Just making sure - a storm is bad

I'll keep an eye on the switch lights and try to have a look when 
someone reports a problem.

Good idea.

So, I should label each 'computer' on the switch and look at everything 
when there is a problem and pay attention to the 'problem' computer as well.

it will be hard to replace.

But we can run a test with long patch cables to see if that helps.

The main problem is not a small delay in getting a file - 10-15 seconds 
can happen from time to time.  But 5+ minutes is pretty bad.
