Which Path To Take?

Hello:

I currently have a BSEET degree from DeVry and 5 years experience as an Equipment Technician in the Semiconductor business. I want to pursue a career in IT as a Network/Systems Engineer or Administrator. I have no formal experience. ShouldI go back to school and get a BSIT, or just an MCSE Certification, or even a MSCIS? Would I be wasting valuable time getting another BS degree when I already have one? Would an MS degree overqualify me? Every non IT person has a different opinion. Ihave been racking my brains. Can someone please set me straight on which path to take? I would really appreciate it.

Thank you,

HK
