Windows – avoiding console window display when scheduled task runs batch file

What about just putting the batch file in the computer's Startup folder? I can't remember the specifics, but I think the Scheduled Tasks runs under a different context than the Desktop (logged-on user). By putting the batch file in the computer's Startup folder, it will be running under the context of the logged-on user.

Follow the below steps to troubleshoot and resolve your problem

Task Scheduler Properties. . .

From Windows Task Scheduler on the job properties (see bottom most screen shots) in the. . .

• 1. General tab, ensure that the below options are select/checked or unchecked just as shown in Print Screen A

  • Uncheck Run only when user is logged on
  • Check Run whether user is logged on or not
  • Check Run with the highest privileges

• 2. Conditions tab, ensure that the below options are select, checked, or unchecked just as shown in Print Screen B

  • Check Wake the computer to run this task

• 3. Actions tab, click Edit, and enure that the Start in (optional) is set just as shown in the below example (DO NOT put double quote marks around it) for the full path pointing where the batch script is located WITHOUT a final backslash "\" Print Screen C

SECURITY CONSIDERATIONS

• Once you press OK (2. above) it should prompt you for the credential to run this as, and that credential is what will need access to EXECUTE the batch file where it exist, and it will also need access to do whatever the batch file is running that you scripted out.

• It may be best to setup a static service/proxy user account for this process and then use its credentials to run the process. You'd need to ensure its password is strong and it set to never expire—and it needs access to EXECUTE the batch and run whatever the batch scripted process is running and any commands and resources, ect. it utilizes as well.

• It seems the option Run whether user is logged on or not you MUST check the option Run with highest privileges for it to actually run as expected from the Task Scheduler.

Error Checking

• If there is an issue with the actual batch script but the Windows Task Scheduler actually does execute it to run it but the batch script logic errors out, etc. for whatever reason, the Task Scheduler may not see this failure at this level. From its perspective (by default most of the time), it’s executing the batch file so as long as it can execute it and has access to do so, its job is done successfully.

• Add error checking or logging to the batch script logic to catch (or troubleshoot) issues at this level including ensuring that the security context which the batch scheduler executes it as has appropriate access to commands, resources, etc. which the batch script runs as.

Group Policy Considerations

CHECK GROUP POLICY AND LOG ON AS A BATCH JOB PERMISSIONS

Answer: On Windows, this privilege is granted through the Local or Domain Security Policy. To do this using the Local Security Policy, follow these steps.

1. In the Control Panel, open Administrative Tools, then Local Security Policy.
2. Beneath Security Settings, open Local Policies and highlight User Rights Assignment.
3. Locate Log on as a batch job. Open the properties and add any users that need this right.
4. When finished, save your changes and close the Local Security Settings window.

Your changes should take effect immediately. To make changes to the Domain Security Policy, on a domain controller, use the Domain Security Policy utility in the Control Panel

Batch Script Logic with Mapped Drives or Full UNC Path, and issues. . .

If your script is referencing a mapped network drive but you want it to Run whether the user is logged on or not, then under this context, the drive mapping may not actually be there for the batch process to do what’s expected.

If possible, use UNC paths in your batch script logic rather than a mapped drive letter to avoid issues. Otherwise, you may need to use PUSHD \\ServerName\ShareName at the beginning of the batch process and then use POPD at the end of the batch process. You could map the drive with NET USE X: \\ServerName\ShareName at the beginning of the batch process and then disconnect the drive with NET USE X: /DELETE at the end of the batch process.

• NET USE
• PUSHD
• POPD

WinSCP Batch Script Examples

Below are two very basic and dumbed-down examples of an FTP script to upload to and an FTP script to download from an FTP server using WinSCP.com. Be sure the SET winscplogin= variable is set to the name of the FTP connection you have defined from within the WinSCP GUI.

This way builds the script dynamically and you build the FTP commands from within the batch script but you can also just simply point it to a static WinSCP script with the FTP commands in them otherwise too which is easy to setup.

Upload to an FTP Server

@ECHO ON

SET logfile=C:\folder\path\log.log

::SET WinSCP variables, etc.
SET prgwinscp="C:\Program Files\WinSCP3\WinSCP.com"
SET winscplogin="ABC Company"
SET winscpfile=C:\folder\path\ABCompany_FTP_OUT_WinSCP.txt
IF EXIST "%winscpfile%" DEL /Q /F "%winscpfile%"

:ftpout
ECHO.                                              >> "%logfile%"
ECHO *******************FTP OUT******************* >> "%logfile%"
ECHO Delivering file(s) to ABC Company FTP server  >> "%logfile%"
SET ftpdir="ToABC"
ECHO option batch on           >> %winscpfile%
ECHO option confirm off        >> %winscpfile%
ECHO option transfer binary    >> %winscpfile%
ECHO open %winscplogin%        >> %winscpfile%
ECHO cd %ftpdir%               >> %winscpfile%

Custom Example Scripts

Be sure to use both the options of Run whether user is logged on or not and Run with the highest privileges when you schedule the batch script. Once you apply these changes you will need to put in credentials to run the task as explicitly. Be sure to use an account that has execute access to the C:\Program Files (x86)\WinSCP\WinSCP.com file and that also meets the other general prerequisites as listed above.

If you still have issues and want to confirm it's not OS security related, create a new local account on the machine and give it a strong password, set it to never expire, and to have the run as batch permissions. You can also make it a local admin and test just to be thorough to see if giving the account local admin access on the machine makes any difference.

This would mean you have two files: a batch script and a WinSCP. The batch script will pass the WinSCP script to WinSCP.com and you can just execute it to run the process. Be sure this script works as the same user while logged on by simply executing it to test and then test with that same account while logged onto the machine session with the Run only when user is logged on option to confirm it works from Task Scheduler as well before you set it to run whether logged on or not, etc.

The Task Scheduler Actions tab will only use the Program/Script: field with all other fields left blank but the Program/Script: field will have a value of C:\folder\path\yourbatchscript.cmd.
