How to trigger a bat file on remote server only after the pssession is formed on the server

Question

Write-Host "Welcome to Application Process Start/Stop Dashboard" -ForegroundColor Green
Write-Host "`n" "1) Stop" "`n" "2) Start"
[int]$resp = Read-Host "Choose option 1 or 2 for stopping or starting application process respectively"
if($resp -eq 1)
{
[System.Reflection.Assembly]::LoadWithPartialName("System.Windows.Forms")
$result = [System.Windows.Forms.MessageBox]::Show('Are you sure you want to STOP ?', "Info" , 4 )
if ($result -eq 'Yes') 
{
$user = "NAmarshmellow"
$server = "Desktop_10U"
$storesess = New-PSSession -ComputerName $server -Credential $user 
Enter-PSSession -Session $storesess
$path = "\\Users\mellow\Documents\Proj"
$pwd = Read-Host -AsSecureString
$bstr = [System.Runtime.InteropServices.Marshal]::SecureStringToBSTR($pwd)
$value = [System.Runtime.InteropServices.Marshal]::PtrToStringAuto($bstr)
NET USE $path /user:$user $value
Start-Process cmd -ArgumentList "/C C:\Users\Desktop_10U\Documents\Some\Stop.bat" -Wait
Clear-Variable storesess
Exit-PSSession
}
}

I want to trigger a bat file which has some commands that will stop a specific application process. To stop this application process there are specific commands which requires triggering the cmd file on a network drive. So I have written a code which will form PSSession and after the PSSession is formed only then the NET USE command should run. If I first form the PSSession and then trigger the command manually fire the NET USE command then it works fine. But when I trigger the code as a whole it doesn't run fine it throws below error.

NET : System error 1219 has occurred.
At line:18 char:1
+ NET USE $path /user:$user $value
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (System error 1219 has occurred.:String) [], RemoteException
    + FullyQualifiedErrorId : NativeCommandError

Multiple connections to a server or shared resource by the same user, using more than one user name, are not allowed. Disconnect all previous connections to the server or shared 
resource and try again.

The issue is that Enter-PSSession only works via an interactive prompt. aka. You typing in commands into a prompt. A script/running everything together is not interactive (i.e. you can't start entering in commands into the middle of the running script).

The work around is to use Invoke-Command and place everything you want to perform in a script block. This way can be executed as non-interactive commands. e.g.:

....

$user = "NAmarshmellow"
$server = "Desktop_10U"
$path = "\\Users\mellow\Documents\Proj"
$pwd = Read-Host -AsSecureString
$bstr = [System.Runtime.InteropServices.Marshal]::SecureStringToBSTR($pwd)
$value = [System.Runtime.InteropServices.Marshal]::PtrToStringAuto($bstr)

$script = {
    $user = $Using:user
    $path = $Using:path
    $value = $Using:value

    NET USE $path /user:$user $value
    Start-Process cmd -ArgumentList "/C C:\Users\Desktop_10U\Documents\Some\Stop.bat" -Wait
}

Invoke-Command -ComputerName $server -Credential $user -ScriptBlock $script

....

Thank you your solution was apt! – Powershellbud May 28 '20 at 20:43 — Powershellbud, May 28 '20 at 20:43
