How to Ping the loopback address to verify that TCP/IP is installed and correctly configured on the local computer?

Ping the loopback address to verify that TCP/IP is installed and correctly configured on the local computer. To do this, type the following command: ping 127.0.0.1 If the loopback test fails, the IP stack is not responding. This problem may occur if any one or more of the following conditions is true: The TCP drivers are corrupted. The network adapter is not working. Another service is interfering with IP. Ping the IP address of the local computer to verify that the computer was correctly added to the network. If the routing table is correct, this procedure just forwards the packet to the loopback address of 127.0.0.1. To do this, type the following command: ping  IP address of local host If the loopback test succeeds but you cannot ping the local IP address, there may be an issue with the routing table or with the network adapter driver. Ping the IP address of the default gateway to verify that the default gateway is working and that you can communicate with a local host
