Exchange installed with disasterrecovery switch, will pick up directory 
information from AD. since exchange 2000 and above does not have its own 
directory , all the information is stored in the AD. 

If your exchange crashed and the crashed server is not a DC you could start a 
server from a start and run setup /disasterrecovery and bingo you have your 
original exchange server settings , AGs and attributes as before. Once this is 
done , restore the database from the back up. Mostly all your user account 
would be mapped with the appropriate mailboxes. 

If it does not happen , you have to use a MBCON tool to do the same(when users 
are more, and manually reconnecting will be a hell of a job). Even if your 
exchange server was on a DC still you could do so, provided if you have other 
DC's in the network. 

The other DC's will also be containing the replicated information from the 
Exchange DC.

If you are using disasterrecovery switch then you need not remove the exchange 
server manually.
