    Network Discovery will not stay on


    I have a strange problem and can't find a fix.

    I've lost the ability to connect to a Win 7 computer on my network. It has worked for a very long time but stopped working after I replaced my SSD on the Win 10 desktop computer. I cloned a new Samsung 860 1TB SSD drive from the old Samsung 850 512GB SSD drive using the Samsung Data Migration software. (This worked with one other exception. I have to reauthorize MS Office)

    I also have a Win 10 laptop on the network and am able to connect to it.

    In the Network and Sharing Center, Network Discovery will not stick in the On setting for Private and Guest or Public areas. It is On and stays On in the All Networks area.

    File and Printer sharing is on.

    I have looked at the threads in this forum as well as the following threads:
    Network Discovery will not stay on - Microsoft Community
    https://support.microsoft.com/en-ca/...ring-center-in
    All of the services mentioned are turned on correctly .

    I pinged the Win 7 computer and get a correct ping.

    I can see the Win 7 computer in File Explorer but can't access it. (I get the window "Windows cannot access\\Win7). The detail is Error code 0x80070035.

    I ran the Windows network trouble shooter and it was unable to find the problem.

    I turned off both Windows Defender and Defender Firewall and this didn't fix the issue either.

    This seems very odd because I can access the Win 10 laptop but not the Win 7 desktop. The only thing that has changed since it worked correctly was the change and cloning of the Win 10 desktop SSD.

    Any suggestions?

    Solved


    After beating my head against the wall for many hours, I found the solution quite by accident.

    It was yet another Microsoft screw up. Here is an article describing the issue:
    Microsoft's killer Windows 7 patch: Breaks networking, flags legit PCs as 'Not genuine' | ZDNet

    The article reports that the 3 updates caused various problems including blocking network access.

    I uninstalled the update KB4480970 and I have regained network access to the Win 7 computer.

    I'm not sure what's worse - security problems or MS screw ups.

    Thanks to anyone who read this thread and considered replying.

    Quality Control does it exist?
