Event Viewer

The Windows Troubleshooting Platform records extremely detailed information in the System Event Log, both when problems occur and when network connections are successful. Additionally, administrators can use Wireless Diagnostics tracing to capture and analyze diagnostic information by using graphical tools.

You can find network diagnostic information in two places in Event Viewer:

• Windows Logs\System Look for events with a Source of Diagnostics-Networking. These events detail troubleshooting options that were presented to the user (Event ID 4000), the results of the user's choice (Event ID 5000), and detailed information gathered during the diagnosis process (Event ID 6100). When troubleshooting wireless networks, events also include the name of the wireless network adapter and whether it is a native Windows 7 driver or an older driver; a list of visible wireless networks with the signal strength, channel, and protocol (such as 802.11b or 802.11g) for each; and the list of preferred wireless networks and each network's configuration settings. Event descriptions resemble the following.
