And just to add to the bishop's comments. When I first started working with the bishop, I asked him what qualifications he had in Networking. His answer was "experience". Unless things have changed and he hasn't told me, the bishop doesn't have any official qualifications to do with networking. All his experience has been gained in the real world! But, he has very good theoretical knowledge as well, gained from reading, testing etc.
So, alot of the experience I have gained, as been learned by him giving me a challenge, letting me work on it. And, being available if I definately can't get anywhere. He points me in the right direction, and let me "sink or swim". It has to be said of course, that this is not on the live network, but our test network.
