Can we recover Exchange 2003 SBS Public Folders from a failed server?

Hi Guys,

Hope you can provide some guidance on this one:

Background:
- Dell Poweredge Server running MS Windows 2003 SBS server patched to Windows 2003 SBS SP1 and Exchange SP1.
- Domain only contained a single server.
- Server ran out of disk space on C:\ and trashed the Windows operating system.
- Exchange database was stored on a separate volume D:\ but the Exchange server application had been installed on C:\
- Public folders were stored as part of C:\Program Files\
- Data on the server was backed up to tape using MS backup but inspection of the tape has shown that the Exchange data was not being backed up correctly, therefore there is no chance of being able to recover the system from backup.
- We have been able to recover the data from the servers HDDs by mounting the HDDs in another server. This data has been copied off to an external HDD.
- Two new larger HDDs (146GB SCSI HDDs) have been fitted to the Dell server and a fresh installation of SBS has been carried out (with a much larger C:\ volume). The server name, domain name and netbios name have been kept the same as the previous build.
- The standard installation of SBS has created a new AD, Exchange setup and Exchange public folders. We have also created new user accounts and Exchange mailboxes for the users.
- We have been able to recover the users Outlook data by converting the Outlook.ost files stored on their PCs into Outlook.pst files and then importing this into their new Exchange mailboxes.
      
Question therefore -
How can we recover the Public folders from the HDD containing the data from the failed build and import that into the new public folder?

an option here would be

1) check whether you have pub1.edb and pub1.stm
2) check whether they are in clean shutdown state using eseutil /mh command
3) if they are in clean shutdown state then dismount the existing public folder store and move its databases to another location
4) copy the old public folder databases in the existing folder and then try to mount the public folder store

the above steps will only work if the exchange ORG and AG name are the same as you had earlier.

Thanks for the feedback on this, I've been waiting for the go-ahead to test this on the server and having worked through it can confirm the following:-

1) We have pub1.edb and pub1.stm files.
2) Using eseutil, the database passed the integrity check.
3) Have shutdown the Public Folder using the Exchange System Manager.
4) Renamed the existing pub1.edb and pub1.stm files .old and copied the other files back into the \Exchsrv\MDBDATA\
5) When I restart the Public folder service I get an error of: C1041724 stating that it cannot restart the Public Folder service.
6) The Windows event viewer also reports the following:-
The information store could not be loaded because the distinguished name (DN) /O=FIRST ORGANIZATION/OU=FIRST ADMINISTRATIVE GROUP/CN=RECIPIENTS/CN= of message database "First Storage Group\Public Folder Store (SERVER)" does not match the DN of directory /O=DWL/OU=FIRST ADMINISTRATIVE GROUP/CN=RECIPIENTS/CN=.

I have shutdown and restarted the Exchange Information Store on the off chance but this did not make any difference.

Is there any easy way to overcome this as I guess it is down to differences in the AD?

Any help would be greatly appreciated.

the error that you have got is due to the fact that exchange configuration has changed.
the ORG and AG names don't match.

Thanks for the additional feedback.

Is there any way to tell what the ORG and AG names are on an existing installation so that we can better prepare for DR in the event of a similar problem happening again.

Better backup software (Symantec Backup Exec V11D SBS is already in place) but this event has taught everyone concerned that you can never be well enough prepared.

The information store could not be loaded because the distinguished name (DN) /O=FIRST ORGANIZATION/OU=FIRST ADMINISTRATIVE GROUP/CN=RECIPIENTS/CN= of message database "First Storage Group\Public Folder Store (SERVER)" does not match the DN of directory /O=DWL/OU=FIRST ADMINISTRATIVE GROUP/CN=RECIPIENTS/CN=.

the above event tells that
event id 1088 in the application log on the exchange server will tell that.
