    W10 Pro x_64 v1903 b18362.175


    After having deployed (as admin) Local_Script\BaselineLocalInstall.ps1 -Win10NonDomainJoined on the node and gpupdate /force, respectively rebooted the node, the sandbox's network connectivity is gone.


    I have been pulling me hair to figure out which potential setting from the Security baseline could cause this but without luck and thus here I am hoping to find a solution.

    In order to debug the matter ran RD /S /Q "%WinDir%\System32\GroupPolicy" and thereafter gpupdate /force and the sandbox's connectivity is restored, but of course the GPOs are gone.

    :)

    No internet connection on Windows Sandbox

    Hello bvonr,

    Thank you for writing to Microsoft Community Forums.

    Ideally, if your computer is connected to the internet, even the Sandbox has to be connected. There is no extra setting to turn on/off internet for Sandbox. Few issues regarding network connection on Virtual machines and Sandbox has been resolved
    just by updating to the latest build. Kindly check with the steps listed below and see if it works.

    Method 1: Disable Antivirus software.

    I would suggest you to disable all the security software applications (e.g. Norton, McAfee) that are installed on your host (main) machine. It could be blocking the internet connection, so disable it and see if the issue persists.

    Disclaimer: If you have Windows 10, you’ll get the latest antivirus protection with Windows Defender. When you start up Windows 10 for the first time, Windows Defender is on and actively helping to protect
    your PC by scanning for malware (malicious software), viruses, and security threats. Windows Defender uses real-time protection to scan everything you download or run on your PC. Windows Update downloads updates for Windows Defender automatically to help keep
    your PC safe and protect it from threats.

    If the above suggestions doesn’t fix, kindly check with the method 2.

    Method 2: Disable and enable the Sandbox feature from Control Panel.

    Go to Control Panel >
    Programs
    > Programs and Features > from the left top, select
    Turn Windows features on or off > Scroll down to Sandbox, disable and enable it to check if it works.

    Additionally, you may also refer to the suggestions provided in the article on
    Windows Sandbox has NO Internet when the
    host is connected to a VPN
    .

    Please let us know the results. We are glad to help you further if the issue persists.

    Regards,

    No internet connection on Windows Sandbox

    Thanks so much for the info. I disabled Norton Auto Protect and Smart Firewall and sure enough I had internet on Sandbox. I am questioning why Norton would block the Ethernet adapters in Sandbox though??? Do you know what settings I need to change in Norton
    to allow the Sandbox to work right by any chance. If not don't worry, now that I know what the problem is I will talk to Norton. Again Thanks [sandbox] loss of connectivity after deployment of Security baseline (FINAL) for Windows 10... :)
