We still have over 1,000 Windows XP machines. We are rolling out Windows 7 workstations but it will take a few months before XP is gone. For broadcast messages to all systems NET SEND is used. this of course went away in Win7 replaced with the command MSG. A tech who's no loner with our company wrote a custom .EXE that when run will prompt you for your "Message" and then NET SEND it out to all workstations. Now that we have about 15% of our company running Win7 this is no longer a usable tool. So I wanted to solve this problem with PowerShell.
I found this code online.
$Comp =
"MG11706"
$msg = "Place your message here"
Invoke-WmiMethod -Path Win32_Process -Name Create -ArgumentList $msg -ComputerName $Comp
My problem with this is you need all machines in a .TXT file that you read and it would take a long time to cycle through it. I don't know the inner workings of NET SEND but it would send the message all all machines within a 15 seconds.
Can PowerShell mimic a NET SEND without reading a .TXT file of machine names? Can it do what NET SEND used too and if so how?
