I got a server crash last week and I had to reinstall the OS. I
reinstalled Exchange with the /DisasterRecovery switch and installed the
service pack 3 and the following rollup patch. I mounted my databases
(that was on another partition). All went OK. No user complained about
data loss.
The server is running Windows 2000 Server and Exchange 2000 standard.
Yesturday, I observed that my backups were not performing correctly.
I also got events in the event viewer:
Source ESE
EventID 474
Description:
Information Store (2264) The database page read from the file
"D:\Exchange Databases\pub1.edb" at offset 1010651136
(0x000000003c3d5000) for 4096 (0x00001000) bytes failed verification due
to a page checksum mismatch. The expected checksum was 3243529293
(0xc154544d) and the actual checksum was 3377747021 (0xc954544d). The
read operation will fail with error -1018 (0xfffffc06). If this
condition persists then please restore the database from a previous
backup.

I read on Microsoft web site that I should restore my database from a
previous backup, but since none of my recent backups are working
correctly, restoring the previous working backup will give me a data
lost, which is not acceptable.
As an alternate procedure, Microsoft article mention to use the ESEUTIL
and insinteg utilities to fix the database after moving the mailboxes to
a different server.
Is this will solve my database issue or is it preferable to create a new
database for this server (after moving the mailboxes and public
folders)?
Is there another way to fix the issue?
Any advice would be appreciated.
