How to add a second exchange server to a domain

I have exchange running on a sbs 2003 server, all iwors well.  I have bought another server installed win2003 on it and want to add a second exchange server to it.   I have installed the exchange software but am not sure what to do to configure it so it belongs to the exchange domain and routes messages correctly.

Can someone give me the basic steps needed to get routing to work on the second server...or point me to a technote or something.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

once you install exchange it automatically detects the already present Exchange ORG in the AD and joins it. If you open Exchange system manager you would see two servers listed there. one would be your old one and the other your new server.
create a mailbox on the new server and try to send email to an existing user on the old server.

unfortuanely it is not there in the exchange manager... is there a way to add it manually?
are both these servers in the same AD domain..

is exchange installed on the new 2003 server
Well.. you had mentioned that this is SBS.. i forgot the make a note of that.. my mistake.

The following article states

"When you run Exchange 2003 on a Windows Small Business Server-based network, Exchange 2003 cannot be part of a larger Exchange 2003 organization. Because Windows Small Business Server is installed at the root of the Active Directory forest, you cannot install Exchange 2003 components that belong to an existing Exchange 2003 organization. "

Thanks for that - I am still confused after reading the tech note, perhaps it is the termonolgy used...I am trying to add an exchange server to exisiting domain.  

So in the last sentence it says "you cannot install Exchange 2003 components... " does this mean that b/c it is part of an existing sbs exchange domain no other exchange components (including servers) cant be added to the exsiting sbs domain?

Please clarify.

You cannot add any new exchange server to an existing SBS Exchange setup

Q Can I install the enterprise editions of Exchange Server 2003 or SQL Server 2000 on to Windows Small Business Server 2003?
A. Windows Small Business Server 2003 does not support the installation of enterprise (or upgraded versions) of server technologies on to a Windows Small Business Server 2003 server. As your business needs change, however, you can protect your investment in Windows Small Business Server 2003 by purchasing the transition pack. The transition pack releases the licensing and technology limitations of Windows Small Business Server 2003, but you must purchase and install the technology upgrades yourself.

Exchange Server 2003. Installing an additional Exchange server in a Windows SBS domain is problematic because there is no easy way to replicate information stores between servers in a Windows SBS domain. The servers cannot be clustered, and Windows SBS does not support network load balancing. If your customer absolutely must have redundant Exchange servers, consider purchasing the Transition Pack.

martinmcginley - can you define the exact steps that you went through?

What you should have done was...

1. Install Windows.
2. Install Service pack and the components Exchange requires.
3. Add to domain.
4. Install Exchange
5. Service Pack Exchange.

It has to be the same Windows domain as the SBS server and the machine should not be a domain controller.
