When i run the Powershell script below i receive the error below. How do i run programs through powershell with parameters? The script will be a group policy logon.

Invoke-Expression : A positional parameter cannot be found that
accepts argument '\TBHSERVER\NETLOGON\BGInfo\BGIFILE.bgi /timer:0 /s
ilent /nolicprompt '. At

$LogonPath = $env:LOGONSERVER + "\NETLOGON\BGInfo\Bginfo.exe" 
$ArguList = $env:LOGONSERVER + '\NETLOGON\BGInfo\BGIFILE.bgi /timer:0 /silent /nolicprompt '

Invoke-Command is best suited for running commands remotely. As Shay points out you can use the ampersand & to tell PowerShell to execute something locally just like the cmd.exe shell.

In order to make Invoke-Command work you would need to do something like this:

$program = "C:\windows\system32\ping.exe"
$programArgs = "localhost", "-n", 1
Invoke-Command -ScriptBlock { & $program $programArgs }

Notice the use of the the ampersand in the script block. So if you are running a command locally just use the ampersand as Shay's example shows.
