    Bonkers network problem with build 330


    Hi folks

    This thing is driving me crazy (even more than I am normally !!) -- Update so build 330. This machine can communicate with others on LAN both Windows and Linix (NAS servers) on OUTBOUND. On INBOUND this machine can only accept connections from other WINDOWS machines --all NAS INBOUND connections are refused

    There must be some setting (there are always about 10 zillion in Windows) that I've got wrong -- haven't changed any AFAIK. The non 330 build Windows machines are all working.

    Here's what typical NAS shows me -- simply want to send a file over to Windows --not normally a problem -- I send over a batch file that is run on the Windows machine to connect to the NAS server and run a data backup (of the Windows User data).

    Ping also unreachable --which is rare as that generally always works !!! (and I've done the obvious --the Windows LAN address is definitely correct)

    From the Windows machine (OUTBOUND) no problems

    Any ideas -- or is Microsoft deciding to get tough with Non Windows inbound connections to windows machines !!!!

    Back to basics......
    Choose 1 machine
    Turn sambas on
    Check both computers have ip addresses
    Check or disable firewalls turn off AVs and any other malware detectors
    check again and try pinging from computer 1
    clear and renew ipconfig

    make sure net discovery is on both

    Hi there

    Thanks but "been there Done that Bought the T-shirt etc" !!!!

    I think I've discovered it though -- really weird problem

    The remote Windows machine is on a dual boot single SSD -- Linux installed first and then Windows so at boot there's an option (probably via GRUB2) to choose the OS.

    I don't like dual booting at all normally but I thought I would test.
    Restoring Windows (same version) to a full non dual boot HDD -- it seems to be working.

    Not sure though why GRUB should hose up INBOUND processes though - surely after boot the OS works as it should "normally".

    Anyway that's the end of me even thinking about Dual booting from an internal SSD / HDD any more !!

    Cheers

    Not sure though why GRUB2 should hose up INBOUND processes though - surely after boot the OS works as it should "normally". I.e the Windows boot loader would be started and Windows boots normally.

    Anyway that's the end of me even thinking about Dual booting from an internal SSD / HDD any more !!

    I always manage to break things via really weird problems though - I'm sure I'm not the only person whose dual booted Linux and Windows in the past without hosing up Windows networking.

    I won't mark the problem as solved as it clearly isn't -- however if anybody can suggest a reason or suggest a fix I'm willing to try it -- restoring the SSD only takes me around 7 mins so testing not a problem.

    Been a while since I rebuilt a Grub, but I don't have a really new one to test
    if there is an networking part to it.

    Hi there
    could be an idea - trouble with that is it will then need Windows to be re-installed -- if I just restore the windows image I'll get the same problem since the BCD will be just the same.

    Still if I've got nothing to do later !!

    Hi there

    Grub shouldn't have any networking stuff in it at all --all those components will be loaded and started by the relevant OS'es.

    could be an idea - trouble with that is it will then need Windows to be re-installed -- if I just restore the windows image I'll get the same problem since the BCD will be just the same.

    Hi there
    I restored my old SSD with the two systems on it and then installed the 20H2 version from UUP DUMP-- Guess what -- everything working 100%.

    So I'll mark as solved -- obviously something in that build in Windows wasn't working properly ""

    anyway thanks for suggestions --believe it or not on this Forum people do take notice of what people suggest and are grateful when they take the time to post -- so thanks anyway !!

    Cheers
