I am trying to create a task in task scheduler using Powershell.
$PSVersionTable.PSVersion Major Minor Build Revision ----- ----- ----- -------- 3 0 -1 -1
OS: Windows Server 2012
Here's the script for reference:
Set-Location c:\automation
# Remove IP of host on which this script is going to run
$hostname = hostname
$private_ip = (Test-Connection $hostname -count 1).IPv4Address.IPAddressToString
(get-content .\sch_task_action.conf) | foreach-object {$_ -replace "and not net $private_ip", ""} | set-content .\sch_task_action_final.conf
# Create task schedular
$sch_task_action = Get-Content c:\automation\sch_task_action_final.conf -Raw
$sch_task_principal = New-ScheduledTaskPrincipal -UserId "LOCALSERVICE" -LogonType ServiceAccount
$sch_task_settings = New-ScheduledTaskSettingsSet -ExecutionTimeLimit (New-TimeSpan -Days 7)
$trigger = New-ScheduledTaskTrigger -AtStartup
Register-ScheduledTask -Action $sch_task_action -Trigger $trigger -Principal $sch_task_principal -Settings $sch_task_settings -TaskName "Monitoring"
Content of sch_task_action.conf
:
New-ScheduledTaskAction -Execute c:\windump\windump.exe –Argument "-i 1 -q -w e:\network-dump\Network-Traces.txt -n -C 100 -W 100 -U -n ip and not net 125.14.93.7 and not net 10.0.2.4"
When I try to run the PowerShell script, I'm getting the following error:
Register-ScheduledTask : Cannot process argument transformation on parameter 'Action'. Cannot convert value "New-ScheduledTaskAction -Execute C:\windump\windump.exe –Argument "-i 1 -q -w E:\network-dump\Network-Traces.txt -n -C 100 -W 100 -U -n ip and not net 125.14.93.7 and not net 10.0.2.4" " to type "Microsoft.Management.Infrastructure.CimInstance[]". Error: "Cannot convert value "New-ScheduledTaskAction -Execute C:\windump\windump.exe –Argument "-i 1 -q -w E:\network-dump\Network-Traces.txt -n -C 100 -W 100 -U -n ip and not net 125.14.93.7 and not net 10.0.2.4" " to type "Microsoft.Management.Infrastructure.CimInstance". Error: "Specified argument was out of the range of valid values. Parameter name: className"" At C:\Automation\windump\win_dump.ps1:26 char:32 + Register-ScheduledTask -Action $sch_task_action -Trigger $trigger -Principal $sc ... + ~~~~~~~~~~~~~~~~ + CategoryInfo : InvalidData: (:) [Register-ScheduledTask], ParameterBindingArgumentTransformationException + FullyQualifiedErrorId : ParameterArgumentTransformationError,Register-ScheduledTask
Note: In the script, if I pass the content of sch_task_action_final.conf
(which has the selected IP removed) directly to the variable (as shown below) without reading the file using Get-Content
, then the script works fine and task gets created in the scheduler.
$sch_task_action = New-ScheduledTaskAction -Execute c:\windump\windump.exe –Argument "-i 1 -q -w e:\network-dump\Network-Traces.txt -n -C 100 -W 100 -U -n ip and not net 125.14.93.7"
I've spent few hours trying to figure out by searching online but to no avail.
