From the TechNet Library: Network Map Does Not Display Computers Running Windows XP.
Network Mapping disabled on a domain.
XP needs to have the Link-Layer Topology Discovery (LLTD) protocol installed and enabled in order for the Windows Vista Network Map feature to capture an XP machine's presence.
The download: Link Layer Topology Discovery (LLTD) Responder (KB922120).
Note that the download is for XP SP2 automatic install only with the following instructions on how to get it into XP SP3:
- From any Explorer window (not IE) click on "Tools" -> "Folder Options" -> "View" tab.
- Enable the radio button labeled "Show hidden files and folders" and uncheck the "Hide extensions for known file types".
- Download the installer file from here (if you don't already have it)
- Rename it to something like LLTD.exe (unless you really want to type out "WindowsXP-KB922120-v5-x86-ENU.exe") and put it in the root of your
- Go to Start -> Run, and type in "cmd" (without the quotes) and hit Enter.
- When the black command prompt comes up, type in "cd c:\" (minus
quotes) and hit Enter.
- Now type in "LLTD.exe -x:c:\LLTD" (again, minus quotes). This will extract all the files in to a new folder called c:\LLTD.
- Open that folder with an Explorer window, and there will be another folder inside it called "SP2QFE". Open that, find the file named "rspndr.sys", and copy it inside your c:\Windows\system32\drivers directory.
- Also in the "SP2QFE" folder, find the "rspndr.exe" and copy it inside your c:\Windows\System32 directory.
- Finally in the IP Folder, find the "rspndr.inf" file , and copy it inside your c:\Windows\inf directory.
- Now back in the command prompt enter "cd C:\Windows\system32" and then enter "rspndr.exe -i". This will actually install the LLTD.
- When it completes, you should get a notice stating that it's installed.
- Go to your Network Interface Card and verify that you see Link Layer Topology Discovery.
Thanks for that Jon!
