Write a small application to retrieve data from computers. -- 2

The scenario is this: 1. I need to make a list of all the computers within my local network. There are around 150 computers. 2. The data I need from the is this: a. Mac Address b. Local IP number. c. Windows version. d. Name of the PC. e. AND I need an editable field within the table to enter the name of the user myself. f. ALSO, I need a dropdown menu to select the area of that particular machine (administrative, accounting, etc.). The values of this dropdown could be a txt file that I will edit. 3. The data will be shown in a grid in a click of a button. The data will not repeat if clicked more times. The data that cannot be duplicated in data file is the mac address. 4. I need a button to export the data in grid to an xls/txt file. 5. The app will be run from a network folder. This means I will seat on every computer and run the app from that particular computer and the data will be store in that same folder. This is pretty much it. Thank you for your time.
