[Solved] Simple File Sharing through Thunar not working as "expected"

Had to start somewhere. Not sure if this is a Samba, Windows 7, or Thunar issue. Maybe someone monitoring this group came across this scenario and has since discovered a resolution. But the network browsing from Linux to Win7 is acting flaky.

Server (linpc): CentOS 6.5 running Samba 3.6.9-69
Client (lanpc): Windows 7 Pro SP1
LAN Workgroup name: LANSYS
--

Samba is configured as a STAND-ALONE server using parameter:
      security=USER
      encrypted passwords = yes

Win7: password protection=off
        128-bit encrytion=off (using 40/56-bit)
        Homegroup services are disabled
        Set LmCompatibilityLevel = 1 (Clients use LM and NTLM authentication, and use NTLMv2 session security if the server supports it)
--

Steps to reproduce the issue:

1. Login to linpc

2. Login to lanpc

3. Open the Thunar Network Browser on linpc

4. Navigate to the lanpc PC name and double click
   - What happens: Popup prompt and I'm forced to enter login/password
   - Expected: I should have gone straight into the share

5. So I enter the proper login/password to access lanpc

6. Now I see the lanpc shared folder [Temp] and double click
   - What happens: Again, I'm forced to enter login/password
   - Expected: I should have gone straight into the share
--

The workaround (to which I don't like), is to remove the password to the user account on the Windows 7 PC (lanpc). Now I'm able to access the lanpc shares from linpc without having to be prompted by Thunar's login/password popup.

Executing this same scenario "to" a Windows XP PC doesn't give me the login/password prompt. It works as expected. And accessing shares "from" Win7 or WinXP "to" Linux works without using login/passwords.

So there is some flaky issue in the way the authentication is occurring into Windows 7. No errors (that I've been able to see), are recorded in any of the /var/log files.

Re: [Solved] Simple File Sharing through Thunar not working as "expected"

It appears my problem has been solved (for me at least). Discovered by researching another TechNet posting Listed below are the changes made. I doubt that all were required but then again the Big Bang solutions always seem to work when dealing with Microsoft operating systems, yes?

The registry

1. KEY: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Lsa
   DATA: everyoneincludesanonymous = 1

2. KEY: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Lsa
   DATA: NoLmHash = 0

3. KEY: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Lsa
   DATA: LmCompatibilityLevel = 1

4. KEY: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\LanManServer\Parameters
   DATA: restrictnullsessaccess = 0

In the Local Security Policy editor under the Security Options folder

1. Microsoft network client: Send unencrypted password to third-party SMB servers = enabled

In the Network Sharing Center

1. Navigate to the Advance Sharing Settings page

2. Select: Enable file sharing for devices that use 40- or 56-bit encryption

Test:

1. Reboot Windows 7

2. Reboot Linux server

3. Open Linux Network Browser application (Thunar)

4. Navigate through the Windows 7 shares without having to enter login/password: Success!
