    Windows 10 Anniversary update -- SMB shares not available over VPN


    All my laptops have been updated to the Windows 10 Anniversary update. They all connected correctly to the NAS device that uses the SMB connectivity, when connected to the same network. Whenever any are out of the office, they connect to the network over VPN. Then, they can not access the NAS device shares. I have seen this type of problem is wide-spread as Microsoft has changed the way SMB/CIFS file Sharing Support system works.

    How can I fix this?

    How are the shares hosted? Who maintains the network and VPN problems?

    Depending on what type of VPN is used and how it is hosted, can cause those outside of the network to not be able to reach them. Has nothing to do with the other issue which has been fixed by now.

    The VPN is a Dell SonicWALL device and the NAS device is on my network. It all was working BEFORE the Anniversary update was pushed thru. Neither the NetBIOS name or the IP address is working now.

    You are the second one today having issues with whatever update got pushed. I may have to look at my wife's laptop and see which updates that she has not applied, since I have her's set to not update unless I go in and review. I would roll back before this set of updates and lock out any Device Drivers to be updated by Microsoft Update.

    This may still work. It has been a while since I have messed with my wife's laptop to remember which one I did. 2 ways to control Windows 10 automatic updates | PCWorld

    Hello,
    We have the same problem : people in our organisation can access NAS via smb when they are in the local network. But when they join the local ntework via the SonicWall VPN they can't.
    One detail : the smb shares are public, no id nor password is needed to access them.

    Did you find a solution ?
    Do you think this is a good solution ? https://www.tenforums.com/register.ph...7&i=e883829661

    Thanks for your help.

    I have yet to find a fix. My NAS device also allows the mapping of ftp sites. I tried this and the NAS was accessible but not user friendly to use. Therefore it seems that it is definitely a Microsoft setting problem / issue. So far, most of the Registry hacks appear to not work for me.

    I did some searching and found the culprits that are giving everyone Migraines. If Microsoft could break something, they sure are getting really good at doing it. Latest networking issue caused by KB3189866 and KB3185614 - Windows 10 Forums

    To further describe the cause. It is one problematic module:

    I have a work-around. Instead of using the Dell SonicWALL Global VPN Clients software, I configured a Windows L2TP VPN connectoid with the native Windows 10 networking system {VPN Provider: Windows (built-in).} Make sure to change the setting of the VPN from "Automatic" to "L2TP/IPsec with pre-shared key."

    Then make sure to set up the Dell SonicWALL unit to accept L2TP VPN requests.

    Then, there is a Windows 10 Registry manual change. (see:
    https://www.reddit.com/r/techsupport/comments/3sot24/trying_to_conect_windows_10_to_l2tp_vpn/
    (note: Always make sure to create a backup copy of the existing Windows 10 registry of the computer you are working on, before editing.)

    As per the article, Microsoft has determined that IPsec VPN security from a computer in back of a NAT (most routers) device is not secure and disables this.

    At least we are getting somewhere in fixing the mess that Microsoft will not fix at this moment. With Microsoft trying to decide what is safe and what is not, is why we are dealing with these issues with Windows.
