 0", this column reads: The operation completed successfully. (0x0)

I've tried various combinations of values for user context, "start in" directory, arguments (with and without /b), and different operating systems under "Configure for:", to no avail.

<strong>Question:</strong> How can I get Task Scheduler on the Windows 2012 machine to display the correct return code in the history item?

<strong>Workaround:</strong> While I still want to understand this bizarre behavior (perhaps it indicates some more significant problem/misunderstanding), I am solving my original issue by adding the following to my task script:

$objMailMessage = New-Object System.Net.Mail.MailMessage $objMailMessage.From = "username@gmail.com" $objMailMessage.To.Add("recipient@example.com") $objMailMessage.Subject = "The task failed." #$objMailMessage.Body = "Detailed information." $smtp = new-object Net.Mail.SmtpClient("smtp.gmail.com", 587) $smtp.EnableSsl = $true $smtp.Credentials = new-object Net.NetworkCredential("username@gmail.com","pass") $smtp.send($objMailMessage)

Answer1:

I'm seeing a similar issue on Server 2012 with a batch file that looks like it succeeds, shows a return value of 0 in event log, but a Last Run Result of 0x80070001.

I see MSFT has a hotfix available for Server 2012 which might address this issue:
