For networking and IT related fields USUALLY the major you want to go into is Management Information Systems or MIS. Depending on the school the major may be slightly different. Maybe just Infomation Systems, maybe Information Technology... At my school MIS was a major in the School of Business, don't know if its that way everywhere. You can also look for a Computer Science major with a concentration in Information Technology. Don't know of any schools offhand that do the Comp Sci major with a concentration in IT.
If you don't mind the programming a general CompSci degree can usually get your foot in the door for a Networking / IT field position as well, but the classes for CompSci are usually less related to IT and more related to programming.
Dont know of any good schools for MIS offhand though, sorry!
