I have this script to create a popup on the workstation. However 1) it required elevation to show more than one popup and 2) I need this to run on the server.

Register-ObjectEvent $fsw Created -SourceIdentifier FileCreated -Action {

$name = $Event.SourceEventArgs.Name

$changeType = $Event.SourceEventArgs.ChangeType

$timeStamp = $Event.TimeGenerated

$wshell = New-Object -ComObject Wscript.Shell

$wshell.Popup("The file '$name' was $changeType at $timeStamp",0,"Done",0x1)

#Write-Host "The file '$name' was $changeType at $timeStamp" -fore green

Out-File -FilePath c:\outlog.txt -Append -InputObject "The file '$name' was $changeType at $timeStamp"}

Is it possible to modifiy this so it will send a pop message using the msg.exe command to pre-determined workstations?

If so, any pointers? I'm lost.

Thanks

what isn't working with msg?  I must be missing something because simply inserting

msg /server:$srvr 'message'

will send 'message' to $srvr.  Iterate if you want to send to a list of servers.

No.  Just use MSG at a prompt.

MSG /SERVER:W8test * "hello world"`

Hi not_sure_,

You can also refer to the function Send-NetMessage, which is written by the command msg.exe , you can provide bulk servernames, message and the timeout:

Function Send-NetMessage{ 
<#   
.SYNOPSIS   
    Sends a message to network computers 
  
.DESCRIPTION   
    Allows the administrator to send a message via a pop-up textbox to multiple computers 
  
.EXAMPLE   
    Send-NetMessage "This is a test of the emergency broadcast system.  This is only a test." 
  
    Sends the message to all users on the local computer. 
  
.EXAMPLE   
    Send-NetMessage "Updates start in 15 minutes.  Please log off." -Computername testbox01 -Seconds 30 -VerboseMsg -Wait 
  
    Sends a message to all users on Testbox01 asking them to log off.   
    The popup will appear for 30 seconds and will write verbose messages to the console.  
 
.EXAMPLE 
    ".",$Env:Computername | Send-NetMessage "Fire in the hole!" -Verbose 
     
    Pipes the computernames to Send-NetMessage and sends the message "Fire in the hole!" with verbose output 
     
    VERBOSE: Sending the following message to computers with a 5 delay: Fire in the hole! 
    VERBOSE: Processing . 
    VERBOSE: Processing MyPC01 
    VERBOSE: Message sent. 
     
.EXAMPLE 
    Get-ADComputer -filter * | Send-NetMessage "Updates are being installed tonight. Please log off at EOD." -Seconds 60 
     
    Queries Active Directory for all computers and then notifies all users on those computers of updates.   
    Notification stays for 60 seconds or until user clicks OK.
