How to join a PC to a Domaine

I have a windows 2003 domain  controller and 15 windows xp pro workstations. I am having difficulty joining my PC to the domaine. With WIndows XP Pro, in order to join the domain, do you have to indetify the NetBios Name of the domain, or the DOmaine Name or the Fully Qualified domain name of the DC.  The only thing that is working for me is entering the netbios name. Maybe I dont understand the difference, can someone explain ?

Domains do mot use Netbios names, only computers.  How did you name your Domain? or domain.local?

The name of my domaine is, the netbiosname that we were given is anishnabe-ls. When I try to register the PC to the domaine I can only do it when I enter anishnave-ls as the domaine name ?

Do you have DNS configured on the server with the  DNSservers IP address set on the client machines?

Here is a tutuorial on DNS so you can ck it..: logon or join the domain

Also, make sure you point your DSN entry on the workstations in the tcp/ip properties to your internal DNS server first before joining your pc to the domain.  There should only be 1 entry in the DNS entry and that should be your internal one.

DNS and Active Directory rely heavily on each other.  They must both be healthy for your network to work properly.

If you dont have DNS configured, Windows network machines will use the browser service for locating devices.
A DNS server manages a domain or multiple domains depending on the network and use you have for it.
In your circumstances it would manage your 1 domain, when the client machines have a request to join the domain it would look for the DNS server for that domain first.(which is why you put its IP address as your primary DNS server to speed things up). Once found it would then query it for a particular name and related service/record, the DNS server would then resolve this to an IP address for communications. In this case It would be looking for the DNS server then the record for the location of Active Directory to join the machines and create a computer account.

There are characters limitations with netbios names, which is prob why typing half of the domain in is allowing the computer to join.
To use the DNS name you need to have a DNS server setup to manage the domain and integrate with active directory.
Go to Administrative Tools and see if you have an Icon for DNS here

It should have also warned you if you didn't have DNS installed when you were installing AD and asked if you would like to setup DNS there.
