Automated Import of PowerShell SCCM Module

While writing quite a few PowerShell scripts for SCCM, I got tired of having to look up the location of the SCCM PowerShell module to import. I decided while writing the current PowerShell SCCM script, I would automate this process from now on. This makes it a snap using SAPIEN's PowerShell Studio to make this function a snippet and quickly add it each time I write a new SCCM script.

This script allows you to import the SCCM module without having to look up the location. The only parameter you have to specify is the -SCCMServer, which is the name of the SCCM server. The script will then connect to the SCCM server, get the parent installation directory, including the drive letter, and then search for the ConfigurationManager.psd1 file. If it finds more than one file, it will import the latest one.

You can use the function in this script in other scripts to make the process a breeze.

The script can be downloaded from my GitHub repository.

           Imports the SCCM PowerShell Module  
           This function will import the SCCM PowerShell module without the need of knowing the location. The only thing that needs to be specified is the name of the SCCM server.
