My 2-year old mail server started crashing with BSOD about 2 months ago, and every time you check memorydump it says "Probably caused by : iaStor.sys ( iaStor+4b676 )".
Initially it ran with Intel Storage manager version 8.6, then I upgraded to 8.8, today it's at 8.9, still same problem.
Server is Tyan, out of warranty. Latest BIOS.
Windows Update is not working right now, but should be fairly up to date.
RAID is 1 (main data) and 0 (backup), 4 750GB drives total.
It runs Exchange 2007, Sharepoint v3 and Backup Exec V12.5.
As far as I know nothing changed - no drivers, no software, no hardware. I tried updating everything I could find (software-wise), no dice.
Everytime it crashes like that Intel starts rebuilding the Mirror. Data doesn't seem to be affected.
Server can go as little as 1.5 hours and as long as 1 week between crashes. Last data is 15 BSODs in a month.
Tried researching via google, via intel's site, tried disabling 1 USB which had same IRQ as Intel controller, updated BIOS, nothing.
