Running batch file on Remote Computers using PowerShell 2.0 - powershell

Question

I am trying to run a exe on remote machines which would basically uninstall a product agent. below is the code:
$test = Get-Content PC.txt
foreach ($a in $test)
{
$curr = Get-Location
Set-Location \\$a\Admin$\System32\CCMSetup
.\ccmsetup.exe /uninstall
Set-Location $curr
}
It doesn't work. I ended up removing the program from the host computer itself :)
Alternate Option: I created a batch file with the command line:
cd C:\Windows\System32\ccmsetup
ccmsetup /uninstall
exit
It seems the above can also be achieved using Invoke-Command.
Invoke-Command -ComputerName $client -FilePath UninstallCCM.cmd
Apparently, it does not accept batch file. I would like to keep it as simple as possible.
Currently I am using PSExec for installing and uninstalling the program. Do I need to enable PS Remoting (WinRM) on every remote machine on whom I need to execute scripts using PowerShell?
Can someone please help? Thanks in advance.

Answer 1

This command should execute successfully:
Invoke-Command -ComputerName $client -ScriptBlock { cd C:\Windows\System32\ccmsetup; ccmsetup /uninstall} -Credential $(Get-Credential) -Authentication CredSSP
but you will need to enable CredSSP authentication on all machines by running these two commands on each machine:
Enable-WsManCredSSP -Role Server -Force
Enable-WSManCredSSP -Role Client -DelegateComputer * -Force

I highly recommend downloading PSTools. There is a command in there called "psexec"
PSexec is so simple, you call it like this:
psexec \\myserver C:\Windows\System32\ccmsetup /uninstall
