Can't connect to local network share

[monsterjamp]

I used to be able to connect to my computers through the local network but for some reason I can't anymore.
In nautilus I can still see my other computer being listed but when I double click on it, it returns an error message saying:
"Unable to access location Failed to retrieve share list from server: Connection timed out"

I should mention the computer with Ubuntu (T400) is connected to the network via WiFi and my other computer (Windows 7 named User-PC) is connected to the network via ethernet and it has no password on it. I'm trying to access User-PC with my T400.

I've tried Googling for a solution but nothing seems to work.

Post the command line output of this command
smbtree -d3...there should be a lot of output. Cut and past it in between the
code blocks. The easiest way to post the data is to click on the # icon at the top of the advanced editor and paste.

192.168.1.69 is the computer I'm trying to connect to so it seems that the computer is being detected but I can't access it's share.

Yes but there should be more lines in the output that list why you do not see the shares displayed. Connecting is only part of the process. Here is some of what I get after connecting on my network

I have no idea why shares stopped working, maybe something is messed up with the network settings? Is there a way I can completely reinstall the network manager to make sure everything is installed properly?

Why not send me the rest of the output of smbtree -d3?

Network Manager has nothing to do with this problem.

That is all of it :(

Although the first time I didn't use sudo.

You do not need to use sudo. Let's add more debug and see what we get. Post the text output of this (not a screen capture)

The only difference I see between my output (to that point) is with this

SO_RCVBUF = 372480
These are the buffer sizes.

Post the output of the Samba configuration file
cat /etc/samba/smb.conf

What version of Samba are you running?
samba -V

[monsterjamp]

abraham@abraham-T400:~$ cat /etc/samba/smb.conf
#
# 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]

## 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

# 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

#### 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

####### 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.
server role = standalone server

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

# 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'.

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

I see no shares configured with smb.conf. I assume you have made usershares with the GUI interface. I would try unsharing the shares you have made and create new ones.

[monsterjamp]

I've never used the GUI interface of Samba (until your post) so I'm not exactly sure what to do. Also just to clarify, I'm trying to access shares from another computer (Windows 7) there is nothing I want to share from this computer (Ubuntu).

Ahhhh, so your Ubuntu machine is a SMB client to the Windows machine file server (service). The problem is with the Windows machine not advertising the shares. My first check would be to see if the Windows machine has NETBIOS over TCP (NBT) operating and share discovery is working.

[monsterjamp]

It works now! I was under the impression that it was a problem with the computer running Ubuntu because I haven’t touched my Windows 7 computer in a month (and other computers running Windows was still able to connect to it). Thanks for your help.

[bab1]

Great. Glad I could help.

Window to Windows share browsing is slightly different than Windows to Samba.
