I am currently going to University of Phoenix for IT. When done I will have a BSIT with a Database Administration emphasis. There are a lot of people working on Networking related emphasis degrees.
Networking is definitely a field that is still growing and you can make some decent money. I would recommend checking local community colleges first for a school. It will be less expensive and you can be pretty sure the credits will transfer if you want or need to change schools later.
Some good information in this thread also:
