Stack Overflow
Thanks first of all for reviewing this.
I've basically got a third-party agent software which allows me to execute PowerShell as LocalSystem. This allows me to easily run remote PowerShell commands without WinRM etc.
The problem that i'm running into is that on some servers i'm not able to perform get-WindowsFeature or Add-WindowsFeature.
An example of how i'm trying to achieve this is here:
Import-Module ServerManager;
Get-WindowsFeature;
The output is as such:
The term 'Get-WindowsFeature' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.
If I type those same commands into a PowerShell window, or call PowerShell.exe directly, it returns. I'm trying to figure out what we're not doing right within the application, but i'm the most familiar person with PowerShell here.
Is there something special I need to do to load those cmdlets? Get-Module doesn't show anything, oddly.
Thank you!

I also noticed that GCM | ? { $_.ModuleName -eq 'ServerManager' } returns nothing when I run it through there, but through a normal PS window it returns a command list as expected.
This is probably because the PowerShell script is being launched from a 32 bit instance of PowerShell. The ServerManager commands are only available from 64 bit version of PowerShell. See: Can't access ServerManager module via PowerShell
--Edit - To add to jbsmith's comments---
Extra things to try:
When you ran the Get-Command cmdlt:
gcm | ? { $_.ModuleName -eq 'ServerManager' }
It will return nothing because the ServerManager module has not been loaded.
Try running this instead. It will list all available modules to load:
Get-Module -ListAvailable | ? { $_.Name -eq 'ServerManager' }
The other thing to try is to use the "Force" option (Re-imports a module and its members, even if the module or its members have an access mode of read-only):
Import-Module ServerManager -Force;
Get-WindowsFeature;
Issue ended up being that the metadata for ServerManager was 3.0 on these servers, yet the developed exe for calling PowerShell commands was only version 2.0. When it tried to import the modules, schema errors about the metadata were returned, but the EXE didn't redirect them to stdout, hence no response.
Import-Module : The 'C:Windowssystem32WindowsPowerShellv1.0ModulesServerM

e members that are not valid ('HelpInfoUri', 'RootModule'), then try to import
the module again.
