    Win10 machine visible on network but cannot access shared folder from other devices

    Hi all

    As above, I have a Win10 PC (Win10 Home v1703, build 15063.413) with a shared external drive containing 10TB of media.

    Machine is ethernet wired to Linksys XAC1900 router/modem.

    Many other devices on network include: 4 x iPads, 3 x Win PC's (various versions), WDTV Livehub, etc.

    All access the shared drive, and have been doing so for 2 years.

    The snag? I had to reset the router to factory default, and this of course botched everything on the Win10 machine. At first, it couldn't even be seen on the network by the others (which are all fine and see each other happliy).

    After much trolling of forums over the last two days, I have managed to at least get it visible on the network (at least by the PC's, but still not the tablets or the WDTV). However, none of them can access the Win10 machine. After the "cannot connect" dialogue
    box, ran the networking troubleshooter and got "file and print sharing resource is online Detected but isn't responding to connection attempts".

    Furthermore it also states "the remote computer isn't responding to connections on Port 445...etc".

    Checked via cmd and Port 445 is listening. Even created an incoming rule to ensure it's open.

    Network private

    Discovery enabled

    File and printer sharing on (full permissions for Everyone)

    Password protection off

    Cannot ping other machines but both can ping it

    Pretty much at my wits end. Hoping someone can help me out here...

    Unable to access shares on my Windows 10 Pro desktop.

    Current Win 10 ver is 1703 Build 15063.483

    I discovered this problem today, but as I rarely access shares/resources on my Desktop from other PCs I cannot be sure how long the problem has been there.

    The Desktop is working well in every other way. Using Netstat I can see that port 445 is being listened to,

    TCP 0.0.0.0:445 0.0.0.0:0 LISTENING

    TCP 0.0.0.0:3389 0.0.0.0:0 LISTENING

    but Wireshark shows absolutely no response when I telnet to that port. Even if I try to telnet to port 445 from within the Desktop itself I get no response. However if I telnet to the 445 port using the 127.0.0.1 address then I get a response.

    I have checked that file & printer sharing is configured on the Ethernet port.

    I have tried with the firewall turned off.

    Remote desktop works fine.

    I have searched the 'net extensively and have see 1 of 2 others with the same problem but their solutions have not worked for me. This isn't a tragedy right now, but any help would be appreciated.

    Thanks.
