You can add Windows NT4 workstations and servers to the domain, but they cannot be domain controllers.
That should be no problem, but make sure that NetBIOS over TCP/IP is enabled at least on your DCs, and you should have a WINS server (used at least by the DCs and the NT4 machines) to make sure the NT4 machines and the DCs will find each other and communicate properly.

you need this extension.

Active Directory Extension for Windows NT 4.0

"Microsoft has developed extensions for the Windows® 95, Windows 98, and Windows NT® 4.0 operating systems that allow those client platforms to take advantage of features provided by the Windows 2000 Active Directory service. These client extensions were developed for customers who want to deploy Windows 2000 Server in environments with Windows 95-, Windows 98-, and Windows NT 4-based client workstations."

hope it helps,

The AD extensions aren't necessary to join an NT4 machine to an AD domain.
NTLM v2 has been available in NT4 since SP4, and the other components in the AD client are just add-ons, but not a requirement.

hmm. have installed sp6a. with ipconfig /all i can see the compuertname.domain. i also can make network connections with my own user/pw. when i try to change the computer from workgroup to domain it says: it's impossible to connect to domain controller. contact your admin to check the account.

useing a german version so the above message is a translation
Do you have a WINS server in your AD domain?
If not, install one on your DC, make sure NetBIOS over TCP/IP is enabled on all your machines, and let your machines point to the WINS server in the TCP/IP configuration.
With the NT4 member, you need to use the NetBIOS domain name to join (enter "set userdomain" in a command window on the DC if you're unsure about this), not the FQDN.

have all needed servers to enter my domain. installed all protocols needed. no effect. changed the hardware - no effect
You're not really answering my questions.
1. Do you have a WINS server installed and running on your DC(s) (is the WINS service showing as running in the Services MMC)?
2. Are all machines in your domain (especially the DCs and the NT4 machine ) pointing to the machine(s) running a WINS server?
3. Are you using the NetBIOS domain name when trying to join the domain?
4. NetBIOS over TCP/IP doesn't require an extra installation; what exactly do you mean with "installed all protocols needed"?
To the basics:
5. Can you ping the DC by name and IP address from the NT4 workstation?
6. Did you install the NIC in NT4 during setup, or did you skip the NIC installation in setup and installed the NIC driver later?
sokiAuthor Commented:
yes, running WINS on my DC and is up. all machines pointing to wins server. installed tcpip and netbios protocol. can ping any ip adress in my domain. installed my NIC later, reapplyed SP6a then
This could be the issue:
> installed my NIC later
NT4 never really recovers completely if TCP/IP isn't installed during setup.
Reinstall from scratch, and when it comes to installing the NIC, choose the Microsoft Loopback Adapter if you can't install the regular NIC drivers (because they need SP6 or whatever.) Once you've installed the physical NIC and assigned an IP address, you can remove the Loopback adapter again.
