Exchange 2000: Slow POP3, constant disk access, can't dismount.

I have 2 varities of users.  Some use Outlook and the Exchange Service while others use Outlook and the Internet Mail Service.  My users that connect via Outlook/Exchange Service have no problems, but those who use POP3 report SLOW mail delivery.  Even if no IN/OUT mail exists the delivery message can stay on the screen for 60 seconds.  Another problem I have noticed is the Hard Disk Activity LED rapidly blinks all day long.....non stop.  I keep the BADMAIL folders empty in all 5 VSI folders.  I have verified that I am not SPAMMING anyone via Relaying, but I am at a loss.  My 3rd problem is I seem to no longer have the ability to DISMOUNT either of the 2 stores.  They will get to 66% and stop all while the Hard Disk LED rapidly blinks.  It stays that way for 15 minutes before I just do a START/SHUTDOWN.  I guess it could be taking longer than 10 minutes, but it has never taken that long before.  After reboot everything mounts with no problems and the hard disk LED returns to the rapid blinking.

My configuration is:
Dell PowerEdge 2400
Intel P3 733mhz
2GB Ram
4-SCSI Hard Disks in a RAID 5 array (I verified I do not have a dead drive.)
Network Associates GroupWARE Virus Scanner (McAffee)
Windows 2000 Server  SP4
Exchange 2000 SP3 (No POST-SP3/pre-SP4 patches installed)

Perhaps time to bust out perfmon... you mentione the HD enough times that it sounds like you are already concerned about it.

Also, your transactions logs run ALOT better when they are NOT on raid5 sets... should use mirrored sets for these logs. This is well documented.

My problem turned out to be the MAILBOX Store.  I had 11 users that had issues.  2 had Non-Delivery statements exceed 100MB a piece and the others were SPAMMED over 4,000 times.  Wiped their INBOX's and all is well.

Jason thanks for the advice to use PERFMON and to add both RAID1/RAID5 arrays in my new server for next year.
