IPTool was designed to be an all around Network configuration troubleshooting tool. It supports multiple network adapters, and allows the user to perform the following additional functions:

1. Release the current IP
2. Renew the current IP lease
3. Change the device name of the PocketPC device

 It also displays all available Network information, including wep key state information (it does not crack wep keys).

I used a portion of Open NetCompactFramework. You do not need to have this installed, the application comes with the related dll files. You do need .NET Compact Framework, however.
