An overview of the different ways to mitigate the impact of DCOM hardening

Microsoft has been tightening DCOM security since 2021 in a staged approach, starting with 'harmless warning' and progressing to 'hard lockdown without manual override'. In many cases, they have provided mitigations to soften the blow. But there are some edge cases where you're essentially still screwed. In this article, I will explain the entire issue, which mitigations are in place, and which things you can do if you're unlucky enough to have this problem land in your lap.

I am a former professional software developer (now a system admin) with an interest in everything that is about making hardware work. In the course of my work, I have programmed device drivers and services on Windows and linux.

I have written firmware for embedded devices in C and assembly language, and have designed and implemented real-time applications for testing of satellite payload equipment.

Generally, finding out how to interface hardware with software is my hobby and job.
