I have a really tough job at hands.


We had Exchange 5.0, installed at a WindowsNT Server 4.0 with service pack 5
installed. The Information and Directory store were on one partition of the
disk and the logs were on other partition. The hard disk failed.
Unfortunately, there was no backup taken for 10 days. (No backup at all!).
Somehow, it was managed that the PRIV.EDB and PUB.EDB could be retrieved
from the crashed hard drive. Only these two files were managed to be

PRIV.EDB is 3 GB of size and PUB.EDB is 1 MB in size. 

But the person at that time were not able to get it working. I have been
trying to restore the same.

What I have done?

1. Installed NT 4.0 with service pack 5 at some other machine (NT server as
PDC for some test domain)
2. Installed Exchange 5.0 on the machine. 
3. Stopped the Information Store service of Exchange and copied the PRIV.EDB
abd PUB.EDB file into the MDBDATA directory. In the MDBDATA directory only
these two files were left. All the logs were deleted.

4. Changed to exchsrvr\bin directory and ran ISINTEG -PATCH . 

This gives a warning: Warning, The Private Information Store could not be
found. Assuming -Public -Only
Now if I try to run the information store service, it terminates with the
sevrice specific error: 4294966095, which is described as  -1201 0xFFFFFB4F
JET_errDatabaseDuplicate      Database already exists            4294966095
in Microsoft references.

If I try to run "edbutil /d /r /ispriv /tx:\tempdfg.edb, then says,
operation terminated with error: 550.

                    edbutil /d /r /ispub /tx:\tempdfg.edb runs successfully.

I have found out the state of the PRIV.EDB. It is in the Inconsistent State.

I have no way now.

Could any of you guys help me!
