Upgrading and Installing Member Servers

Testing Network Connectivity

After you have upgraded or installed a member server, be sure to verify that you still have network connectivity. Use the list that follows as a troubleshooting guide if you lose network connectivity in a TCP/IP network environment.

Use the IPCONFIG tool to verify the TCP/IP configuration parameters on the newly upgraded Windows 2000 Server. The parameters include the IP address, subnet mask, and default gateway.
After the configuration is verified with the IPCONFIG tool, use the PING tool to test network connectivity. The PING tool is a diagnostic tool that tests TCP/IP configurations and diagnoses connection failures. Open a command prompt window and ping the following:
- Ping 127.0.0.1 (Loop back address). This will verify that TCP/IP is installed and loaded correctly.
- Ping the IP address of your local host. This will verify that it was added correctly.
- Ping the IP address of the default gateway. This will verify that the default gateway is functioning correctly.
- Ping the IP address of a remote host. This will verify that you can communicate through a router.
