Hopeless situation?

A PDC and a DC running an internal domain.
The DC had Exchange 2000 server (on a separate partition) which dived.
I built a second DC and did a disaster recovery which worked.  I backed up the information store.
I then rebuilt the first DC, but it refused to restore the backup (from the 2nd DC) after disaster recovery.
Now the PDC has also bombed, and I'm having to rebuild it since restores of system state are not working.

My question:
Given that the entire domain, including Active Directory, has had to be rebuilt from scratch, is it still possible to recover the information store?

More info on request... sorry, but E2K is not my forte and I'm beginning to wish I'd never installed the thing tin the first place...

As long as you have a backup of the information store that is good, you should be able to recover all emails. You will however, need to use the same EXACT organization name, and administrative group name as you had on the original installation. Meaning, that when you recreate your domain, and are ready to install Exchange, you should then use the same info as you did before. If the organization name and/or the administrative group name is different, you will not be able to restore the information store and recover the emails.

After you have rebuilt the domain and all users, installed Exchange and restored the information store, all you have to do is run the cleanup agent against the mailboxes, and reconnect them to their associated Active Directory accounts that you have created.....

So basically, if you have the information store backed up, you will TOTALLY be able to recover the emails....

1. Recreate the domain (install DC, create users etc..)
2. Install Exchange using the same Exact Organization and Administrative Group name as the first install
3. Apply the same service packs and hotfixes to Exchange as you had prior (Same for O.S.)
4. Restore the information store from backup
5. Go into ESM, right click on the mailboxes container under the mailbox store and click on Run Cleanup Agent

After this, all mailboxes will have a Red X next to them meaning they are disassociated.

6. Grab the utility called MBCONN from the service pack 2 cd, and reconnect all mailboxes to the proper A.D. accounts...

More clarification or instructions provided upon request...


P.S. - Don't like Exchange 2000?? Look how recoverable and fault tolerant it is!!

Hope this helps!!
