Microsoft Security Update KB5006067 October 2021

Question

Hi - this update has caused issues on all of my servers running IIS - I am getting errors on all servers "A process serving application pool " " suffered a fatal communication error with the Windows Process Activation Service. The Process ID was "7504".

When I removed this update, the error is fixed and we can then access our IIS web server portals.

I have had to disable automatic updates as this update keeps reinstalling and wonder if you could let me know if Microsoft will be releasing a fix for this issue.

regards,

Irene Heffernan
