Symptoms
Consider the following scenario:
-
You install a Network Driver Interface Specification (NDIS) driver on a computer that is running Windows 8 or Windows Server 2012.
-
The physical network adapter on the computer is disabled. Therefore, the loopback address is the only address available for communication.
-
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.
In this scenario, the application cannot connect to the IP address.
