General Information
Microsoft discontinued the official support for NT4 domains many years ago. However, with some modifications, you can still use later published Windows operating systems with a Samba NT4 domain. Anyway consider migrating to a Samba Active Directory (AD) to avoid problems if a future update from Microsoft disables or removes the unsupported NT4 features. For details about migrating, see Migrating a Samba NT4 Domain to Samba AD (Classic Upgrade).
If your operating system is not mentioned on this page, or you are running a Samba Active Directory (AD), the Samba team highly recommends NOT to set any registry modification. |
Joining Windows 7 and Later / Windows Server 2008 and Later to a Samba NT4 Domain
During the join, you see the following error message:
The following error occurred attempting to join the domain "SA": The specified domain either does not exist or could not be contacted.
To enable the client to join the Samba NT4 domain:
- Save the following content to a plain text file named
samba_7_2008_fix.reg
using a text editor such as "Notepad" or "Editor" (not Word/Wordpad/OpenOffice/LibreOffice/etc.):
Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\LanManWorkstation\Parameters] "DomainCompatibilityMode"=dword:00000001 "DNSNameResolutionRequired"=dword:00000000
- Log in using the local
Administrator
account.
- Double-click the file to import it to the Windows registry.
- Reboot to take the changes effect.
Windows 7 / Windows Server 2008 R2: Changing the Primary Domain DNS Name of This computer to "" Failed.
During joining the machine to the NT4 domain you receive the following error:
Changing the Primary Domain DNS name of this computer to "" failed. The name will remain "...". The error was: The specified domain either does not exist or could not be contacted
You can ignore this error message or install a Microsoft hotfix on the Windows machine. For details, see KB2171571.
Windows 8.1 / Windows Server 2012 R2: Error code 0x80090345 launching Windows Credential Manager
After installing the November 2014 update rollup (KB3000850) you see the following error:
Error code 0x80090345 launching Windows Credential Manager
To fix this problem:
- Save the following content to a plain text file named
samba_8_2012_fix.reg
using a text editor such as "Notepad" or "Editor" (not Word/Wordpad/OpenOffice/LibreOffice/etc.):
Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Cryptography\Protect\Providers\df9d8cd0-1501-11d1-8c7a-00c04fc297eb] "ProtectionPolicy"=dword:00000001
- Log in using the local
Administrator
account.
- Double-click the file to import it to the Windows registry.
- Reboot to take the changes effect.
Windows 10: There Are Currently No Logon Servers Available to Service the Logon Request
After you have successfully joined Windows 10 to your Samba NT4 domain, you fail to log on and receive the error:
There are currently no logon servers available to service the logon request.
To fix the problem:
- Set in your primary domain controllers (PDC)
smb.conf
file:
server max protocol = NT1
This setting prevent all your clients to use a newer SMB protocol version than SMB1 when communicating with the PDC. Anyway, the Samba team recommends to use this workaround. Disabling newer SMB versions on the Windows 10 client instead prevent this machine communicating using newer SMB version with all Samba/Windows hosts.
- Restart Samba.
IMPORTANT: Registry Changes That You Should Never Set!
You must not to change the values of the RequireSignOrSeal or RequireStrongKey . Changing the settings breaks the interoperability with Windows and Samba installations. |
If you changed these parameters, reset the values of both keys back to 1
:
- Save the following content to a plain text file named
reset_RequireSignOrSeal_RequireStrongKey.reg
using a text editor such as "Notepad" or "Editor" (not Word/Wordpad/OpenOffice/LibreOffice/etc.):
Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\System\CCS\Services\Netlogon\Parameters] "RequireSignOrSeal"=dword:00000001 "RequireStrongKey"=dword:00000001
- Log in using the local "
Administrator
account.
- Double-click the file to import it to the Windows registry.
- Reboot to take the changes effect.
