in his window at a particular angle.

Ok, I can't resist. I once had a network problem that drove
me absolutely crazy. My network connection would only work
at night -- I called it the Vampire Network -- couldn't come
out in daylight.

It turned out that the morning sun (my work area faces south)
heated the in-wall cat 5 connection, and the expansion
apparently prevented good contact on all the RJ-45 pins.
It would persist all day, but an hour after sundown, bingo!
full connectivity.

After many weeks of frustration, made MUCH worse by the
fact that the link signal was active (apparently only a
data pin was affected) I finally thought of
thermal expansion, pulled the plate out of the wall,
and bent up the pins. Problem disappeared.

Good electrical contact is the stake in the heart of network
vampires! <g>

The real lesson from these stories is to be able to test
systems at many points to isolate problems. Also that
sunshine isn't good for geeks <g>.
