Joining Windows 7 or Windows 8 Computers to Samba3x Domain
Posted by , Last modified by rbTech Staff on 09 May 2013 09:22 AM

There are a couple of requirements that need to be met before attempting to join a Windows 7 machine to a Samba-based domain.  First, the Samba package on the server must be updated to samba3x (this is now in the CentOS repository).  The other requirement is registry and local security policy changes on the Windows 7 client. 

The registry changes are as follows (and are also available as a .reg file attached to this article):

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\LanmanWorkstation\Parameters]
"DomainCompatibilityMode"=dword:00000001
"DNSNameResolutionRequired"=dword:00000000

The local security policy changes are as follows: Go to Local Group Policy Editor by using the gpedit.msc command within Windows 7 search. You get there by clicking the Windows Start bubble.

Under Computer Configuration > Windows Settings > Security Settings > Local Policies > Security Options,

"Network Security: LAN Manager authentication level" should be "Send LM & NTLM responses"
"Network Security: Minimum session security for NTLM SSP based (including secure RPC) clients" uncheck "Require 128-bit encryption"
"Network Security: Minimum session security for NTLM SSP based (including secure RPC) servers" uncheck "Require 128-bit encryption"

The machine should be rebooted before joining it to the domain.
