Ohio Forensic Guide

I have 20+ years experience in the office, but as an office manager and administrative associate. I want to go into IT now, and have an Associate’s in Business. What classes or certifications should I look into that would get me into the IT department sooner?
I receive educational reimbursement for up to 4 classes a year, so this is definitely a 2-5 year deal. I would like to go into some kind of computer forensics, and can readily advance where I work if I do that.
Let me know the basic training that all employers look for, and any specialized training that can put me into a good candidate position for hire.
Thanks!
