This is pretty funny:

The University of North Carolina has finally found a network server that, although missing for four years, hasn’t missed a packet in all that time. Try as they might, university administrators couldn’t find the server. Working with Novell Inc. (stock: NOVL), IT workers tracked it down by meticulously following cable until they literally ran into a wall. The server had been mistakenly sealed behind drywall by maintenance workers.

Thanks to Vince on the ASAE tech list for the link and the Poe reference.
