Security News > 2022 > June > Recent Windows Server updates break VPN, RDP, RRAS connections
This month's Windows Server updates are causing a wide range of issues, including VPN and RDP connectivity problems on servers with Routing and Remote Access Service enabled.
One of the more severe problems is the servers freezing for several minutes after a client connects to the RRAS server with SSTP. Windows Remote Desktop and VPN connectivity issues.
The vast majority of reports related to these problems coming in since Patch Tuesday have a common theme: losing Remote Desktop and VPN connectivity to servers with Routing and Remote Access Service enabled where the June Windows Server Updates have been installed.
"What I saw after the June updates were installed was that no TCP connections established from either the client-side or the server-side would ever get up and running. I couldn't do a basic RDP session into the server either," one admin told BleepingComputer.
Multiple other admins have also reported on Reddit and in comments to BleepingComputer stories that they're having issues with LLTP/SSTP VPN clients and RDP failing to connect after deploying the June Windows Server updates.
This month's Windows updates may also cause backup issues on Windows Server systems, with some apps failing to backup data using Volume Shadow Copy Service.
