    Firewall blocking CIFS/SMB access


    Hello,

    I've figured out, that my computer won't let other my devices access shared drives & folders on my computer. I use CIFS/SMB feature from appwiz.cpl -> "Turn Windows features on or off". Then I simply connect to other devices running Windows 10 and either Linux.

    But if I wanted to connect from my laptop to computer -- Both devices Windows 10 1803, Then I got "Error code: 0x80070035 The network path was not found"


    So When I turn off Firewall - Private one - CIFS and SMB work fine.

    Then I tried to add UDP 137,138 and TCP 139, 445 (Which are basically used for SMB and CIFS). Still doesn't work, and I have no clue about that.

    Also, I allowed default File and sharing stuff in Firewall by default option.


    So the problem should be in Firewall (Private networks)


    Any clue?

    Thanks

    :)

    Windows Firewall blocks App Store from downloading new apps

    Hi,

    Let's try to check if the app store you're referring to if it's really blocked by Windows Firewall. See these steps:

    • Open Windows Firewall from the taskbar >
      Firewall & network protection       > Allow an app through firewall.
    • A new window will show up containing the list of the apps that ca be allowed through Firewall.
    • Look for the app you want to be accessed, and make sure that the Domain, Private and Public are ticked. That would allow the app store to be accessed.

    Let us know what happens after doing the suggestion.
