Hello, 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. Anyway this has nothing to do with kea. Marek Sent with Proton Mail secure email.
