Network Map Does Not Display Your Windows XP-based Computers

Applies To: Windows Server 2008

In 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 about the procedure to install the LLTD Responder component on a computer running Windows XP, see "Network Map Does Not Display Computers Running Windows XP" (

This topic describes 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.
