Hi,

We have Exchange 2003 sp2 on Server 2003 sp1, around 40 mailboxes in one store. 
Store size is currently around 12Gb with 18Gb limit.

We have just moved exchange to a new dual processor machine with 4gb of memory, 
due to previous hardware being too slow and the exchange database kept getting 
corrupted - had several PSS cases to get over that.

We now schedule nightly, outside exchange 'maintenance' and backup times, the 
running of eseutil for checksum and integrity checks. Once a week we also do a 
'defrag' of database using eseutil.

The last defrag failed with: Operation terminated with error -327 
(JET_errBadPageLink, Database corrupted) after 794.109 seconds. (déjà vu) - it 
had been running cleanly for only three weeks.

It is really frustrating that the database keeps being corrupted, I can find no 
reason for this outside of exchange, there is no antivirus product on server 
except for one that integrates with Exchange so it's not local files being 
scanned at wrong times.

Anyway, it would be good if I could run ISINTEG with fix flag nightly to detect 
errors early and correct them.  But I can not find out how to run it 
non-interactively.  Is there a way I can add isinteg to batch file and have it 
run?   Tied in with this is that I have to dismount the store from the batch 
file first - is there a way to do this from a batch file?

Thanks for any insight or help you can provide me.


Incidentally, does anyone have any ideas on what could cause db corruption?  Is 
it just that it is still a 'jet' database underneath it all and they are just 
flaky and backward? After all, they can't even do an online integrity check in 
2006! I admit this whole experience has made me rather cynical of exchange in 
general, but we're locked in now :(  so just trying to get the thing to behave. 
Pity obsolescence made us upgrade from Exchange 5.5 - that ran flawlessly for 
over 6 years.


Regards,
  Bryce Stenberg.
