NetSetMan

NetSetMan exceptionally easy to use. You can create up to six different network configurations. For each, you specify the IP address, Subnet mask, default gateway, DNS server, and other information. Then, when you're at that location, with a few mouse clicks, you'll configure your laptop properly Go to another location, and with a few clicks, you're configured properly for there as well.

This program is free for non-commercial use, such as at home, at schools, and so on. But if you use it for your business, you're expected to pay for the Pro version.

Note: To run NetSetMan in Windows Vista, you'll have to run it as an administrator. To do that, right-click the program, and choose Run as Administrator.
