Hello Marek Thanks for your reply.
I read this article: https://www.zdnet.com/article/windows-11-24h2-bug-list-updated-one-fixed-12-to-go/ In section 6 there are mentioned some major problems in networking and obtaining IP addresses. I suspect this could be related to your problem. After reading the article I was afraid to do the upgrade so I do not have any 24H2 update until now, so I am not able to confirm the behavior. I any of the machines in the network gets the update I will check for you to confirm.
Well, could be related. The Microsoft community discussion linked is very long but mainly seem to complain about IPv4 connectivity where I never faced issues. But of course it might be related as the issues seem to be network stack related.
I noticed these renewal-loop all the way back in November I think and it's still there whenever I set up a fresh Windows. While I am personally almost entirely moving away from Windows I see this issue becoming a potential problem in larger scale office networks as soon as they move/upgrade to Windows 11 24H2. Specifically as we move towards the EoL of Windows 10 in October 2025.
I agree that this is likely not a kea issue at all but I was hoping to confirm if anybody else seeing the same issues and if there is ways to work-around it (e.g. setting specific DHCP options for Windows 11 24H2).
Darren already replied with some mitigations. They don't prevent the problem but perhaps help in case of large-scale rollout of 24H2 causing significant load-increase on DHCP and DDNS.
