Setting up Domain

I may end up posting a few questions I dont understand so please bare with me.

When I see information about setting up domains they normally name the domain something to the effect of Win2k3forest.ads

Now, my company has something to the same effect.
But what is with deal with the ".ads" must I have something like that when setting up the domain or can I just put Win2k3forest?

Thanks,
Cess

In AD, you need to use a fully qualified domain name, because AD uses DNS by default rather than the older netbios and wins.

So a fully qualified domain name has to have a ".XXX" on the end of it?
Stupid smelly XXXXing A dns!!

Yeah, but it beats the crud out of NT4 domains and their 15 character limit on names. Try running a domain with 5000 computers/users and some sort of standard naming convention on that!

It is possible to use a single label domain, but it is not recommended, to the point of practically not being supported. Use at least two labels to your domain name. MS recommends (and so do I) that you do not share the namespace with the internet. This can be nearly guaranteed by using LOCAL as your first level label.
Or, you can make your AD domain a child of an internet domain that is registered to you. Such as AD.mycompany.com, W2K3.mycompany.com, intranet.mycompany.com, etc.
