    Hi,

    Everytime when we need to reboot the system we need to send an email to the users that are logged on the servers. It happened a lot that users don't read mail and because of that, they never log off. To prevent data loss, is there a way to send message via powershell so that message pop-up on the screen?

    (Get-ADComputer -SearchBase "OU=Computers,DC=domain,DC=com" -Filter *).Name | Foreach-Object {Invoke-Command -ComputerName $_ {msg * "Please close all open files. The Server will be shut down in 5 Minutes"}}

    Use PowerShell to run it in a loop with a list of computers.

    Since you are not a PowerShell scripter then you can just put 10 lines in a batch file with the message and one computer per line.

    Why would he do that? Did you check my command? With that command you can send message to all servers in an OU.

    (Get-ADComputer -SearchBase "OU=Computers,DC=domain,DC=com" -Filter *).Name | Foreach-Object {Invoke-Command -ComputerName $_ {msg * "Your message"}}

    No one seems to know how to read the instructions:

    No need for any kind of remoting.  Just use MSG. 

    MSG   {username | sessionname | sessionid | @filename | *}
         [/SERVER:servername] [/TIME:seconds] [/V]   [/W] [message]

    It is critical to learn how to read instructions if you want to be a technician or scripter.

    How can you send msg to all computers in OU (If we have 10 computers in OU -like RDS Session hosts) with this?

    Why do you think you need Invoke-Command. MSG remotes without that.  It will just make the whole script much more prone t failure and assumes the user knows how t use PowerShell when it is clear that he doesn't.

    It usually always best to use the simplest methods in scripting, programming or any technology.

    Hi,

    I agree with jrv when he said "simplest is often the best", but sometimes you have to do things more complex. In my case I couldn't use msg.exe method remoting for company reasons. But I can use powershell so you can still do this (I didn't copy the Get-ADcomputer ... jrv already did that):

    Invoke-WmiMethod -Class Win32_Process -Name Create -ArgumentList "C:\Windows\System32\msg.exe * 'you_message'"
    Hope it helps. (I used it in a workflow and it works very well)

    The key of learning is practice.

    It is not possible to block the MSG port as it is the SMB port.  I don't think this is a case.  Only Admins can use MSG.  If the program was blocked it would not work with WMI or wit remoting so I doubt that it is disallowed.

    You're right, but it is a political reason, not technical. We have to use Powershell if we want to make any remoting operation.

    I agree with you Arnaud and msg cannot be used in my example.
