[K12OSN] Big Troubles

[Mark Gumprecht]

Jim,
On top of what jim wrote, if the problem is at the server, go over the 
/var/log/messages and other logs to see if there are any out of the norm 
messages. I had a problem with a SCSI controller that dropped off 
line,RAID 0, and there was a one liner in the message log that I missed 
that would have saved me a 20 mile drive to the site. Also, depending on 
the hardware, If you have diags, run them. I tend towards dells, partly 
because of the diagnostic software that comes standard. A few starting 
points.
