Microsoft’s latest Windows update breaks VPNs, and there’s no fix
What Microsoft actually said:
Windows devices might face VPN connection failures after installing the April 2024 security update, or KB5036893.
We are working on a resolution and will provide an update in an upcoming release
I’m so fed up with everyone trying to make a quick buck on our constant struggle to stay safe.
The reality is that it broke "something* in certain lpt2/ipsec connections using certain authentication protocols, although they haven’t yet specified which particular connection technologies are affected.
However this does not mean that a blanket affect of ALL VPN connection not working is an issue.
So far we are unaffected on clients using ipsec and PAP protocol authentication, nor connections using Anyconnect (aka Cisco Secure Connect).
I have also not seen any affect on private VPN clients such as PIA or Nord on machines that have this update.
I suspect what broke was clients using MSChap, Microsoft’s own protocol for authentication for VPN clients.
