If you’re having trouble getting your network set up, or if it stops working, there are some steps you can take.

First, try these steps:

Verify that your NIC is functioning	This can be done by checking Device Manager for the status of the device. (You should also go into the properties of the device.)
Do all cables have connectivity?	Are there any lights we can check on the router or back of the NIC?
Verify your Network Connections	This can be done by checking the Network Connections window. The network connection may say Enabled or Network Cable Unplugged, and may provide other important information.
Verify your IP address	This can be done by accessing your Network Connection status or using the ipconfig command in a Command Prompt window. (Keep in mind the address range of private IP addresses listed above.)

 

While network troubleshooting can by difficult at times, try to think outside the box. If a physical connection is not the problem, maybe there are some simple steps inside Windows you can check also. Here are some ideas:

• Can we run the command \\%computer name% from Start, Run box?

• Can we run the command \\%IP Address% from the Start, Run box?

• Could there be any firewalls blocking communications?

• Does the problem only occur on one computer, or all computers?

 

If you find that browsing the network through any of the above methods results in an error or just simply does not work, then repeat the steps we discussed in the lesson Preparing Your Computers for Networking. Remember, after uninstalling a feature, reboot and then re-install the feature.
