This is the kind of stuff I deal with on a daily basis, and it's not an isolated thing. Too often a company will hire a tech without knowing what the tech can and cannot do. Too often that "tech" is a FOAF (friend of a friend) who "knows some stuff about computers", when in all actuality they were just barely able to set up their own DSL modem and get their shiny new smartphone to talk to if over WiFi. These are the kind of guys who can barely install a printer on a workstation, much less share it out and make sure it works properly for other computers on the network in a workgroup configuration. Then, finally, when they make a dog's lunch out of the setup of everything, they blame the issues the software is exhibiting on the software, instead of the underlying network or computer configurations, and play dumb when we call them on the carpet.
These are the situations that make me cry for a proper licensing for computer technicians. I'm not talking about specialized certifications, like those provided by Cisco and other providers. I'm talking about a general, standardized technology certification that confers a license to service, repair, and otherwise handle computer and network hardware. CompTIA's certs are the closest thing I've seen to a general certification, with the A+ and Network+ exams, but even then there is no requirement for someone to pass these to be able to call themselves a "computer tech". Automotive techs have to pass ASE certification to prove their competence. Lawyers have to pass the bar exams. Medical practitioners have to pass their own licensing exams. Yet, for some reason, there is no blanket certification authority for computer techs, and it just makes me shake my head.
