Hi Albert,
I had the similar problem some time ago. If you go to MS webcasts site (I do
not have the internet connection right now, only to the local ISP and SMTP, so
I can't tell the URL) you will find 2 or 3 webcasts that deal with the possible
causes and solutions to this problem. You should read the transcripts of all of
them. I tried to fix it with repair, defragment and isinteg check and I did but
for short period of time, only. Hopefully I had a spare server and I moved my
stores to it. Since then the problem has not reappered.
Good luck
Zoran

Subject: [exchangelist] Problem backuping exchange 2000 database
http://www.MSExchange.org/
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.

Information Store (2264) Online defragmentation of database 'D:\Exchange

error -1018. The next time online defragmentation is started on this
database, it will resume from the point of interruption.

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.
