Installing the Link Layer Topology Discovery (LLTD) Responder on Windows Server 2003

Under Windows Vista and higher it is possible to view a graphical map of your network by clicking “View Full Map” in the Network and Sharing Center or by using the command “explorer.exe ::{21ec2020-3aea-1069-a2dd-08002b30309d}\::{E7DE9B1A-7533-4556-9484-B26FB486475E}”. To build the network map, Windows queries each system on the network using the Link Layer Topology Discovery (LLTD) protocol.

The LLTD protocol was introduced in Vista. Unfortunately, older versions of Windows (like XP and Server 2003) that don’t have the LLTD protocol installed will not respond to network map requests, and will not show up at all on the network map display. Microsoft has provided the Link Layer Topology Discovery (LLTD) Responder (KB922120) update package which can be installed on Windows XP systems to have them show up properly under the network map. Microsoft did not release a version of the LLTD responder for Windows Server 2003. The XP release of the LLTD Responder will work fine on Windows Server 2003, but you have to install it manually.

First you will need to download the “Link Layer Topology Discovery (LLTD) Responder (KB922120)” update package for Windows XP (WindowsXP-KB922120-v5-x86-ENU.exe).

Extract the contents of the installer package using the –x switch (WindowsXP-KB922120-v5-x86-ENU.exe -x). It will ask you for a location and extract it’s contents there.

Inside the directory where the package was extracted there will be a “SP2QFE” subdirectory which contains the files we need to copy:

  1. Copy the “rspndr.exe” file from the SP2QFE subdirectory into the “%SystemRoot%\system32” directory.
  2. Copy the “rspndr.sys” file from the “SP2QFE” subdirectory to the “%SystemRoot%\system32\drivers” directory.
  3. Copy the “rspndr.adm” and “rspndr.inf” files inside the “SP2QFE\IP” subdirectory into the “%SystemRoot%\INF” directory.

After the files are copied, run the command “rspndr –i” to install the driver’s entries in the system registry and start it (net start rspndr).

There should now be a new protocol entry for “Link-Layer Topology Discovery Responder” under your network adapter’s properties, and your Windows Server machine should show up on the network map.
