Windows update not working with windows firewall RRS feed

  • Question

  • I have a Surface Pro with Windows 8.1, the firewall is configured to block both inbound and outbound connections. I have rules set up to allow company traffic through the tablet as well as the following rules for Windows update.

    Process - %SystemRoot%\System32\svchost.exe
    Services - Windows Update
    Remote ports 80, 443

    Process - %SystemRoot%\System32\svchost.exe
    Service - BITS
    Remote Ports 80, 443

    Process - %SystemRoot%\System32\wuauclt.exe
    Services - Windows Update

    I am still unable to get updates with the tablet without disabling the firewall. I am getting the Window Update Error Code 80240438. Please let me know if any of you have any experience with this issue. 

    Thanks,

  • Hi,

    It's not enough to allow Windows update related service. Also need contains Windows update server.

    The error code you mendtioned means network problem. For your situation, it's your firwall problem.

  • Can you be a bit more specific? Which process is the Windows update server? Which services or applications need outbound access in order for Windows Update to function properly?

  • I used to have this problem.

    In order to fix it I had to stop the wuauserv service and then start it.

    in the command prompt run:

    net stop wuauserv

    net start wuauserv

    it seemed weird to me because rebooting didn't fix it.

    I only have one outbound rule for windows update which is the same as your first one:

    Program:  %SystemRoot%\System32\svchost.exe
    apply to this service:  Windows Update   -- wuauserv
    Remote ports tcp 80, 443

    hope this helps,

    shawn
