    right we know the Active directory namespace and DNS namespace overlap right?

    Now im trying to understand the terms sub domain and child domain... if i have it correct - a child domain is a "branch" of subdomain?

    accounts.contoso.local - being the sub-domain
    income.accounts.contoso.local - being the child domain

    is it just terminalogy? :blink

    Zim,

    The sub domains start from the root of the full domain name.

    For example www.contoso.com starts from a . (dot) at the end of .com and works back from there.

    So in order it it...

    . (root domain)
    com
    contoso
    www

    Also you might see http://mail.contonso.com as a URL so this would be referred to as the mail sub domain of the contoso domain as apposed to the www sub domain. It is handy to know this terminology when you are working with DNS as you would probably want the www sub domain to point at your web server and the mail sub-domain to point at the Exchange server.

    In regard to a child domain you just have to make sure it is in the same contiguous namespace as the parent domain name. So if the parent domain is contoso.local then accounts.contoso.local would be fine.

    Hope this helps! :biggrin

    ...except www isn't a domain or subdomain - it's a computer in the domain. Anything to the right of that computer name are subdomains, the domain, and the top-level domain (.com, .net, etc.)

    www is a computer? :blink

    I was under the impression when you buy a domain (lets say contoso.com) the you can have sub domains such as www, mail, webmail, crm etc etc.

    Therefore the domain you have is contoso.com and some of the subdomains you can add could be...

    https://www.contoso.com
    http://mail.contoso.com
    http://webmail.contoso.com
    http://crm.contoso.com

    As I see it it's a bit like UNC but backwards.

    i.e. \\sillyserv\share works forwards, like the way a sentence is written (in the western way anyhow).

    The domain starts with a . which is the root, but because all domains (I hope, shoot me guys) start with it we leave it out.

    So, we have .com.micro$oft.www

    So it's 'backwards'.

    If we didn't do it that way we'd be in all sorts of sh*t to differentiate between LANS and WANS.

    Wotja fink y'all, am I anywhere near? :eek:

    Yes, it is. WWW defaults to the default Web server for the domain. Mail.contoso.com indicates the server named mail on the contoso.com domain. Webmail indicates the server named webmail on the contoso.com domain. Same with crm.contoso.com. Those aren't subdomains. Those are server names or aliases for servers.

    Yes, you can have subdomains. For instance, you could have mail.east.contoso.com. Mail would be the server name on the east.contoso.com domain, and east is a subdomain (or child domain) of contoso.com.

    Yep, it's just terminology. I've heard subdomain and child domain used interchangeably.

    From what I've studied, yes. Someone else might have a different opinion.

    But does it matter what they call them? Don't get overly bogged down in the terminology. You understand the concept, right? :)

    Just keep doing what your doing but whilst you are doing that, remember this is one of the most interesting studying times you are going to be faced with. Sure, there is a lot of new stuff to jam into your noggin but that stuff is gold, so just enjoy the ride and be done with it. Book the exam once you feel nearly ready, that will give your the motivation to really get stuck in, so that you can slay the beast.

    Have you finished all the chapters in the MS Press book? If you add WSUS to that (depending on what version of the book you have) then you should be ready to go. It is a challenging exam but its good feeling when you pass! :biggrin
