- An application initiates a connection to an IP address, and the TCP/IP Path is created by using the loopback address.
- The IP address is added to the loopback interface. Then, you enable the physical network adapter and allow the network adapter to communicate with the IP address.
- The TCP/IP driver selects an incorrect TCP/IP path that has the loopback address as its source address.
