We had a server loaded as folows:-

c: exchange system files
d: database
e: logs

The server crashed and I had to reload the c: drive, but kept D and E intact. How do I create the storage groups, databases and logs back in the exchange program?

Thanks.

Simple run the setup.exe /disasterrecovery switch - it would bring back all the setting which were there before the server crashed - also includes Exchange to point at D and E drives respectively for their storage group and database.

Would this work now as I have done a normal install? Shall I uninstall and run the disaster recovery command?
Thanks

Ok, this gets a bit crazy - you had an exchange server and it crashed - now you did a fresh install.

Am i missing something ??? did you rename the box ?? or was this your only DC ???

If you have named the box the same name - Exchange wont let you perform a fresh install - it would allow you to re-install - if this option is selected - you would already have all the information in your exchange system manager.

It has all the infromation apart from the storage group etc. I searched on the net and it told you to delete the exchange server information to allow a fresh install. Can you not just point it at the database on the d drive then?

Ok tell me something did Exchange exist on this same box earlier ?
Are you familiar with the tool adsiedit ?

Look i am trying to save your time in order to uninstall and re-install - so hope you understand this barrage of questions coming your way.

Perfect then i want you to open adsiedit and drill down to configuration - services - Microsoft Exchange - organization (ensure this is the same as earlier) - administrative group - servers (how many do you see here) - your existing server - information store - storage group (do you see this ?? )

I am stumped to see how the data from configuration partition blew off - this is something not real - at least in all these years of troubleshooting a simple exchange server crash would never touch config partition.

Also, you mentioned that you did a fresh install - this should have created the storage group and stores.

I would recommend two action plans.
1) Manually create storage group and stores (with default names) and try your restore.
2) Else take the longer route - perform a clean install - and work with restore.

I have just tried creating a brand new storage group, created a recovery storage group and copied the old database in. The exchange server will not mount this though as a recovery database. Is this a way of recovering?
Thanks

If you have your new storage group and stores in place - why working with RSG.
Ensure that you point your Storage group and stores using ESM to your default location (D and E Drive)
Do not mount your stores at the moment.
Run the command Eseutil / mh "path to your database .edb" - check for the state of the database for "clean shutdown" and log file required "0-0"
If this the situation please do not place any log files in the log file folder - place them some where else.
Now, you can comfortably mount your stores.

Ok , I am getting nearer now. I have managed to mount the old database in the storage recovery group and can see the old email databases but when I try and merge I get the attached error.
