Azure VPN issues - RasMan service - Unknown state

Azure VPN Client stopped working after KB5065813 update – RasMan service Unknown state

 

 

Environment details:

  • Azure VPN Client version: 4.0.4.0 (Microsoft Store)
  • Windows version: Windows 11 Pro, 23H2 (fully updated)

 

Issue Summary: The Azure VPN Client worked fine from Friday (14 November 2025) until Sunday (16 November 2025). On Sunday, Windows installed updates, and starting Monday morning (17 November 2025), Azure VPN stopped working.

When I run the Prerequisites Test in Azure VPN Client, everything passes except:

Rasman Windows Service Status
Result: Unknown state. Please make sure Rasman windows service is in a running state.

However, sRasMan service it's running

 

Registry keys for RasMan exist, and Svchost\netsvcs includes RasMan

What changed: I noticed that the update KB5065813 seems to be causing the issue. This KB is installed on my machine, but my colleagues have KB5041655 instead. As part of troubleshooting, I even changed my laptop to a brand-new device with a fresh OS install, and the issue persists after KB5065813 is applied.

 

What I’ve tried:

  • Restarted RasAuto and dependencies
  • Reinstalled Azure VPN Client
  • Installed older versions of Azure VPN
  • Changed my laptop with a brand new one and a fresh OS install

Questions:

 

  • Is KB5065813 confirmed to break Azure VPN Client functionality?
  • Is this related to the October 2025 RasMan vulnerability patch (CVE-2025-59230)?
  • Any official Microsoft steps or scripts to fix this?

Screenshots attached for reference.

    Hi, Thank you for your reply. Yesterday i just reinstalled my OS and Azure VPN worked until requested windows and defender updates were installed and machine rebooted. Currently i am having the exact same issues. My machine it's from work and it's Intune managed. So i cannot test with 25H2 OS version.  I just discovered that my Defender updates are newer than the ones of one of my colleague and AZURE VPN is working on his machine . Both we are currently up to date and have the exact same version of OS built.
    I have attached the OS built version and my update history VS my colleague update history.

      Hi,

      Thank you for your reply. Yesterday I reinstalled my OS and Azure VPN worked until the requested Windows and Defender updates were installed and the machine rebooted. Currently, I am having the exact same issues. My machine is from work and is Intune-managed, so I cannot test with the 25H2 OS version

      I just discovered that my Defender updates are newer than those of one of my colleagues, and Azure VPN is working on his machine. Both of us are currently up to date and have the exact same OS build version.

      I have attached the OS build version and my update history versus my colleague's update history below:
