Hello. After one of the Windows 10 Professional updates, I lost access to my network drives. I am getting an error: "You do not have access to this release certificate, the security policy of the non-authenticated access organization. This security policy of the organization against dangerous or malicious devices on the network" I have 50 computers in my local network and this problem is on 2 on them. System: Windows 10 Pro 20H2.
Please help.

    Hello,

    For better assistance, can you share us which update you installed recently? Is it KB5001330?

    Regards.

    Hello,
    The problem already occurred a month ago (10-11 March). I uninstalled most of the updates for that day except one (KB4598481)) because it cannot be uninstalled.
    Regards.

    Hi,

    Thanks for your feedback.

    May I know after uninstalling the updates, if the issue still existed?

    Have you tried to delete the mapped drive and re-map it to see if the issue can be resolved?

    What's the status of current mapped drive? If the status is there is a red X on it or it was disappeared directly? Could you please help to provide a screenshot for further troubleshooting?

    Yes, the problem still existed, but as I mentioned, I was unable to uninstall all updates (KB4598481).
    I didn't map a network drive on these computers. These computers used a shortcut of application located on a network drive. When I wanted to access these disks, I would type the address in the command line or in the file explorer. Of course, mapping network drive on these computers was possible before, but not after the updates.
    Regards.

    I have a script that synchronises two drives on different PCs. Just spent a age debugging this previously working script to find that, after a Windows upgrade, the shared status on an updated PC had been removed. Whyyyyy!!!!!!
