Powershell – pass paramter to Schtasks

You could run it silently using a Windows Script file instead. The Run Method allows you running a script in invisible mode. Create a .vbs file like this one

Dim WinScriptHost
Set WinScriptHost = CreateObject("WScript.Shell")
WinScriptHost.Run Chr(34) & "C:\Scheduled Jobs\mybat.bat" & Chr(34), 0
Set WinScriptHost = Nothing

and schedule it. The second argument in this example sets the window style. 0 means "hide the window."

Complete syntax of the Run method:

 object.Run(strCommand, [intWindowStyle], [bWaitOnReturn])

Arguments:

• object: WshShell object.
• strCommand: String value indicating the command line you want to run. You must include any parameters you want to pass to the executable file.
• intWindowStyle: Optional. Integer value indicating the appearance of the program's window. Note that not all programs make use of this information.
• bWaitOnReturn: Optional. Boolean value indicating whether the script should wait for the program to finish executing before continuing to the next statement in your script. If set to true, script execution halts until the program finishes, and Run returns any error code returned by the program. If set to false (the default), the Run method returns immediately after starting the program, automatically returning 0 (not to be interpreted as an error code).

Try psexec'ing into the server as the user and running the batch file. You will then likely see the error.

I had a similar problem with batch file running normally but not with 08 R2 Task Scheduler. It would run if "Only run when user logged in", but not when "Run whether user is logged on or not".

Turned out something was trying to access drives by drive letter. I'm not sure if this was programmed directly or 08 was trying to be smart and converting the UNC path to a mapped drive. My ini file for the program only had UNC paths though. Obviously drive letters aren't mapped when user not logged on..

I ended up having to map the drive in the batch file with credentials (it doesn't pass through). It then worked.

This may or may not be a similar issue to you.
