Checking IP configuration to troubleshoot Windows network connectivity

Learn how to check network IP configuration for a computer running Windows Server 2003, in this tip. You can diagnose network connectivity problems by performing these simple command line (CL) ping tests -- if you are having trouble communicating with hosts on the network, or hosts on remote networks.

In the first article in this series, Using ping command to begin troubleshooting Windows network connectivity, I started out by showing you how to use the ping command to perform some basic connectivity tests, and then talked about how you can interpret the results. In this article, I want to continue the discussion by showing you some more simple tests that you can use to diagnose the current state of connectivity.

Introductory note
As I explained in the first part of this article series, my goal is to create a troubleshooting guide that anyone with basic skills can follow. That being the case, I am starting with basic troubleshooting techniques, and as the series progresses, I will gradually move into more advanced techniques.

Confirming connectivity
In the previous article, I showed you the basics of using the ping command to test network connectivity. However, if you are having trouble communicating with other hosts on the network, or hosts on remote networks, then there are a few more ping tests that you can perform in order to get a better idea of what's going on.

Before I show you those techniques though, it is important to understand how the host that is having communications problems is configured. The procedure for doing so varies from one version of Windows to the next, so I will show you how to check the network configuration  on a machine that's running Windows Server 2003.

The first thing that you must do is to determine whether the machine in question is running a static or a dynamic IP address configuration. To do so, open the Control Panel, and choose the Network Connections option. Now, right click on the connection that you are trying to diagnose, and choose the Properties command from the resulting shortcut menu. Upon doing so, you will see the connection's properties sheet, as shown in Figure A.

Now, scroll through the list of items that the connection uses until you locate...
