exchange 2003 recovery

Hi guys needs an urgent help and your views

we got raid failure on the dc and server crashed, unfortunately this was the domain controler and we donot have system state backup. New DC is setup and about to be moved to the site;
Now we have exchange 2003 running on a member server, how we can get this exchange working. One thing which i have in mind is that take offline backup of database with logs and everything and build new exchange and over write the old database on to new, but i am not sure if that will work as we have set up a fresh domain controler;
please suggest if there are other things needs to be done while performing above task. And if any one had a different idea or suggestion please let me know. this has to be up today

thanks in advance
Rajeev

so to sum this up.
do you have a backup of any of your DC which are also global catalogs?
do you have a backup of the exchange databases?

are you having to recreate all the ad domain and forest from scratch and re create the users?

And also if you can let me know if there is a way to run exmerge to make pst of mail boxes as DC is not in place where as i have exchange logged in as an administrator account prior to crash and that session is still active.

you wont be able to exmerge because there is no DC and Global catalog which the exchange server has access to.

looks like you will have to:
deploy a new DC.
add all the users manually as you have no backup.
on another server install exchange 2003 in to this new forest.
dont use the /disasterrecovery switch as this wont be anly use as its a fresh forest.
use the same Servername as the old one, same exchange organisation, administrative group, storage group and mailbox store name so it is a total mirror of the old server.
install all the patches and SP so it is the same patch level as the old server.
make sure the logs, databases, check file etc is in the same drive and location as the old server.
copy the logs to the same place on the new server. and chk file and dbs.
try to mount the database

BertlingCommented:
why are you uninstalling the old exchange server? i though this server is now on its own and there is no DC within this exchange org?? you dont need to remove it.
