Here is what I'm trying to do (Add trigger to scheduled task on remote machine):

Invoke-Command -ComputerName BETA -ScriptBlock {Set-ScheduledTask -TaskPath '\Monitor\' -TaskNam
e 'Off' -Trigger (New-ScheduledTaskTrigger -At 16:40 -Once)}

which results into:

Method "NewTriggerByOnce" not found
    + CategoryInfo          : ObjectNotFound: (PS_ScheduledTask:Root/Microsoft/...S_ScheduledTask) [New-ScheduledTaskT
   rigger], CimException
    + FullyQualifiedErrorId : HRESULT 0x80041002,New-ScheduledTaskTrigger
    + PSComputerName        : BETA

Cannot validate argument on parameter 'Trigger'. The argument is null or empty. Provide an argument that is not null or
 empty, and then try the command again.
    + CategoryInfo          : InvalidData: (:) [Set-ScheduledTask], ParameterBindingValidationException
    + FullyQualifiedErrorId : ParameterArgumentValidationError,Set-ScheduledTask
    + PSComputerName        : BETA

wondering may be someone have same issue?

What version of Windows and PowerShell are you using on the local and remote machines?

I've reproduced your error on a windows 10 machine
PS> New-ScheduledTaskTrigger -At 16:40 -Once
New-ScheduledTaskTrigger : Method "NewTriggerByOnce" not found
At line:1 char:1
+ New-ScheduledTaskTrigger -At 16:40 -Once
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : ObjectNotFound: (PS_ScheduledTask:Root/Microsoft/...S_ScheduledTask) [New-ScheduledTaskT
rigger], CimException
+ FullyQualifiedErrorId : HRESULT 0x80041002,New-ScheduledTaskTrigger

Using the production preview of WMF 5.0 on Windows Server 2012 R2 command works and I can create the trigger.

I've also found a difference between the commands on the 2 versions of PowerShell.

I'll investigate this further. Something isn't right somewhere

Oh, it seems that you are right, I just have tried that script from home laptop to work pc all works (both have Windows 10) but machine that I was tried before have Windows 10 Insider Preview, so probably there is some kind of regression, hope that it will not happen later on in normal Windows 10
