SCCM Inactive Systems Report

I have wanted a PowerShell script that would generate an excel report listing all of the inactive systems, if they are in active directory, and the last time someone logged onto the system if it is in AD. As we all know, it is easy to overlook these systems and they can accumulate, even if the cleanup is setup in SCCM. I chose to use SCCM as the definitive report because it pulls it's initial listing of systems from AD. This script has to be executed on the SCCM server.

I have the script require two parameters: 1) OutputFile and 2) Path. The output file is the name of the CSV file and the Path is the location for the script to write the CSV file to. I have prepopulated the OutputFile parameter, but you can change that if necessary.

The next thing will be that you will need to find your collection ID of your Client Activity: Inactive collection and update that on line 40. If you do not have this collection, you will need to create a collection listing all inactive systems and use the collection ID assigned to it.

Now find out where ConfigurationManager.psd1 is located on your SCCM server and update line 94 with the full path to the module.

The SCCM server needs the PowerShell active directory module feature enabled for this script to function. It is located under RSAT in the Windows Features.

Finally, you will need to execute this script on the SCCM server. I have not found any way around this. I have this script setup in Microsoft Orchestrator that uses PSEXEC.EXE to execute the PowerShell script locally on the SCCM server on a weekly basis. It works flawlessly. Again, this script is running in my company's environment, which will largely differ from others. You will need to modify this script to get it to work in your environment.

You can download the script from here.

16:                             on the SCCM server. You will also need to find the location
