I've mostly found it a sign of a company's size/age/maturity as to how boring the server names are. Several places I've worked for started out with the admins coming up with their funny/cute/dorky naming schemes, only to eventually have server names be locked down in the name of STANDARDIZATION.
Then you have endless meetings to decide what should be the important components of a system name. Should it indicate the machine's location? It's OS? It's function? Should it even indicate which rack number and elevation slot the system is in? Eventually you end up with racks full of servers named SJC-LX-APPDEV01, NYC-SV-EXCHG02, and LDN-UX-SMTPDR01.
I have to admit, a little part of me misses having room for a little creativity in naming systems, but then the rest of me doesn't miss wasting time trying to come up with names for work systems. I've always got my home network to label with my ever-changing nerdly obsessions.
