AD vs. DNS Namespace

[leeym]

When installing Windows Server 2003, I created an AD namespace called, for example, "mycompany.local." By default, the DNS namesapce is the same. How can I change it so that it reflects my actual domain name such as "mycompany.com."

Thanks

DCPRomo the machine and remove AD and then start over. This is why you should always plan ahead before creating your AD. Whatever you call the domain name will be your DNS namespace.

hmmm, ok.

The reason why I ask is because Exchange will go on the same box, and if the DNS namespace is called "mycompany.local" and it's doesn't include a top level domain, it won't be recognized. Make sense?

Exchange can use mycompany.local for it's internal routing and routing to other exchange servers but not for routing out to the internet. You would have to create a new recipient policy in Exchange to make all your user accounts get the mycompany.com dns names in their email addresses.

Using mycompany.com from the start will set that automatically when you install Exchange.

How do you create a "New Member Policy"

Thanks for your help

It's been about 6 months since I looked at Exchange 2k and up. Open up the Exchange Manager and open help search for New Recipient Policy. That should tell you where it is.

Also don't forget you need to point the MX record for mycompany.com to whichever Exchange server has the SMTP connector on it.

Thanks man. I've done all you suggested, but so far I can only send and receive message between users with the domain, "@mycompany.local"

My MX record is all set I think. Any other ideas? Thanks

is your domain pointint to your ip address?

Actually my domain points from the registrar to NO-IP.com (this is a temporary solution) since all we have is a dynamic IP.

Anyways, NO-IP is configured to see our dynamic IP (via a client app on the server), and they have our mx record as well. I've double checked port forwarding on the firewall, and all is well.

Thoughts?
