Server Running Very Slow

Firstly.... the server:
POWEREDGE 2800 - XEON 3.2GHZ/2MB 800FSB
4GB SINGLE RANK DDR2 MEMORY (4X1GB)
ADDITIONAL XEON 3.2GHZ/2MB 800FSB, CACHE
ADAPTEC SCSI 39160 CONTROLLER CARD(N)
PERC 4/DC DUAL CHANNEL RAID CARD, 128MB
Hooked upto this is a Powervault Drive Array housing 6 drives (all
15k) as a raid 5 array
The server is acting as the storage for user's home area. We have
around 10,000 users (students), but only around 400 logged on at any
one time.
Basically the server is quite often comming to a standstill. The
users cant login, the ones logged in cannot do anything. We have run
some performance monitoring, and have tried to find out the
problem....but there is so much conflicting information out there
regarding perfmon, and how to resolve the problems.
As I write, the server is running OK as far as the users are
concerned, but the perfmon is showing a graph which resembles
something my 8month old might draw!
For the last 30 minute averages:
Pages/sec Averages:997
Disk Queue Length: 10.2
% Processor Time: 41
Does anyone have any clues about how I can event start to resolve the
problem with this server? How do those stats look to you?
Thanks for any help you can offer.
