Help recovering a exchange information store

Hi,
We have inherited a problem server.  The server's raid crashed big time (two simulataneous drive failures).

We have a microsoft backup of the information store, and need to restore it to a new server.  The new server is the same flavour of windows (Windows 2000 SBS), and has been service packed to SP4.

The exchange has not had any service packs applied.

We do not know the original server name, and the domain name is different on the new server.

Is it possible to restore the backup at this point or should I go home and drink some Vodka?  Can anyone help me or point me in the right direction.

Thanks all....

A 2 drive failure should still be recoverable but clearly the company you used couldnt do it.

Can you not find out the old servers name from the client pc's dns cache? If you have that the the mailbox store and information groups names can be worked out.

you would need to know the exchange ORG and AG name for the backup to work fine.
if you can get the priv1.edb of the backup tape then you can run the following command against the database to find out the ORG and AG name

find "ou=" priv1.edb

I can find out the name tomorrow, but cant get anything out of the backupp.  

The backup is a file on a drive not the tape, and is the information sotre rther than the files.

I understand all this, but as we can't seem to get the edb's out of the backup, which appears to contain the "information store" rather than files, then i don't know what we can do.

I think i might need to ask a different question "How do i extract an information store from a msbackup"

We have used a product called ontrack powercontrols http://www.ontrackpowercontrols.co.uk/  which will read directly from the database files, it can generate pst files from the store that can then be re imported to the new exchange box.

It costs some money but if you have been down the data recovery route the data must be important. I have got data from a backup of the priv1.edb and stm (both with and without log files) and direct from an NT backup. It has got me out of trouble several times times with servers that have either died completly or had the IS to damaged to mount. The first time i used it was in a dual RAID 5 failure...

You should just be doing a restore, selecting the .bkf file, drilling down into it and selecting the files you need. Its should be simple, whats the problem your having doing that?

The backup is a backup of the "information store" which i believe may well be an "online backup"  it does not consist of any "ebd" or "log" files on a drill down I get three options:-

logs
Mailbox Store
Public folders

When I have selected these I then get a message saying i have chosen to restore an information store.

Durge:
We have similar software, but until I can get the restore off the tape, i can't use it. See comments above about the backup.

UPDATE:

At the moment:-
There is no original AD.
I have a new server with Windows 2000 SBS installed with the same server name as the old server.
I have a working information store on the new server
I have a backup created with Microsofts Backup of the information store, not the individual database files.
I can not restore this backup, it just stops straight away.

OK in the restore logs what does it say?

Also on your information store , drill down to the mailbox store, get the properties and make sure "allow this database to be overwritten" is selected, do the same for the Public folders.

Nothing is being listed in the logs, or either of the stores.

I have just managed to get a restore working, it seems we were having a blond moment and had forgotten to "Dismount" the store on the running exchange server.  Restore is happening as we speak.

The logs I was referring to were the actual logs created by msbackup mate but not to worry. ALso you could have overwritten the stores while mounted if you had allowed them to be overwritten.

Sorry it's the sun effecting me.  The logs were fairly undescriptive, according to my chap trying to do this.  Did not see a setting to overwrite, but I will look for future reference, however I hope not to be having do this again ;-)

I was having ablonde momnet too, you do need to dismount them but because you are restoring them to a new location (i.e a new server despite having the same servername the GUID will differ) you need to make them overwriteable.. heres how:

I think this restore may fail if this isnt setup, if not then brilliant.
