    Any help appreciated.

    I agree with John Bennett. I first started testing out with Ubuntu when 9.04 was out, and this wasn't an issue at all. I was able to browse Windows shares flawlessly, including adding printers via Samba. I'm surprised the Ubuntu team hasn't looked into tightening that configuration for out of the box Windows networking capabilities.

    Also, just wanted to add a piece of information to this very long thread. I just set up set up 3 machines with Linux Mint (an Ubuntu derivative), and this fix works almost flawlessly every time. However, I did notice that experimenting can throw off your configuration, and this may effect all of your Ubuntu machines in the LAN.

    For example, I decided to put wins before lmhosts in the smb.conf file. This knocked out my Samba browsing on every Mint machine that I have running. I simply edited smb.conf back to the way the fix instructs it should be, and restarted the samba service with sudo service smbd restart. After that, I refreshed the network browser on the other machines, and it was working fine.

    To make a long story short, it's definitely possible that one bad config may knock out the whole group of Ubuntu machines. So, always verify you've followed the instructions of the original post to perfection. I've never had it fail on me, except when I do things outside of its suggestions. I've never had to adjust any firewall settings either, just edit smb.conf and nsswitch.conf.

    Hope this sheds light for newcomers!

    Please read this section carefully:

    Windows file sharing is one of the most common attack vectors, so if you poke holes in your firewall for samba browsing, you're essentially removing any positive effect your firewall has.

    Is there a reason you need a firewall?

    Re: Howto: Fix Windows share browsing issues

    Hi, I'm having problems with samba sharing...

    Two days ago everything was fine. I could browse shares on my Windows PC gdea73-pc-1 (netshare and www) just fine and edit files. A long time ago I noticed that from a Windows PC I had to enter my linux user/password to view netshare on THIS LOCAL machine (Ubuntu). I have a user account g73net with no password on this local machine, so I used smbpasswd -a g73net to add it to my share. I also created smbusers in /etc/samba and added this:

    gdea73 = "gdea73"
    g73net = "g73net"

    Now, I always get "failed to mount Windows share" when trying to access *any* windows share on the network besides the Netshare on the local PC. I tried deleting smbusers, and i also typed smbpasswd -x g73net. I even deleted user g73net. Still won't work...

    what do I do?

    wow, different problem
    I can access shares via IP address but I can't via machine name. I didn't change anything in my smb.conf and it was working 2 days ago ...

    Re: Howto: Fix Windows share browsing issues

    Hi all,

    After searching, digging and testing I have no more ideas to try. I explain:

    I'm trying to setup a small local File Server (Ubuntu Server 10.04 and Samba 3.4.7) After looking at the forums about the configurations of Samba and Windows I managed to get all the network running at 99%. The remaining 1% is that the connection to Samba from Windows 7 is performed intermittently.

    XP pcs have no problem accessing, mount drives, read and write to the Samba server. It seemed that Windows 7, after edit various, either. But after a few minutes (sometimes seconds) Windows 7 is no access to the server more, and after a few minutes reconnects.

    The access is done with user authentication and permissions are handled in Ubuntu

    I record somo traffic with Wireshark, but I'm not have enogh level to draw conclusions. If it is necessary I can post too.

    Best Regards!

    Just follow the howto in the first page of this thread and you should be fine.

    Your problem is the opposite of what this thread tries to solve. You'll be better off posting a separate thread. You can also have a look at the 1st link in my sig.

    Re: Howto: Fix Windows share browsing issues

    Hi Dmizer!!,
    great tutorial thanks, but unfortunately didn't work for me.
    Let me explain what I did, first of all, Samba was working perfectly with ubuntu Hardy-Heron version, now I updated to 10.04 and from windows doesn't "see" the linux machine. I can access through \\IPadress\share_folder (this means samba works fine).
    But I can't browse through windows explorer. I've tried all the options that you recommend but no one works.
    From ubuntu I get the error message "Unable to mount location: Failed to retrieve share list from server" Iread that it's a firewall problem, but this doesn't bother to me.
    I attach my smb.conf file.

    Thanks in advance
    P.D. Sorry for my english

    Regards!!
    Kyke

    Re: Howto: Fix Windows share browsing issues

    Hi Dmizer,

    Thanks again for the 'permanent share mount' tutorial - working perfectly.

    Everything else was working perfectly until yesterday afternoon when I booted up win7 to use IE to try and change privacy settings in (of all things) facebook. (Firefox seemed unable to open the privacy tab) IE did give me access, but little joy, but that's all by the by...

    When I returned to Ubuntu (mint 9), I could no longer browse my LAN with nautilus - I get the windows network icon, but clicking on it gives the 'Unable to mount location - Failed to retrieve share list from server' error. I thought (sudo) restart smbd - no effect, restart nmbd - no effect. samba "samba is not installed" - WHAT?

    Re-installed samba (samba4) restart samba gives a bunch of errors and I remembered 4 doing that before, so removed 4 and left 3 in place.

    I've tried all your suggested smb.conf edits with no joy.

    When I try and install winbind it hangs at 'starting winbindd' apparently forever - bombing out leaves stuff locked and requires a reboot and dpkg configure. Same with either cli or synaptic. I have removed it at present, but will attempt a new install...

    Samba is working fine except through nautilus (I can see (and open) shares via firefox, either by ip address or netbios name). I've gone back to win7 and increased the stack as suggested, all to no avail.
