I don't know your future plan of adding more servers, but basically it's not suggested to run Exchange on a DC. You can add this server as a DC, transfer all the FSMO roles from the Exchange box to the new one, then demote the Exchage as DC. It's better to later add another server as a second DC. Hope this helps.

You don't want Exchange on DC (you can google it, lots of problems, a quick one here Try avoid that as much as possible.
Transfering FSMO roles is much easier than install a second Exchange server then move mailboxes.
So my suggestion is
1. Add the new server as the second DC.
2. After AD replication, transfer the 5 FSMO roles from the first DC (Exchange server) to the new added server.
3. Demote the Exchange server so it's NOT a DC any more (Exchange still running on it).
4. Now your AD has only one DC. Later if you have another server, add it as another DC for fault tolerant.

Install OS on the new server install all updates and SPs, add server to existing domain, follow the instructions in link below to add addition DC to existing domain.

Transfer all FSMO roles to new DC see link below

You now have  a domain with two DCs primary being the new server without Exchange.

Now build new server update add to domain install Exchange do not DCPromo this server

Install Exchange
Replicate Public folders
Move mailboxes

Leave the first exchange server running for a couple of weeks so Outlook clients swicth to new server

uninstall exchange from server

You end up with 2 DCs
one Exchange server on a member server not a DC

You should step through one item at a time.
Add a second server to the network making it a DC. The AD schema will replicate from the existing DC to the NEw DC.
You might want to explore using vbscript that add users to AD and also create exchange mailbox.

Your replies makes lot sof sense to me but there is one more problem that Primary/First DC is having trust relation with another domain   .  Although this trus is outbound and only with domain name not the computer name so should i presume that second DC with all 5 FSMO roles on it can have trust relation ship intact withe another domain and i dont need to create trust relation ship again with the second  and also DC with all 5 FSMo roles , that was why i have planned keep intact my first DC and just move mailboxes to another new EXchnage server 2003

please advice

And thanks all of you for your suggestions and replies

Trust relationship will stay once the DCs are fully replicated.

Thanks , I added second DC successfully and transferred roles as well which is very good

Now what I have to do to enable second DC to create user with mail boxes , because when i tried creating user  it didn't went further to create mailbox for the user.

Should i have to extend schema to the new DC although it is the owner of all five FSMO roles including schema master

Please advice

All You need is to install the Exchange system management tools on the new DC.
To do this, run Exchange Server 2003 Setup (using the Exchange cd, run on the new DC).
On the Component Selection page, set the installation action to Custom, and then click Microsoft Exchange System Management Tools.
