SCCM Lab

Props!

Shout out to Zach Stein (@synzack21) for collaborating to create the Ludus SCCM Ansible collection!

This guide will create a Configuration Manager environment and install Configuration Manager agents on multiple endpoints. For more information, see the blog post by Zach Stein (@synzack21).

  1. Add the synzack.ludus_sccm collection to your Ludus server
ludus ansible collection add synzack.ludus_sccm
  1. Modify your ludus config to add the appropriate SCCM roles to servers.
caution
  • Due to unknown issues with SCCM, .local domain suffixes will not work properly. We recommend using something else such as .domain or .lab for your domain suffix
  • If you wish to add client push to the DC, you will need to enable Remote Scheduled Tasks Management firewall rules or use the disable_firewall role
  • At this time, all 4 site server roles are needed to deploy SCCM, there is no standalone option yet
  • All SCCM VM hostnames MUST be 15 characters or less

ludus range config set -f config.yml
  1. Deploy the range
ludus range deploy
# Wait for the range to successfully deploy
# You can watch the logs with `ludus range logs -f`
# Or check the status with `ludus range status`
tip

If you'd like to watch the progress of the SCCM install, open a console or RDP into the sccm-sitesrv VM and run:

Get-Content C:\ConfigMgrSetup.log -Wait

This will "tail" the log file as SCCM installs.

  1. Use Misconfiguration Manager to explore all the ways to pwn SCCM!

Our favorite SCCM tools are SharpSCCM by @_Mayyhem and SCCMHunter by @garrfoster.

The main way to access SCCM is on the Site Server (sccm-sitesrv) with the Configuration Manager Console.

tip

Using the configuration above, the domainadmin user is the user that has permissions in SCCM. To access the Configuration Manager Console. Log into the sccm-sitesrv VM as domainadmin (which should be the user that automatically logs in to the Site Server).
