Microsoft Update KB5014805 or KB5014692 from the 6/15/2022 breaks Internet-Connection of Windows Server 2019 when using NAT

Question

I have a network based on a DC and a domain-joined server both running on Server 2019 for 2 years. The domain-joined server has two network cards, one facing the internet and one facing the company's internal network. The traffic of the workstations to the Internet works via the domain-joined server with NAT. Until recently all workstations, the DC and the domain-joined server could communicate with the Internet. Since the Windows update, however, the domain-joined server itself can no longer access the Internet, but the DC and the workstations still can.

The update from 6/15/2022 led to the following concrete problems on the domain-joined server:

1. Boot of the server leads to correct detection of a domain network, but the access type is "No network access".
2. When I restart the NLA service, the domain network changes to an unauthenticated public network, which does not allow the domain-joined server to access the Internet.

I would be grateful for a solution.

Answer 1

Hi there,

The issue you are facing might be due to KB5014697. According to the official Microsoft Windows 11 update KB5014697 is preventing the Wi-Fi hotspot feature from working correctly on some PCs. Some systems running the update will lose internet connection when acting as a hot-spot host for other devices and this might also affect your Windows Server.

The best solution may be to uninstall the update altogether until there’s a proper fix for this issue.
Microsoft is currently working on a permanent solution but meanwhile is offering the following temporary fix: "To mitigate the issue and restore internet access on the host device, you can disable the Wi-Fi hotspot feature"

I uninstalled both updates, everything is fine again. I should contact Microsoft but am too busy for the moment.
