Test project.Installed Parent domain with two
domain controllers.Second controller which I installed yesterday is where I installed Exchange2000.Emulated a child domain, called it HQ.domain.edu where second Exchange server is running.I am able to forward mail from client on hq.domain.edu to domain.edu but not vice versa or send reply.The error is quote"message was rejected by server & e-mail recepient.error 550,unable to relay to address.Server error"In essense I am trying to connect two sitesala ex 5.5.My parent domain is acting as root server which I will have to change.When I try to include an MX record to point to hq.domain.edu server,I am unable because it is accepting only servers on domain.edu.Also unable to manually edit the database to include hq.domain.edu.Any thoughts will be welcome,Thanx

Check the IMS in exchange, under the routing tab. (connections/Internet mail service/routing)

Make sure that the hq.domain.edu is listed in the "reroute incoming smtp mail". Since both domains are using the same mail server choose inbound only.If there are 2 mail servers on different domains you will need to choose relay.

This is also a good place to go over mail relaying. Look down to where it says routing restrictions, choose clients that sucessfully authenticate. That will stop people from relaying other mail thru your server.

Good luck.

Gotcha now.

I'm just going to go over then how I would of have set it up then let me know whether or not you went about it the same way and what steps you took.

Luckily it is just a lab, a perfect place for trial and error.

I would have 6 machines. 2 - dc's, 2- exch srvs, and 2 client machines. All running 2k.

Both dc's are GC servers. Each exch server is running on just a member server for that domain.

I install my first exchange server in the root domain of the tree. Installthe IMS, make some containers and multiple mailboxes, and test the transfer of mail between mailboxes.

Next I check the permissions for the exchnage site.
(here I would make a 1 enterprise exchnage admin group and 2 domain exchange admin groups and apply them appropiately to each section)

Next I would install the second mail server for the child domain of the tree. When Install it I would add it into an existing exchange site.

You should be able to see both servers from the same exchadmin window.

In the IMS/routing for each server add the appropiate domain as "Inbound".

Note, you should have a seperate IMS for each server.

Make a mailbox on that server. Log in to the 2nd mail server from the client machine in the child domain. Go ahead and send a piece of mail to a person in the domain. It should transfer.

There should be no need for site links because they are both in the same site and they each know about each other.

Again this is just how I would of have set it up. By no means is this the only way, but I have seen that this is the easiest way (at least for me).

Let me know the steps you took to configure yours.

Hello darkoverlord,Ihave gone that route prior to posting on the site,although I will give it another go.NB this is a home project to learn win2k & Exchange2000 & 2 independant exchange servers are running in each domain 1)domain.edu & 2)hq.domain.edu.
