Windows 7 / Networking

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.
    The Network Diagnostics Framework has completed the repair phase of operation.
    The following repair option or work-around was executed:
    Helper Class Name: AddressAcquisition
    Repair option: Reset the network adapter "Local Area Connection"
    Resetting the adapter can sometimes resolve an intermittent problem.
    RepairGuid: {07D37F7B-FA5E-4443-BDA7-AB107B29AFB9}
    The repair option appears to have successfully fixed the diagnosed problem.
  • Applications and Services Logs\Microsoft\Windows\Diagnostics-Networking \Operational This event log details the inner workings of the Windows Troubleshooting Platform and will be useful primarily when escalating problems to Microsoft support.
