My work has asked if the upcoming implementation of KB5004442—Manage changes for Windows DCOM Server Security Feature Bypass (CVE-2021-26414) - Microsoft Support will affect Domino servers running on Windows Server 2019. I can't find anything online detailing if Domino server is included in the authenticated applications.

Hi Stephen,

Domino server does not use DCOM, so it is not affected by the DCOM server vulnerability (CVE-2021-26414).
