DNS Naming

CannonR1

I'm confussed, We have a registered Domain name for the
company, say company.co.uk what should the internal DC be
called? I called it company.co.uk but get wrong host name
errors and no dns server found. Should it be DC1.company.
co.uk or what? Our ISP hosts our web site and is the
primary DNS with no dynamic updating, Just need to get
private internal network up and running ie AD & DC with
internal DNS. Only got 4 servers and 12 pc's cant be that
difficult.

Any help appriciated

Cheers ACE that was exactly what I needed, I have not
done any courses but have read articles and help files
and worked in windows server and desktop environment for
a few years. Got a new job and trying to config the
network from peer-to-peer to AD, on my own. Again cheers,

I will have a read at the links.

If you want to make your AD name the same as your external name, that is
fine.


The domain name, as you stated, apparently is company.co.uk. That's the
domain name. Now you need a host name, such as DC1 or DC or whatever. Then
the FQDN of the machine will be:
dc1.company.co.uk.



You can't use their DNS for AD. Need to use your own internal one. You can
setup DNS on your own domain controller. Do not use the ISP's or numerous
errors will result. If you want efficient Internet resolution, use a
Forwarder. If the forwarding option is grayed out, delete the Root zone.
This shows how to do both:

Keep in mind, using the same internal/external name (called split horizon)
requires additional administrative procedures on your part, such as not
being able to get to your external website by
www.company.uk.co since that
record does not exist on your internal DNS (since you need to point only to
your internal DNS for AD to work correctly). And since the names are the
same, DNS will not forward out name requests for a name that it knows
itauthorative for (meaning that the zone is on that machine). Now if you
want your users to get to your website by
http://company.co.uk, that's a

couple registry chantges to make that work. See what I mean?

Since not being well versed in DNS or AD, I would probably suggest to use a
different internal name, such as:
company.internal
company.co.corp
company.net
company.corp
etc

This way you will not be over burdened with the methods and registry
alterations to make it work properly.

Actually it's not that difficult. Did you read up on the documentation at
Microsoft's site or attend any classes? It's really very easy.

Not to deluge you with reading, but here are some pertinent links that will
help you out.
