New in the Field

Hi all,
Most of my IT experience has been relegated to what i’ve learned in the classrooms over the last 3 yrs, hardly any “real world” experience. I just transitioned over to the IT section at my job. We work in a Windows environment (2000). I’m going to be doing mostly desktop support (hardware/software), and some development work as well (Access, SQL). Any suggestions on how i can make the most of this opportunity? Thanks for your help.
