Net Profiles

http://code.google.com/p/netprofiles/

With Net Profiles, mobile computing becomes a whole lot easier. It eliminates the need to manually reconfigure your network settings when you move your desktop/laptop computer to another location. Once a profile is created, Net Profiles can configure your IP settings, proxy settings, mapped drives, default printer, wallpaper, and screen resolution with a click of a button; as well as run any number of user-defined applications upon activation of a profile.
Net Profiles was originally coded entirely in SharpDevelop
