Sorry LR that post was meant to be tongue in cheek.
Crack on fiddling.
To be honest I have not got a single qualification in IT or networking.
I learn't by fiddling, breaking things, fixing them again. Then I discovered people were willing to pay me for fiddling with things, in fact big things, things that used lumps of metal in space to talk to each other. Payed you silly amounts of money to do it as well.
Now I am a pilot, still fiddling with IT networks when things go wrong.
Actually I quite like this forum because there are some good "think outside the box" problems crop up. Its taken me back ten years to the stuff I used enjoy about IT. You could do it all the time as a contractor but the life of a permy IT admin didn't look a very pleasant one.
