Domain in NT 4.0 and subdomain in W2K

I have a LAN with Win2000 SBS and domain TAXBACK.something.ie and another LAN with Windows NT 4.0 and domain DOMAIN connected through 2 firewalls with VPN. How can I connect  the two domains so that DOMAIN to be the root (something.ie) and TAXBACK to be subdomain of DOMAIN (organize them in a tree)? I cannot connect  to TAXBACK from Win2K Server or Win2KPro: Cannot connect to pre-Windows 2000 domain DOMAIN or Cannot connect to pre-Windows 2000 domain controller domain_controller_name

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years.

Well if they were both NT, you would set up a Trust.
I would look up trust relations in both Help on both servers and see if you can set it up.
That's the only way I know of to authenticate in seperate Domains.

I hope this helps !

The domain structures of NT4 and W2k active directory are different, so you cannot create a subdomain tree like desired with an NT 4 box.

You can, however, establish trust relationships between the NT4 domain and the W2k domain to gain access to the other domain's ressources.

For this to work you will have to supply proper NT 4 compatible NETBIOS name resolution (WINS Server, DNS won't do). Then create the trust relationships.

When I tried to establish trust relationships the result was following:

C:\>netdom trust taxback /Domain:domain /add
This operation is not supported on a Microsoft Small Business Server

The command failed to complete successfully.

C:\>netdom trust domain /Domain:taxback /add
This operation is not supported on a Microsoft Small Business Server

The command failed to complete successfully.

C:\>netdom trust domain /Domain:taxback /add /twoway
This operation is not supported on a Microsoft Small Business Server

The command failed to complete successfully.

C:\>netdom trust domain /Domain:taxback /twoway
The parameter is incorrect.

Try "NETDOM HELP" for more information.

Correct - SBS does NOT support trusts - it is designed for SMALL businesses with a single DOMAIN.

You need to instal a full NT or win2k server for this. I would double check the other limitations on SBS.

I hope this helps !

Is it possible to connect domains if NT4 is upgraded to Win2K (SBS or full 2K server) as it must be the perent domain?

SysExpertCommented:
I do not know if SBS is upgradable. Check the MS web site.

You need an entire new server, or backup the SBS server, and wipe it clean and install standard NT4, and restore your data.

You will need to re-install all the applications that were used.

I hope this helps !

SBS does not support other domain controllers in its domain. I tryed to install Win2K server over SBS but this doesn't change anything. May be SBS changes active directory schema.
