I need to know how to set up the following Active Directory design on a single Windows Server 2003 Standard Edition server.

1. I need to create an AD root domain (company.com) -- this i know how to do.
2. On the same server, I need to create the AD sub-domain office1.company.com.
3. I will then add other AD servers as subdomains office2, office 3, etc. -- this i also know how to do

I cannot seem to figure out, or find out if it's possible, to have both an Active Directory root domain and subdomain on a single server.

Any help will be much appreciated.

Thanks,
Steve

this cannot be done, in order to have a sub-domain you have to add another DC to be the DC of the sub-domain.

and there's no way to have 2 DCs on a single machine, correct?

So if I was to set up several DCs as office1.company.com office2.company.com, etc, and not have a DC for company.com. Where would I have to have the DNS MX record for company.com resolve to (I will be using Exchange Server 2003 for email)? Exchange Server will be running on the DC at each location.

Basically, how could I set it up so I could send an email from the outside world to user@company.com and have the email reach the user who logs into the domain as user@office1.company.com?

you have to have at least one DC for each domain (by domain i mean both root domains and sub-domains).  So you would have to have a DC for company.com, another DC for office1.company.com and another DC for office2.company.com.

people sending email from the outside is really totally seperate from your internal domain name. for example you could have your windows domain named company88.com and your public domain named company11.com and your users would get mail that was sent to company11.com even though your windows domain was named company88.com.

the point is that you have to have the reciepent policy set to "listen" for email being sent to whatever your publically registered DNS domain name is.  You do this in exchange system manager.  And also you have to have your MX record pointing to your mail server. thats really it.
