SCEP Defender Troubleshooting

Let’s analyze the options to Fix SCCM SCEP Related Issues. In this post, I will try to cover the knowledge acquired from the field to fix different issues of Windows Defender or Endpoint Protection client (a.k.a SCEP?).

Don’t get confused between SCEP and Windows Defender or Endpoint Protection clients. All these are the same from an IT Professional perspective. Microsoft changed the name of SCEP to Windows Defender or Endpoint Protection client.

In this post, I’m sharing the information for Endpoint protection (defender) clients that are managed through Configuration Manager (a.k.a SCCM). Let me know in the comments section if you have any queries/concerns.

Issue

Endpoint Protection manages antimalware policies and Windows Firewall security for client computers in our Configuration Manager hierarchy. Till here the statement is absolutely correct and SCEP does what it’s supposed to do but there are cases of offenders who refuse to get the regular definition updates from SCCM and make our entire infrastructure itself vulnerable.

We started this SCEP (Windows Defender or Endpoint Protection client) Remediation project early in 2019 and the task was simple. We just had to make sure all the clients in the infrastructure are running the latest definitions if they are connected to the network.

Sounds simple but when we did our hands dirty and started seeing different errors then we saw limited articles and fixes to help us achieve the goal.

There is not much information available on google too apart from the generic MS article https://docs.microsoft.com/en-us/mem/configmgr/protect/deploy-use/troubleshoot-endpoint-client and the one from Henrik Hoe https://blog.ctglobalservices.com/configuration-manager-sccm/heh/configuration-items-and-baselines-example-scep-client-compliance/

So finally we reached home to HTMD : https://forum.howtomanagedevices.com/ and tried.

Important – Read more about the question here: https://forum.howtomanagedevices.com/endpointmanager/configuration-manager/scep-definitions-not-updating-mecm-2002-adr/

If you are done reading the question then you noticed the HOD – Anoop C Nair Suggested opening case with MS because of the complexity of the question.

Note : Most of the points explained in this blog are from several Microsoft forums and the data was collected from those including several other websites like CTGLOBAL (Link already given in the block above) MANAGE ENGINE, COMPARITECH, BERKELEY, SEARCHSECURITY TECH, TRUSTRADIUS, and REDDIT.

So without further delay let’s deep dive from page 1.

Objectives:

  1. The evolution of malware
  2. Overview of System Center Endpoint Protection
  3. Management + Security
  4. Overview of the Endpoint Protection client
1. In 1991, 1000 known threats, in 2001 there were 60,000
2. Today there are millions, and it’s growing every day
3. Sophistication and production rates continue to evolve
4. Anybody can do it—full malware suites available online
5. Your stuff is worth money, and they want it!

  1. Hi Anoop. We have a problem in our environment where around 3k machines are still stuck on the anti malware engine version that’s shipped with 1909. Despite all efforts it’s not updating to latest anti malware version. Have already tried a few solutions posted on technet, but no joy so far. These machines however are up to date with virus definitions. Could you please advise, what are we not doing to fix aforementioned issue?
