Connecting from Windows 7 desktop to Red Hat Samba shares

Windows 7, connecting to Samba shares - Super User

How can I connect to a Samba share with authentication using Windows 7?

We have a bunch of Linux, HP-UX and AIX servers on our network with folders shared using Samba. These are not connected to our Active Directory or anything, we just type a user name and password when we connect to them. They still all work fine from Windows XP, but we've upgraded a couple of machines to Windows 7 and they can't access the shares. You get prompted for a password but it says "The specified network password is incorrect" (it's not).

1. Run: gpedit.msc
2. Find:

   Console Root -> Local Computer Policy -> Computer Configuration -> Windows Settings -> -> Security Settings -> Local Policies ->Security Options

   When you're there change the following policies

3. Microsoft network client: Send unencrypted password to third-party SMB server: Switch it to "Enabled".
4. Network security: LAN Manager authentication level: Select the option: Send LM & NTLM - use NTLMv2 session security if negotiated.

Thanks, this solves the problem. It sounds like we should probably be upgrading samba on all our servers too, but that will take a while... –  Colin Pickard Mar 3 '10 at 9:56 doesn't work for me >:( –  endolith Jun 10 '11 at 4:22

@ Cy. Instead of running gpedit.msc and doing all that navigation, secpol.msc takes you directly to your security settings.

Everything else is correct otherwise.. –  user140593 Jun 16 '12 at 20:17

@user168261: I'm running latest version of Samba. #4 works (and is needed). #3 is unnecessary (with later Samba versions). –  Gerrat Jul 11 '13 at 21:05

I am running Windows 8 and this solution did not work for me. –  ktamlyn Jul 25 '13 at 20:35 

Get Vista and Samba to work | TechRepublic

1. Open the Run command and type "secpol.msc".
2. Press "continue" when prompted by Vista.
3. Click on "Local Policies" --> "Security Options"
4. Navigate to the policy "Network Security: LAN Manager authentication level" and open it.
5. By default Windows Vista sets the policy to "NTVLM2 responses only". Change this to "LM and NTLM – use NTLMV2 session security if negotiated".

+100 if I could! Been trying to get this working for over a day. –  Gerrat Jul 11 '13 at 21:05

add a comment |  up vote3down vote If you're running an old version of Samba, it's possible that you're run into this problem. Here is some further discussion. Basically, Windows Vista and 7 disable an old and insecure method of authentication which Samba was using by default. Tweaking the registry setting as described in the article should get it working. Ideally, of course, you would upgrade Samba to a new version, but that might not be possible at the moment.

If this doesn't work, could you post the version of Samba that you're running?

2,14721029 I did not have a LmCompatibilityLevel key on my Win7 machine. I don't know if creating the key would have worked? The gpedit solution worked for me anyway. –  Colin Pickard Mar 3 '10 at 10:02 What version of Samba is required? Is it a samba configuration issue? –  endolith Jun 10 '11 at 4:00 add a comment |  up vote0down vote I had same issue. When I try to connect I get 0x80004005 permission error:

While I do:

• Change Network security: LAN Manager Authentication Level to “Send LM & NTLM responses”
• Change Minimum Session Security for NTLM SSP to disable “Require 128-bit encryption” into “No Minimum Security”.
• Uninistalling KB2536276.

another thing stop from done is:

• activate Client for Microsoft Networks in my WiFi dangle Network panel.

Enabling File and printer sharing for Microsoft Networks in Network panel allow me access to Win7 shared folders.

Windows 7 not able to connect to Samba
 

I'm trying out Win7, and i'm trying to connect to the networked samba share as I have been able to in Vista & XP with no issues. Samba is running on Ubuntu, if that helps.

I've tried changing the following in the local security policy as i've seen on as the answer on some sites, and it's still not working:


Local Policies - Security Options

Network security: LAN Manager authentication level Send LM & NTLM responses

Minimum session security for NTLM SSP

Disable Require 128-bit encryption

I am getting this in my samba error log:
[2009/09/06 15:15:53, 0] lib/util_sock.c:read_data(534)
read_data: read failure for 4 bytes to client 192.168.1.101. Error = Connection reset by peer


Has anyone seen this issue yet?

Are you running Samba 3? If you are try adding this to the smb.conf
client ntlmv2 auth = yes

XXX

In case you've tripped across this like I have, and the good answer from @Josh Budde hasn't helped, you might find that your Samba setup is using ADS as its authentication source (you'll find the line "security = ADS" in your smb.conf).

In my case I was trying to access a Samba source on a remote, non-trusted Domain, and when entering login details I entered the username in the Windows NT format e.g. DOMAIN\first.last.

Even though the credentials were correct, the Samba server would reject the credentials and the Samba error log had the message as per the Op.

The fix is really easy - enter your username in the LDAP/ADS format of [email protected] (e.g. [email protected]).
