well networking is a no brainer, and well i am doing a network course here, and i have completed coruses in:
DOS, UNIX, WIN2K Server, Exchange server 2000, Novell Netware 5.5, Cisco intertenworking, Microsoft Office, and Advancded Microsoft Office, Hardware Fundamentals, Hardware Troubleshooting, Networking Fundamentals, Network design and analysis
and in my last semester i am going to be doing SMS Server, Microsoft Client, Current Trends, Periphiriles, Security, and some other person al development courses.
I love the course, it is awesome, though the last semester was hard ass and dropped my GPA to a 3.64
Bu i got one more semester to get it back up.
id say look into some sort of cisco academy course, as well as anything along the lines of my course, i am doing a course called Computer Support Specialist.
hope that helps
