Exchange Server Database Restore.

By chris_s_cooper ·
Scenario:
Microsoft Exchange Server is loaded onto a Primary Domain Controller, the only server in the network. On a nightly basis the server is backed up using Arcserve and a internal Dat tape drive.

The building the server resides in burnsto the ground, now I have to restore the MS Exchange database to the New PDC or new server.

The following is from and MS Exchange Sever Book:

All the administration access rights information on the Exchange Server is stored in the Directory database. The administration rights are always defined to a certain NT user security identifier (SID). Because the SIDs are unique and will never be reused after they are deleted, you should always have a backup of the NT operation system files,as well as Exchange files. If for some reason you have to restore a whole directory database, you will not be able to start any services if you do not have access to the same domain database that the original server was using---that is, if you cannot use the same user account (the same SID) to start and administer the service. Therefore, it is highly risky to install the Exchange Server onto a PDC in a domain with no Backup Domain Controllers; if you happen to lose the machine, you will lose the domain database, and will not be able to restore your directory database and use it.

How can this restore successfully be done without adding any new hardware and without remote backup of the system. We only have a new server and the Dat tape from the original PDC.
I thought we may be able to load the Directory database from tape, then associate the back-up Administrator id to the Exchange services and restore the Exchange database. My thoughts are only speculation.

Restore NT first. That would include the security info. (If you regularly run RDISK, you should have a SAM backup there too if it's not too big!)

Then restore the Exchange files and expect the services to start....

Here is a little work around:
Reinstall your PDC with the same domain name and computer name. Re-create your Exchange Service Account. Install Exchange making sure to use the (exact) same organization and site name. Restore ONLY the information stores (priv.edb and pub.edb). Run isinteg -patch.
Open the Exchange Admin program and select your server and chose properties. On the Advanced Tab select the Consistancy Adjuster. Chose the first option to synch the directory and make directory entries for mailboxes.
This will restore the dir.edb with all your users. You will need to recreate their NT account and re-associate it to the Exchange Mailbox.
