Client failed to loggon to Server

Hi all,

I'm trying to create Server-Client
For Server i'm using Windows Server 2003 and Client is Windows ME I've been successfully to create actrive directory but when client try to logon i got this message "This domain is invalid ...." or some thing:(

Of course, I've created user & computer.
Let's see what i have done

1. after finished an installation I have set an IP address to 192.168.0.1, DNS 192.168.0.1 defualt gateway 192.168.0.1
2. then I create Active directory
3. then i create user account and computer account
4. For client i set defualt gateway to 192.168.0.1 and I set DNS to Enable Host=server1 domain=wpserver.com
5. after all of above i try to logon from client but failed

What's wrong?
Do i need to set anymore?

Thanks for advance:confused:
