Problems NetTool Detects

You can think of problems fitting into one of two categories: link connectivity or network. Link connectivity problems relate to cabling or cabling properties while network problems involve PC/network configuration settings or PC-to-server interactions.

Generally, you encounter network problems while setting up or changing a PC’s connection to the network. These types of problems can often be resolved by checking the network settings on the PC.

With a single-ended connection, NetTool can only report Unwanted Protocols and link connectivity level problems. An inline connection is required for all other problems. The different types of connections are discussed in Chapter 2.

NetTool enables you to see on which side the problem exists; that is, whether it is a problem between the PC and NetTool or whether it is between NetTool and the network itself. Whether it is a cabling problem or a protocol mismatch, NetTool helps you isolate a problem and keep things running.

This section lists by category the problems that NetTool can detect. For each problem, an explanation (if needed) is given and possible corrective steps are provided.

Every network is complex and the solutions given are meant to assist you with troubleshooting. This is not an exhaustive troubleshooting guide.

Link Connectivity Problems

The problems listed in this section involve cabling or cabling properties.

Problem: Speed mismatch

Explanation: The network is running at 10 Mbps and the PC is running at 100 Mbps (or vice versa). This speed mismatch prevents connection to the network.

Remedy: Correct the speed mismatch by making sure both devices are running at the same speed.
