How to run a .ps1 (powershell script) on all domain workstations?

I have a power shell script to display a pop up window (alert message) and it works fine on local Pc or when run from command prompt or powershell itself but I am not able to run/deploy the same using sccm or even usinbg task schedular (GPO).

Is there a way to invoke the powershell script that sits on network share or local workstation onto all domain workstations.

Maybe you're running it bad:

Or just doesn't work.
What you can do is to get the online computers within the subnet, save it into a variable like $computers, and then use a foreach computer in online array running the invoke-command - computer $computer -scriptblock $scriptblockvar -credentials $creds (-asjob -jobname "jobname)
() are optional parameters, the credentials $creds=Get-Credential (or automate it saving username and password within the ps1 file).

You can run it from a centralized computer (like a server and use scheduler, as shown in my article).

Hi .
Below is my script and I do not want to run as startup script or on logon. I would like to push / deploy on demand.
Jose > where would I add the $computers variable and invoke command. Also do I need to provide credentials $creds and where?
Sorry I am new to this.
I appreciate your help.

You can either put that code into a PS1 script on a network resource you can reach from each PC, or  store it into script block like
$script = {
  function New-PopupMessage {
  # and so on
  New-PopupMessage @Params

Open in new window

Then invoke that against all machines:
$cred = Get-Credentials
Get-ADComputer | % {
  invoke-cmd -ComputerName $_.Name -ScriptBlock $script -Credential $cred -AsJob
  # or with a script:
  # invoke-command -ComputerName $_.Name -FilePath '\\server\share\script.ps1' -Credential $cred -AsJob

Open in new window

Since the popup waits for confirmation, you'll have an issue - execution is halted. Hence I used the internal job system, running the popup in a background task. But be aware there is a limit of background tasks running simultanously, so script execution might halt at say 64 PCs, until some popups are confirmed.
We could also use the in-built parallel execution feature of Invoke-Command, but it has the same issue:
$cred = Get-Credentials
invoke-cmd -ComputerName (Get-ADComputer).Name -ScriptBlock $script -Credential $cred -ThrottleLimit 256
# or with a script:
# invoke-cmd -ComputerName (Get-ADComputer).Name -FilePath '\\server\share\script.ps1' -Credential $cred -ThrottleLimit 256

Open in new window

Correct suggestions in this context are #a42412341 and #a42412975.

and what is wrong with #a42412647?
Qlemo"Batchelor", Developer and EE Topic AdvisorCommented:
Shaun, that requires an action by the client (starting the machine or logging in), versus a push as the OP wants (and that can be read from the question, though not 100% clear). The comment #a42412929 (posted later than your comment) clarifies the push requirement.
