When you are connected at work, open a Run window (Windows Logo key+R), type cmd /k ipconfig /all (note the three spaces) and press Enter. Make a note of IP Address, Subnet Mask, Default Gateway and DNS Server(s), which have to be keyed in to create a static IP address. Consult your network controller if you have any difficulty.
Setting up the home dynamic connection is easy, just select Obtain IP and DNS Addresses automatically.
