Second Domain Controller (Windows 2008) alongside Samba 4 AD

Hello, everyone,
I have this problem:
1 NS7 migrated from NS6 in turn inserted into a previous linux system as consolidation of several very old servers.
Some machines of the production structure (win98, OS/2, WinXP, RH5) are giving me problems and the supplier suggests me to try with a Windows 2008 AD.
I wanted to insert a second Domain Controlle Windows 2008 alongside Samba 4 AD.
But when I insert it it gives me problems of access to the existing AD structure.
Has anyone tried this configuration and got any suggestions?
Thank you
Mario Zanon

That’s not supported in Nethserver. You may add a Windows Server as domain member but not as domain controller.

If you want to try it:

For RH5:

For XP it should be possible with some registry hacks.

Thanks, Markus, for your answer.
I know that Nethserver does not support more than one domain controller, although I consider it a serious limitation, in SMEs already from 5 servers and 25 clients I always insert a second domain controller to ensure continuity of service.
Today, with virtualization, even small companies tend to have a server for each service (mail, administrative management, production management, etc.). Limiting the structure to a single server means drastically reducing the potential customer base.
Having said that, I need to insert a Microsoft domain controller to see if I can solve the problems created with the insertion of the Nethserver and especially with the passage from Nethserver 6 with Samba 3 to Nethserver 7 with Samba 4 (done directly from the Nethesis).
I have now discovered that probably the problems were created by the fact that the Samba 4 Machine running in a Linux container, was configured for a minimum level of the domain at 2008R2, so not tested with machines using previous security protocols, if so the problem seems unresolvable and I will have to proceed in another way.

You are right that multiple DCs would be nice, here’s another topic about that.

You may use Nethserver in a way to split the services on different servers, that’s already possible but not with DC.

Do you know hotsync? It provides a slave backup that could be made active manually if the master server goes down:


Hi there!

AFAIK it is NOT possible to connect Win98 and OS/2 to anything above Win2003 Server.
This is due to old NTLM requirements, which are (rightfully) discarded nowadays.

I still have OS/2 and ECS around, also a Win98SE. I can’t even connect Win98 to my several NAS, as all use Samba under the hood.

My solution was to use a Win2K server for migration, and left it running as a “gateway” service.
The available Windows 2003 Server didn’t work for me!

Your mileage may vary…
