Cannot Map a drive on Windows 7 to an Ubuntu share except on one PC

Hello,

I am new to Ubuntu to 10.10 and hit a snag.

I just set up an Ubuntu server (10.10), installed Gnome, Samba, Nautilus, ACL and Eiciel and then created a share.  I gave the user I created (user1) full rights to that share.  I went to my Windows 7 Professional 32-bit box and could see the Ubuntu server and the share and could map a drive to it using "User 1" credentials.  All seemed completely successful until I disconnected and went to a different PC running Windows 7 Ultimate 64-bit and attemted to map to the ubuntu share.  I could see the server and share from that PC, but when I attempted to map a drive it rejected the "User1" credentials.  I have since tried on other Windows 7 boxes and could not successfully map to the Ubuntu Share.   I can still connect and disconnect from the first Windows 7 PC but from no others.   What am I missing ?

Thanks

It might be a firewall issue. Have you tried to disable the firewall in your windows 7 boxes on which you are facing issue.

Yes, I have tried turning off the firewall.

Have you tried to allow the guest ok in your smb.conf to allow guest user to mount the share so that you can check whether its a user issue or something else.

Could you please show me your smb.conf file here.

# 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.
# A well-established practice is to name the original file
# "smb.conf.master" and create the "real" config file with
# testparm -s smb.conf.master >smb.conf
# This minimizes the size of the really used smb.conf file
# which, according to the Samba Team, impacts performance
# However, use this with caution if your smb.conf file contains nested
# "include" statements. See Debian bug #483187 for a case
# where using a master file is not a good idea.
#

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

[global]

## Browsing/Identification ###

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

# server string is the equivalent of the NT Description field
      server string = %h server (Samba, Ubuntu)

# 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.
      dns proxy = no

# What naming service and in what order should we use to resolve host names
# to IP addresses
;   name resolve order = lmhosts host wins bcast

#### 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
      log file = /var/log/samba/log.%m

# Cap the size of the individual log files (in KiB).
      max log size = 1000

# 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.
      syslog = 0

# Do something sensible when Samba crashes: mail the admin a backtrace
      panic action = /usr/share/samba/panic-action %d


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

# "security = user" is always a good idea. This will require a Unix account
# in this server for every user accessing the server. See
# /usr/share/doc/samba-doc/htmldocs/Samba3-HOWTO/ServerType.html
# in the samba-doc package for details.
#   security = user

# You may wish to use password encryption.  See the section on
# 'encrypt passwords' in the smb.conf(5) manpage before enabling.
;      encrypt passwords = yes

# If you are using encrypted passwords, Samba will need to know what
# password database type you are using.  
;      passdb backend = tdbsam

      obey pam restrictions = yes

# 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.
      unix password sync = yes

# For Unix password sync to work on a Debian GNU/Linux system, the following
# parameters must be set (thanks to Ian Kahan <<kahan@informatik.tu-muenchen.de> for
# sending the correct chat script for the passwd program in Debian Sarge).
      passwd program = /usr/bin/passwd %u
      passwd chat = *Enter\snew\s*\spassword:* %n\n *Retype\snew\s*\spassword:* %n\n *password\supdated\ssuccessfully* .

# 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'.
      pam password change = yes

# This option controls how unsuccessful authentication attempts are mapped
# to anonymous connections
      map to guest = bad user

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

# must have this setting enabled. If you are the BDC you must
# change the 'domain master' setting to no

# Another common choice is storing the profile in the user's home directory

# 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)

# NOTE: Must be store in 'DOS' file format convention

# 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

# SAMR RPC pipe.

; 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

########## Printing ##########

# If you want to automatically load your printer list rather
# than setting them up individually then you'll need this
#   load printers = yes

Here you have mentioned that ou were using user1 to mount the share on windows but in your smb.conf there are no any user named user1. There are just four users only.

valid users = john, mike, mikej, root

On Both the Windows machines are you using the same user credentials to mount your samba share ? Please confirm.

Please show us output of below given command.

# ls -la /home/mike/Documents
