PowerShell Remote sessions and scope question: Commands appear to run locally

Question

Here's a sample script that attempts to create a remote session on a server, then use WMI to get a list of the server's IIS application pools, and list their names: ``` function Test-Remoting { [CmdletBinding()] param ( ) begin { Enter-PSSession TestServer $appPools = Get-WmiObject -namespace "root\MicrosoftIISv2" -class "IIsApplicationPool" -Authentication 6 $appPools | ForEach-Object { $appPool = $_; $appPool.Name } Exit-PSSession } } ``` This function is contained in a file called "Test-Remoting.ps1." I open up PowerShell, CD into the directory that contains this file, dot-source the file in, and call the function: ``` PS C:\Users\moskie> . .\Test-Remoting.ps1 PS C:\Users\moskie> Test-Remoting ``` But the result of this script is a list of the application pools on my local machine, and not TestServer. Alternatively, if I run the following lines (identical to the ones in the function) manually at the PowerShell prompt, I do get the list of app pools on the remote server: ``` PS C:\U…

Accepted Answer

I believe Enter/Exit-PSSession is meant more interactive use. From the Enter-PSSession help:

```
SYNOPSIS
    Starts an interactive session with a remote computer.
```

In a script, use New-PSSession and Invoke-Command like so:

```
$session = New-PSSession server01
Invoke-Command -Session $session {hostname}
Remove-PSSession -Session $session
```

Update: To execute a complete script remotely use the FilePath parameter on Invoke-Command:

```
icm server01 -FilePath C:\users\keith\myscript.ps1 -arg 1,2
```

This will copy the script to the remote computer server01 and execute it there with the supplied parameters.
