    Have you tried to reboot your router? This often solves connection problems. Have you checked that the router firmware is up to date? This another thing that can get things working.

    Yeah, that's because the Master Browser of the network seems to work properly with this bug. The first machine you turn on becomes the Master Browser if all the other machines are off.

    Kubuntu 16.04

    Freshly installed Windows 10 Home 64bit on two different machines cannot connect reliably to my SMB shares. Various Androids and a Windows 7 PC can connect without issue.

    I've already asked on but didn't get any answer. Please don't mind that I post the issue here again:

    At random the network drive connects, at 1 of 50 trials. I can browse my files for 10 seconds or so. Then it drops dead again..

    Workgroup is correct. Sambauser has a username and password set on the server.

    I tried:

    • Adding "AllowInsecureGuestAuth" key to \HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanWorkstation\Parameters
    • Adding "server max protocol=SMB3" to smb.conf on the server
    • Connecting with the ip like this "\\\share"
    • Disabling Network Adapter Power Saving
    • Start Windows 10 in Diagnostic Mode
    • Disable SMB2/3 in Windows, enable SMB1
    • Adjust smb.conf further according to content in this thread
    • Add the share as a "link" in File Explorer as a user previously described. Result is the same, this works at random for 10 seconds, then it's dead again

    I carefully read through this topic but it didn't help.

    If you know anything, please share.

    What version of Windows 10 are you running. I have no issues with 1607 (anniversary) but even with a clean install of Creators Edition with NO other software installed the master browser is an issue. If I boot a 1607 computer first and it is the master browser, then I can see my CU edition but not if I boot the CU first. CU is plenty of nothing all happening all at once.

    Windows 10

    It may be because other devices are using port 139 and Windows 10 is now using port 445.

    I have a public (no user/pass) Samba Share running on Remote Debian Stable Server which I have been accessing fine with Windows 10 for ages with the UNC path:

    \\\share (and file shortcuts etc)

    But recently (around Windows Creator update i think) that path is timing out giving same error as forum user: irgendwer.

    Event Viewer logs this after the timeout (20-30s):

    Event Viewer->Application & Service Logs->Microsoft->Windows->SMBClient->Connectivity
    Failed to establish a network connection.
    Error: Device Timeout
    The specified I/O operation on %hs was not completed before the time-out period expired.
    Server name:
    Server address: (i changed the ip for privacy)
    Instance name: \Device\LanmanRedirector
    Connection type: Wsk
    This indicates a problem with the underlying network or transport, such as with TCP/IP, and not with SMB. A firewall that blocks TCP port 445, or TCP port 5445 when using an iWARP RDMA adapter, can also cause this issue.
    Turns out Windows 10 SMBClient tries to connect to remote SMB server on TCP port 445, and now (not sure if before they were or not) my ISP is blocking outgoing TCP port 445!! - Possibly because of cyber security threats like WannaCry.

    My Samba server listens on 139 and 445 by default, and I can connect to it's 139 using telnet, but I cannot make Windows SMBClient use port 139, people say you cannot. Even trying specify port in UNC path etc (apparently \\\share converts it to WebDAV).

    So I am not sure WHAT changed (Windows or my ISP or both etc) but basically I think I am screwed Samba wise as Windows is locked to 445 and ISP is blocking it lol, I even tried a TCP port relay on my localhost:445-> but of course Windows System process is listening on 445 so I cannot bind, attempts to disable 'server' and netbt left the port listening etc and I'm not wasting any more time on it.

    I'll probably switch to WebDAV/NFS or SFTP Net Drive (pretty cool BTW, better than swish) or something, but I'm subscribing here in case any of you figure it out, good luck, especially to irgendwer, he seems to have tried everything!
