I'd disagree with that (unless I am misunderstanding the definition of
active).  Every pizza box server I've seen ship in the last 3 years has had
dual onboard nics.  Dual nic setup for server (one for production and one
for administration) is best practice for any reasonable size server
environment.

than zombies, and they tend to keep the vampire population down.
