Having problems with TCP/IP (Transmission Control Protocol/Internet Protocol)?
If you can't find your normal WinIPcfg.exe file that you relied upon in Windows 98, it would be very helpful to know that in Windows 2000 the file is now called IPconfig.exe, and it isn't based on a GUI anymore. Run it from the command prompt and you'll have all of your TCP/IP network info.
Editors' note IPCONFIG is a very handy utility. For usage information, type "IPCONFIG /?" at a command prompt. This tip works on Windows 2000 Server and Professional.
