Verified all Windows and Dell updates are installed.

VPN fails when all security tools are disabled or uninstalled.

Any advice would be appreciated.

Thank you

    Hi. Thank you for your question and reaching out. I’d be more than happy to help you with your query

    Please be reminded that your local time should be synchronized correctly. This could be the reason why the machine is affected.

    You can also check your firewall setting to make sure that the VPN server from your location is reachable and to make sure that the required port is open.

    If the reply was helpful, please don’t forget to upvote or accept as answer, thank you.

    @Todd Christopher

    Welcome to the Microsoft Q&A Platform. Thank you for reaching out & I hope you are doing well.

    I understand that you are seeing the error message "Server did not respond properly to VPN Control Packets. Session State: Reset Sent" with AAD Authentication in Azure P2S VPN Client.

    Can you please check if the local time is synchronized (correct) in the affected machine?
    If not, make sure the time is updated.

    In case the above did not help,

    • Can you check if the user is able to log in using the same credentials from a different machine?
    • Similarly, please check whether a different set of credentials works in these machine?

    Thanks,
    Kapil.
