LOL your story got me chuckling, and reminded me of the time I
rebooted a machine several times (along with grepping logs, removing
and loading drivers, and kicking the damn thing) trying to figure out
why it did not get a dhcp address. Got really annoyed, pulled the
machine out to install a pci ethernet card to replace the obviously
borked one on the motherboard and discovered the ethernet cable was,
errr, disconnected. It worked better when plugged in.
