Wow!
Thanks @markf , nice first post and Welcome!
I just got this problem last week and just narrowed the problem to Windows but did not solve it since I didn't have the time then.

On the subject, I would like to solve without SMB1 though... had jobs related to Ransomware... they are THE worst.

Cheers!

Hi Guys, I am experimenting with Linux for the first time so please excuse any stupid remarks.

I have been having the exact same problem and I think I have a fix... of sorts.

The problem lies with changes that Microsoft have made to the latest update to Windows 10. In windows, type "winver" in the run box. The latest version is 1803.

Among other changes, SMB1.0/CIFS file sharing support has been disabled by default. If you go to Control Panel\All Control Panel Items\Programs and Features\Turn Windows features on or off, scroll down to the relevant box. There are 3 options:

SMB Automatic Removal
SMB Client
SMB Server

I ticked the bottom two, saved, rebooted and problem solved. I can now see all the shares on my Win10 box from mt Linux Lite box.

Microsoft recommend that you completely remove SMB1.0/CIFS from Windows 10 to prevent the spread of ransomeware. It would have been nice if that had been more widely disseminated.

Another Gotcha! is that the whole concept of the Homegroup (as opposed to a Workgroup) has been abandoned. There is no support for Homegroups in ver 1803. Not only that but when you upgrade to 1803 (which is automatic), your homegroups will have gone.

Where did you get that Samba file from? That's not what we provide. Our version is simpler and works fine with Win10.

I can't see the shares and can't see the server either by name or by IP address. Error is "Windows cannot access <SERVERNAME> Error code 0x80004005 Unspecified error" or "Windows cannot access <IPADDRESS> Error code 0x80070035 The network path was not found."

OS is LinuxLite v3.8 with updates applied. The user accounts and passwords on the Ubuntu (LinuxLite) machine and Windows machine are identical. A Samba user account identical to the Linux user account has been created.

The Linux permissions on data, data2, and DATA3 are: Owner - <me (me)> Access - Read & Write Group - <me> Access - Read & Write Others - Read & Write

Or maybe you prefer it this way:
ls -dl /media/marc/data/
drwxrwxrwx 4 marc marc 4096 Apr 21 00:34 /media/marc/data/

ls -dl /media/marc/data2/
drwxrwxrwx 9 marc marc 4096 Mar 28 06:11 /media/marc/data2/

ls -dl /media/marc/DATA3/
drwxrwxrwx 8 marc marc 4096 Apr 19 10:09 /media/marc/DATA3/


samba.conf is:

#
# Sample configuration file for the Samba suite for Debian GNU/Linux.
#
#
# This is the main Samba configuration file. You should read the
# smb.conf(5) manual page in order to understand the options listed
# here. Samba has a huge number of configurable options most of which
# are not shown in this example
#
# Some options that are often worth tuning have been included as
# commented-out examples in this file.
#  - When such options are commented with ";", the proposed setting
#    differs from the default Samba behaviour
#  - When commented with "#", the proposed setting is the default
#    behaviour of Samba but the option is considered important
#    enough to be mentioned here
#
# NOTE: Whenever you modify this file you should run the command
# "testparm" to check that you have not made any basic syntactic
# errors.

#======================= Global Settings =======================

[global]
    unix password sync = yes
    log file = /var/log/samba/log.%m
    passdb backend = tdbsam
    writeable = yes
    netbios name = POWEREDGE1800
    server role = standalone server
    os level = 20
    max log size = 1000
    syslog = 0
    server string = %h server (Samba, Ubuntu)
    dns proxy = no
    encrypt passwords = yes
    panic action = /usr/share/samba/panic-action %d
    map to guest = bad user
    pam password change = yes
    passwd program = /usr/bin/passwd %u
    workgroup = WORKGROUP
    usershare allow guests = yes
    obey pam restrictions = yes
    passwd chat = *Enter\snew\s*\spassword:* %n\n *Retype\snew\s*\spassword:* %n\n *password\supdated\ssuccessfully* .

## Browsing/Identification ###

# Change this to the workgroup/NT-domain name your Samba server will part of

# server string is the equivalent of the NT Description field

# Windows Internet Name Serving Support Section:
# WINS Support - Tells the NMBD component of Samba to enable its WINS Server
#   wins support = no

# WINS Server - Tells the NMBD components of Samba to be a WINS Client
# Note: Samba can be either a WINS Server, or a WINS Client, but NOT both
;   wins server = w.x.y.z

# This will prevent nmbd to search for NetBIOS names through DNS.

#### Networking ####

# The specific set of interfaces / networks to bind to
# This can be either the interface name or an IP address/netmask;
# interface names are normally preferred
;   interfaces = 127.0.0.0/8 eth0

# Only bind to the named interfaces and/or networks; you must use the
# 'interfaces' option above to use this.
# It is recommended that you enable this feature if your Samba machine is
# not protected by a firewall or is a firewall itself.  However, this
# option cannot handle dynamic or non-broadcast interfaces correctly.
;   bind interfaces only = yes



#### Debugging/Accounting ####

# This tells Samba to use a separate log file for each machine
# that connects

# Cap the size of the individual log files (in KiB).

# If you want Samba to only log through syslog then set the following
# parameter to 'yes'.
#   syslog only = no

# We want Samba to log a minimum amount of information to syslog. Everything
# should go to /var/log/samba/log.{smbd,nmbd} instead. If you want to log
# through syslog you should set the following parameter to something higher.

# Do something sensible when Samba crashes: mail the admin a backtrace


####### Authentication #######

# Server role. Defines in which mode Samba will operate. Possible
# values are "standalone server", "member server", "classic primary
# domain controller", "classic backup domain controller", "active
# directory domain controller".
#
# Most people will want "standalone sever" or "member server".
# Running as "active directory domain controller" will require first
# running "samba-tool domain provision" to wipe databases and create a
# new domain.

# If you are using encrypted passwords, Samba will need to know what
# password database type you are using. 


# This boolean parameter controls whether Samba attempts to sync the Unix
# password with the SMB password when the encrypted SMB password in the
# passdb is changed.

# For Unix password sync to work on a Debian GNU/Linux system, the following
# parameters must be set (thanks to Ian Kahan <<[email protected]> for
# sending the correct chat script for the passwd program in Debian Sarge).

# This boolean controls whether PAM will be used for password changes
# when requested by an SMB client instead of the program listed in
# 'passwd program'. The default is 'no'.

# This option controls how unsuccessful authentication attempts are mapped
# to anonymous connections

########## Domains ###########

#
# The following settings only takes effect if 'server role = primary
# classic domain controller', 'server role = backup domain controller'
# or 'domain logons' is set
#

# It specifies the location of the user's
# profile directory from the client point of view) The following
# required a [profiles] share to be setup on the samba server (see
# below)
;   logon path = \\%N\profiles\%U
# Another common choice is storing the profile in the user's home directory
# (this is Samba's default)
#   logon path = \\%N\%U\profile

# The following setting only takes effect if 'domain logons' is set
# It specifies the location of a user's home directory (from the client
# point of view)
;   logon drive = H:
#   logon home = \\%N\%U

# The following setting only takes effect if 'domain logons' is set
# It specifies the script to run during logon. The script must be stored
# in the [netlogon] share
# NOTE: Must be store in 'DOS' file format convention
;   logon script = logon.cmd

# This allows Unix users to be created on the domain controller via the SAMR
# RPC pipe.  The example command creates a user account with a disabled Unix
# password; please adapt to your needs
; add user script = /usr/sbin/adduser --quiet --disabled-password --gecos "" %u

# This allows machine accounts to be created on the domain controller via the
# SAMR RPC pipe. 
# The following assumes a "machines" group exists on the system
; add machine script  = /usr/sbin/useradd -g machines -c "%u machine account" -d /var/lib/samba -s /bin/false %u

# This allows Unix groups to be created on the domain controller via the SAMR
# RPC pipe. 
; add group script = /usr/sbin/addgroup --force-badname %g

############ Misc ############

# Using the following line enables you to customise your configuration
# on a per machine basis. The %m gets replaced with the netbios name
# of the machine that is connecting

# for something else.)

# Allow users who've been granted usershare privileges to create
# public shares, not just authenticated ones
