![]() 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. ![]() 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).

When the Configuration Manager administrator connects remotely to client computers, the same issue (under any user account, the remote connection fails, but the local connection is successful) occurs for Configuration Manager tools like Support Center or Policy Spy.Ĭontent fails to be distributed to a remote distribution point.Įrror codes that are recorded in the respective log files or client applications may resemble the following: Error codeįor example, when the administrator tries to open a console remotely, the SmsAdminUI.log file displays the following error message: However, under the same credential, a local connection to the SMS Provider is successful. The Configuration Manager console fails to access the SMS Provider remotely under any user account. SymptomsĪfter installing the June 2022 security updates for Windows or later, a Configuration Manager administrator encounters one of the following issues: This article provides solutions for issues that may occur in Configuration Manager after the June 2022 security updates for Windows are installed. With the June 2022 security updates for Windows, hardening changes in DCOM are enabled by default. Microsoft Endpoint Configuration Manager uses the Distributed Component Object Model (DCOM) Remote Protocol at multiple parts of functionality. The modification can cause interoperability issues between networked devices, so if you were disabling it up until now to bypass issues, now might be the time to work towards a more permanent solution.Applies to: Configuration Manager (current branch) Knowing about this mandatory change and catering to it is important, especially for enterprise customers. Now, after the course of almost two years, DCOM hardening changes will become enabled by default from Ma(Patch Tuesday), and there will be no option to disable them. In November 2022, it had to issue some updates to cater to customer feedback. Then in June 2022, Microsoft rolled out updates to enable it by default with the option to disable it. ![]() In the first phase of DCOM hardening during June 2021, it was disabled by default and you had to enable it using Windows Registry keys. Since the disclosure of this vulnerability, Microsoft has been making changes to DCOM in order to harden it, and the company has now issued a reminder that these configuration modifications will become mandatory in less than a month. For those unaware, DCOM leverages remote procedure calls (RPCs) to expose application components to facilitate communication between networked devices. Back in June 2021, Microsoft revealed details about the CVE-2021-26414 vulnerability that could exploit the Distributed Component Object Model (DCOM) remote protocol.
