Please raise the activation authentication level at least to RPC_C_AUTHN_LEVEL_PKT_INTEGRITY in client application. The server-side authentication level policy does not allow the user %1\%2 SID (%3) from address %4 to activate DCOM server. The following time-correlated events should mention Configuration Manager applications and the usernames they're running under:

To log these events, install at least the October 2021 Cumulative Update for Windows. For more information, see the "New DCOM error events" section in KB5004442. To verify the DCOM hardening issue, check the following Event IDs in the System event logs on the server and client computers.

By this point, you must resolve any compatibility issues with the hardening changes and applications in your environment.įor more information, see KB5004442-Manage changes for Windows DCOM Server Security Feature Bypass (CVE-2021-26414).
Hardening changes enabled by default with no ability to disable them. Hardening changes enabled by default but with the ability to disable them using a registry key. Hardening changes disabled by default but with the ability to enable them using a registry key. See the following timeline: Update release Therefore, Microsoft addressed this vulnerability with a phased approach, which is configurable by the RequireIntegrityActivationAuthenticationLevel registry key.

However, some applications require a code change to comply with the new security level. Later, Microsoft released security updates that improved DCOM protocol hardening. In 2021, the Windows DCOM Server Security Feature Bypass vulnerability was discovered and released in CVE-2021-26414.
#DCOM STARTUP TIME REGISTRY VALUE UPGRADE#
The latest versions of Configuration Manager make security changes, so we recommend that you upgrade to Configuration Manager, version 2203 or a later version. Besides enhancing security, installing the update can ensure the same level of DCOM hardening and logging capabilities. To resolve these issues, install the latest cumulative update for Windows on both computers that initiate the connection (the remote console or site server) and receive it (the SMS Provider, distribution point, or remote client).
