How to identify DELL dock uniquely?

Hi All,

I have a requirement of uniquely identifying DELL docking station when I am docking my DELL laptop. Here’s a details description of the context.

Let’s say, I have got 20 desks in my office. Each desk has got DELL dock and related peripheral devices (keyboard, mouse, display, etc;). We’ve got 20 employees who are free to use any desk. I need to make a relationship such that what laptop has connected via which docking station. I am going to write a program/script to uniquely identify each docking station when someone is docking his/her laptop and send those information to a DB. So, I am looking for some id such as serial number, MAC address (if any) or whatever which could be retrieved via a program or script?

Can anyone please give me some hits?

Cheers,

Doonyx
