My definition is this--we have 2 in our office--the guys who do the hard wiring, wireless networking, hook up printers, scanners--or help in ones hard drive goes out, also keep our billing server and computers of the gals who do our billing functional--problem is that as more offices go electronic these guys are harder to track down --so downtime is often waiting to get one in the office quickly. Great guys to work with but they are just getting too strung out at times with all the disasters on a typical day that occur in their other clients--so probably what you are to your office Bert. Problem is I am a knucklehead when it comes to alot of these "mundane" things just to keep an office going. So it is worth it to pay these guys for their help.
