TCP/IP Troubleshooting Tools and Strategies
Windows 2000 includes several utilities with the TCP/IP stack. Many of these have enhanced functions as well.
IPConfig
IPConfig is a command-line utility that prints the TCP/IP configuration of a host. When used with the /all switch, it produces a detailed configuration report for all interfaces, including any configured serial ports (RAS). You can also redirected output to a file.
Caching DNS entries speeds up name resolution, but you might not see changes made to DNS entries. Rebooting the server fixes this; however, ipconfig has some new options that solve this problem without rebooting. New options available include
| ipconfig /displaydns | Displays a list of DNS entries Windows has cached |
| ipconfig /registerdns ... |
