Exchange 2003 Recovery

I have Exchange Server 2003 installed on Windows 2003 server. The server had hardware issue, but we recovered MDBDATA folder.

Now need to restore the same, we set another server with same windows 2003 and exchange 2003 version.
copied the MDBDATA from recovered to new one.

How do I start the exchange recovery after that

If the server failed, then you should have built a new Windows server with the same name. RESET the computer account on the domain and then installed Exchange using the serverrecovery switch. You can then use the existing databases.
Exchange 2003 doesn't have database portability, so you need to have the server identical to the original.
If you built a new server with a new name, then you are going to have to build another server. Removing Exchange or renaming the new server isn't going to work.

I will be blunt - did you actually read anything about doing DR before randomly deleting stuff from the domain? You have made the job significantly harder than it was before.

The database maybe mountable, but it will be with a lot of errors. You will need to mount it in a recovery storage group, then use that method to extract the data and put it in to new mailboxes.
Of course you will have to adjust all of the mailboxes for the new database.

If Exchange 2003 was still supported, I would tell you to call Microsoft.
As it is not, you really need to engage a consultant. This kind of recovery is too complex to be covered by a forum.
The other option is to use a third party tool to extract the content from the raw files. I refuse to recommend any of them unfortunately as they all spam forums and newsgroups (or their affiliates do), buy reviews and generally have the ethics of a used car salesman from the 1970s.

If you hadn't deleted the computer account from AD, then it would be a pretty straight forward DR.

If you can restore the EDB file I would recommend using Exchange Recovery from Kernal Data Recovery. You will be able to export the mailboxes to PST and then you can bring up a new Exchange server and resotre them back into the database.

in fact we have all mailboxes in local psts. i did this try yesterday and we got the data recovered today only.

action done so far

1) Installed OS 2003 , with updates
2) Tried joining domain but thrown error as "account already exists" - hence went to AD deleted that computer account
3) installed exchange in DR switch mode
4) copied folder MDBDATA from USB HDD to exchange server location

in fact last few more files copying going on

please let me know

"Tried joining domain but thrown error as "account already exists" - hence went to AD deleted that computer account"

That was the error - what you should have done was RESET the computer account, rather than delete it. It would have allowed you to join the domain at that point.

in case if i have system state backup of AD and Exchange , then will any use
Simon Butler (Sembee)ConsultantCommented:
The problem with using a system state recovery is that will put you back to the point of the system state backup. That means ANY changes to the domain are going to be lost.

Therefore a third party tool would be a better option, along with a strong recommendation to move to something that is currently supported.
