Well if your only vision of IT professionals is from a SNL skit then you need to wake up.
Besides, Nick Burns' job isn't exactly in Networking, its in "being everyone's b****". Networking IT professionals spend more time configuring networks, installing servers, providing connectivity to users, and other things. There should be a seperate person in the IT department who handles helpdesk issues (fixing computers, trouble shooting user problems, explaining to users that they should drop their laptops, etc...).
I suppose if you work for a small company or a public school you'll end up wearing multiple hats but if you truely want to work in Networking, an A+ certificate is the wrong direction. As people have mentioned, Cisco certifications, SUN certifications, and courses in Networking (TCP/IP, routing, load balancing, unix administration) instead of Windows desktop troubleshooting will get you in the right direction.
For starters, install Linux on your machine (if you haven't already) or a spare machine and try to get things working on it. Start with Apache, FTP, and Samba then move on to more complex things like configuring a DHCP server, a firewall, make samba your Windows Primary Domain Controller (PDC) and so forth. Become familiar with unix. Then pick up an old Sun sparc machine and do the same with Solaris. (You can get a SparcStation and a copy of Solaris 7 or 8 on ebay cheap).
