Troubleshooting Group Policy

Troubleshooting Networking

In Microsoft Windows Vista, Network Map diagrams the connections between devices on your network to help you troubleshoot connectivity problems. Network computers that are running Windows XP must have the Link-Layer Topology Discovery (LLTD) Responder component installed and enabled before they can appear on the Network Map or respond to the mapping computer's requests.

For more information, see Mappa rete non visualizza i computer che eseguono Windows XP.

The above topic instructs you on how to perform the following tasks:

  1. Install the LLTD Responder component onto a computer running Windows XP

  2. Verify the LLTD Responder component is installed and running

  3. Exclude File and Printer Sharing from Windows Firewall filtering

  4. Generate a new Network Map and connect to all network computers
