Since installing the October update for Windows 11 24H2 we have users across the domain having login issues. Sometimes making nearly 20 attempts to log into the domain before it being successful.
I have seen an article about this being the case if there are cloned machines on the network with identical SIDs. However we don't deployed cloned devices and although we do deploy images via SCCM, I have followed this article: https://dori-uw-1.kuma-moon.com/en-us/troubleshoot/windows-server/active-directory/ntdsutil-find-clean-duplicate-security-identifiers and verified that no duplicate SID's exist in our domain.

2025-11-10T16:06:02.17+00:00 Hi Daniel Kaliel,
I think the last resort is to access the official Microsoft Support for Business contact portal at this URL: https://support.microsoft.com/en-us/contactus/
This is the central hub for all business product support. Once on the page, you will be guided through a few steps to get the specific contact details for your issue.
Get support options. The website will then present you with the most up-to-date contact methods for your region, which often includes a direct phone number for commercial support.
I think this kind of support would facilitate you more easily, as it is a live chat that provides you with simultaneous consultancy.
If you find this information helpful to some extent, please accept the answer so that it could be spread further to those in need. Thank you and good luck :)
