    Can't access Windows shares after 1803 update


    I have two Windows 10 Pro computers on the same home network. Prior to the 1803 update I used to keep them in sync by sharing a folder on one, connecting to it on the other, and using sync software. The update has broken this.

    Now I can always ping the other machine by IPv4 address, but most of the time pinging the hostname returns "Ping request could not find host $hostname". Occasionally it does work, and returns an IPv6 address.

    So far, so annoying, but I could simply use the IP all the time in UNC paths instead of the hostname. However, even though I can ping the other machine, I cannot connect to the share. Trying to open \192.168.xxx.xxx through Explorer gets me a lengthy pause and then "Windows cannot access \192.168.xxx.xxx" with Error 0x80070035, "The network path was not found.".

    How can I share files between the computers now?

    Info that may be useful:

    • Neither machine has ever had Homegroups enabled.
    • The only firewall present is Windows Firewall. Avast anti-virus is present, with its firewall feature not installed. Disabling Avast does not help. Turning off Windows Firewall does not help. The Incoming Connections troubleshooter is unable to find the problem.
    • I have different usernames on the two PCs. One is a local username, the other is tied to a Microsoft account. I do not get any box which would allow me to enter a username - it appears to be "can't see the PC" rather than "not authenticated".
    • Enabling the "Function Discovery Resource Publication" service, as suggested by some sites, does not help, except that the machines can now see one another under "Network" in explorer. Seeing the other computer does not help with accessing it.
    • Network discoverability is turned on on both, and they are both set to treat this network as a "private" one.
    • I do not want to re-enable SMB 1. I understand that it was removed for good reasons, and that there should be other ways to share files!


    Thanks for any advice; this is causing me significant workflow problems, as the only way to move files between two PCs sitting right next to each other, right now, is with a USB stick...

    Hello Swaldman, and welcome to Ten Forums.

    You might see if an option in the tutorial below may be able to help. Be sure to double check the items in Option on both PCs.

    Thanks. I'd already been through that before posting, and perhaps should have mentioned the fact. Possibly relevant, though, is that I don't see exactly the same options. For example, I have no "give access to", only "advanced sharing". Under Properties->Sharing, oddly, the "sharing" section at the top is greyed out, and only Advanced Sharing is available. This isn't a new thing - it's been the case on both my PCs for as long as I can remember, so I've just done everything through Advanced Sharing - but perhaps it might indicate to somebody what's different, and hence why things don't work any more...? *hopes*

    Its simpler to use onedrive or google drive on both pcs with same account as it will sync on its own with no imput from you and it will do it very quick once you save or change a file plus you have cload backup

    It sounds like you don't have Use Sharing Wizard checked in Folder Options > View tab like below.

    Hey swaldman,
    You can try setting Prefer IPV4 over IPV6 on both PC's - https://support.microsoft.com/en-us/...advanced-users

    Note: Reboot PC's after applying setting.

    That sounded like a good bet, but the box is checked.

    And this sounded like a hopeful idea as well... but, no dice. Applied to both, rebooted both, waited a bit, same problem.

    Thanks for the attempts! Any other info I can usefully provide?

    My home network has a virtually identical problem, the only exception being that Homegroup had been configured in 1709. Just one of three Win 10 Pro systems, the only 32 bit system, is having problems accessing and being accessed by the other two after the 1803 update. The two others are fine and all three have identical networking and file sharing settings as in Brink's tutorial, settings I have used since before Homegroup was ever thought of. My belief is that the Homgroup disabling in 1803 is the cause - if you go through the registry looking for Homegroup entries they are still there, hundreds of them, and in the 32 bit system's firewall Homegroup is still present and checked though it isn't possible to remove or uncheck it. Pro tem I'm using Teamviewer as a workaround and I'm not wasting any more hours trying to sort it. It's a bug.

    After quite a lot of wasted hours I found... maybe a solution, maybe more of a workaround, elseweb: turning off and on the association of File & Print Sharing with the network adapter on the target computer (the one whose share you're trying to connect to) appears to fix it. So far the fix has stuck for me, but others have reported it only lasting until the next reboot, or possibly (if on wifi) the next network change.

    Cycling this can be put in a Powershell script:

    Code:
    Disable-NetAdapterBinding -name "adaptername" -ComponentID ms_server
    Enable-NetAdapterBinding -name "adaptername" -ComponentID ms_server
    Needs to be run as Administrator.
