You upgrade your network to 1000 Mbps from 100 Mbps. You install a new 1000-Mbps network adapter into your Windows system. You check the device manager and see no errors or warning. You configure the TCP/IP settings to be as they were for the previous network adapter. Upon restarting the computer, you cannot access the network. You ping your IP address locally and receive the error message, "Request timed out." You then ping 127.0.0.1 and receive the same error message. What do you do?

Replace the NIC

Explanation:

A node needs a network connectivity to perform and function well as part of a cluster. If a single network interface is available, the breakdown of the other network interfaces will not cause service interruption but will most likely cause service degradation.

Simple ways to know if you need to change your NIC is to go Click Start and the you right-click on Computer, then you toggle over and click Properties, it will bring a window box and From there, click Device manager. Screen the window to where it says "Network adapters". If there's a question mark or an exclamation there, then you have an ethernet problem that needs troubleshooting; if not then you're OK.
