Unable to execute EXE remotely using Powershell - powershell

There is an exe file on backup server “Backupsrv” C:\Program files\Veritas\NetBackup\bin\admincmd\bpdbjobs.exe.
When I run this exe on “Backupsrv” using PowerShell it is giving some output on console
& "C:\Program Files\Veritas\netbackup\bin\admincmd\bpdbjobs.exe" -all_columns
Now I tried to run this exe from an application server remotely using Invoke-Command as below.
$result = Invoke-Command -ComputerName "backupsrv" -Credential $cred -ErrorAction Stop -ScriptBlock {
& "C:\Program Files\Veritas\netbackup\bin\admincmd\bpdbjobs.exe" -all_columns
}
No result When executed remotely.
The exe is being executed but not giving any result.

How to run a .bat file in a VM from Powershell

I am trying to parallelize an operation by running .bat files in several remote VMs simultaneously using a Powershell script from a local VM. I can successfully run the .bat file in the local VM by using the following:
Start-Process cmd.exe -ArgumentList $batOptimization_path, $vmNumberParam, $rInstanceParam, $optDataParam, $dataSetParam
The first param in -ArgumentList is the path where the .bat file is located, the rest are command line parameters for the .bat file. To try to run the .bat file on a VM, I am using the following:
$psSession = New-PSSession -ComputerName $script:FsvRConfig.VmList[$i].IpAddress
Invoke-Command -ArgumentList $batOptimization_path, $vmNumberParam, $rInstanceParam, $optDataParam, $dataSetParam `
-Session $psSession `
-ScriptBlock {Start-Job -ScriptBlock { Start-Process cmd.exe -ArgumentList $args[0], $args[1], $args[2], $args[3] -AsJob}} `
-ErrorAction SilentlyContinue
This does not run the .bat files properly. The jobs start and then fail, so obviously this is not the way to launch the jobs. Any advice on getting the .bat files to launch in the remote VMs the way it does in the local VM would be greatly appreciated!

Using PowerShell to execute a remote script that calls a batch file

I am having an issue with running a batch file that is located on a remote server.
I have a batch file located on a remote server that i want to run that kicks off an automated Selenium test. For simplicity, let's say the name of my batch file is mybatch.bat
I have the following code in a Powershell script located on the server:
$BatchFile = "mybatch.bat"
Start-Process -FilePath $BatchFile -Wait -Verb RunAs
If I run this PowerShell script locally on the server in ISE then it runs fine and it kicks off the selenium test which takes a couple minutes to run.
Now I want to try to execute this test from another machine by using PowerShell remoting. Let's assume that remoting is already configured on the servers.
I have a PowerShell script located on another server which has the following code segment. Assume that all of the session variables have the correct information set:
$CMD = "D:\mybatch.bat"
$TargetSession = New-PSSession -ComputerName $FullComputerName -Credential $myCreds -ConfigurationName RemoteExecution
$command = "powershell.exe -File $CMD -Wait"
Invoke-Command -Session $TargetSession -ScriptBlock { $command }
When this script runs, it does connect to the remote machine and create a remote session. It does look like it kicks off the batch file because PowerShell does not give me an error. But it does not wait for the full 3 or 4 minutes for the Selenium test to finish. It seems like it just times out. Also if I am logged onto the other machine, I don't see any Selenium web test running. No Selenium log files or results files are created on remote server as should be expected.
I was wondering what I could be doing wrong with my code.
Also, it seems that the server always returns the echo outputs of the batch file to my local machine. I see these random blinking white screen on ISE which looks like output from the batch file
$command = "powershell.exe -File $CMD -Wait"
Invoke-Command -Session $TargetSession -ScriptBlock { $command }
There are 2 issues with the above code:
$command inside the scriptblock and $command outside the scriptblock are different variables due to different scopes. The variable inside the scriptblock is thus undefined and the scriptblock will simply echo an emtpy value.
Even if $command weren't undefined, the scriptblock would still just echo its value, since it's defined as a string. PowerShell does not execute strings unless you're using something like Invoke-Expression (which you shouldn't).
This should do what you want:
$CMD = "D:\mybatch.bat"
$TargetSession = New-PSSession -ComputerName $FullComputerName -Credential $myCreds -ConfigurationName RemoteExecution
Invoke-Command -Session $TargetSession -ScriptBlock { & $using:CMD }
If you would like execute a bat file from another machine by using PowerShell Remote Session, simply enter dot and then follow by a whitespace, then enter the exact path of bat file located on that remote machine.
Example
Invoke-Command -ComputerName RemoteComputerName -Credential $credential -ScriptBlock {. "D:\Temp\Install_Something.bat"}

Powershell/batch uninstall script works locally but not when using invoke-command

I have a script that installs an .exe with some arguments remotely to a list of servers that works fine. When I try to do almost the exact same thing but run the uninstall.exe that gets installed to C:\Program Files (x86)\ it won't work.
When I run the scripts on the server locally, it kicks off the uninstall. When I try to run the exact same script or command using the powershell invoke-command it won't work.
$serverlist = Get-Content -Path C:\NagiosInstall\test.txt
ForEach ($server in $serverlist) {
New-Item -Path "\\$server\C$\" -Name "NagiosInstall" -Force -ItemType "directory"
Copy C:\NagiosInstall\ncpa-2.1.6.exe \\$server\C$\NagiosInstall\ncpa-2.1.6.exe
Copy C:\NagiosInstall\install.bat \\$server\C$\NagiosInstall\install.bat
invoke-command -ComputerName $server -ScriptBlock {C:\NagiosInstall\install.bat}
Start-Sleep -s 15
invoke-Command -ComputerName $server -ScriptBlock {Remove-Item -LiteralPath "C:\NagiosInstall" -Force -Recurse}
}
The install .bat is just a simple command to silently install that ncpa-2.1.6.exe.
Above is my install script, that part all works fine.
invoke-command -ComputerName $server -ScriptBlock {Start-Process -FilePath "C:\Program Files (x86)\Nagios\NCPA\uninstall.exe" -ArgumentList "/S"}
Running the above command, nothing happens. No errors, nothing.
& "C:\Program Files (x86)\Nagios\NCPA\uninstall.exe" -ArgumentList "/S"
But running the above command in powershell that's running as admin locally on the server and it works just fine.
I've also tried the same approach to create and copy and run a batch file, very similar to the above "install" code. Same thing... nothing happens but if you run the batch locally on the server, it works just fine. I can post this code if anyone is interested.
I'm guessing it has to do with the invoke-command or the fact that it's in C:\Program Files (x86) which might make the syntax different, but I've tried many things and I'm out of ideas besides making an account and posting here.
The issue is that Invoke-Command runs non-interactively, and therefore cannot run as Administrator and respond to a UAC prompt.
The only workaround is to connect to the computer via a PSSession with credentials, and execute it that way:
$Cred = Get-Credential
$Session = New-PSSession -ComputerName $server -Credential $Cred
Invoke-Command -Session $Session -ScriptBlock {Start-Process -FilePath "C:\Program Files (x86)\Nagios\NCPA\uninstall.exe" -ArgumentList "/S"}
$Session | Exit-PSSession
Edit:
The reason that the installer works is that the UAC prompt for Windows Installs is different than anything else in Windows see: How to Silence the UAC Prompt for Per-Machine MSI Packages for Non-Admins or Using Windows Installer with UAC.
Essentially, Windows Installer (already running as admin and UAC approved), is what runs the install on your behalf, and it is Windows Installer and installer settings that determines if you need to see a UAC prompt or not. Hence, this is why the install works. Windows Installer determined that you did not need to see the UAC prompt, and the install proceeds.
Uninstalling is different. Since you are running uninstall.exe, the executable needs admin access and Windows will do UAC before the uninstall.exe even runs.

How to run command line argument using PowerShell script

I am able to install the software from the Windows CMD with the following command
setup.exe -inputFile C:\my_installer_input.txt
However, I want to achieve the same above using the PowerShell script.
I tried same from the PowerShell like this
Start-Process -FilePath "C:\Matlab R2018b\setup.exe" -inputFile "C:\my_installer_input.txt" -ArgumentList "/S
and it fails to run with the obvious reason -inputFile parameter is not available for Start-Process in PowerShell.
PowerShell also runs the native commands directly from PowerShell prompt, which means your command
setup.exe -inputFile C:\my_installer_input.txt
should work directly from the PowerShell prompt.
If you are executing on a remote machine, you can run with Invoke-Command as below.
Invoke-Command -Session $session -ScriptBlock { <YOUR CODE HERE> }
or
Invoke-Command -ComputerName <remote-computername> -ScriptBlock { <YOUR CODE HERE> }
If this is on a remote machine, do something like:
Invoke-Command -Computername ‘x’ -Scriptblock {
Set-Location C:\path\to\file
cmd /c setup.exe /arg1 /arg2
}

Powershell Invoke-command using a file share

I Have power shell script which runs fine when it is located on local computer. if i run test.ps1 file, it executes.
Test.ps1 has a code to use current working directory and reads xml file from current working directory
When i'm trying to use invoke-command and run this script from file share i'm receiving error message unable to find path or so ..
here is my syntax:
Invoke-command -computername "test1" -filepath "\\xyz\test\test.ps1"
above syntax didn't work...
then i tried couple of things like
invoke-command -computername "test1" -scriptblock{\\xyz\test\test.ps1}
and
invoke-command -computername "test1" -scriptblock{(param $x) \\xyz\test\test.ps1} -Argumentlist $scriptroot
None of them worked..
