OK I have a small office and I was going to test Vista's new "Network
Mapping" feature that uses LLDP (Logicial Link discovery protocol).  I
haven't been able to get it to work yet.  Besides getting LLTD working
does anyone know a way to push out the LLTD Responder to XP clients
(GPO) ? Currently it is an ActiveX control install from a MS site.


I ran the LLTD responder (see first hyperlink below) on my XPSP2 pc and
rebooted - there does not appear to be a way to verify it is installed
correctly.  Nothing shows under the "local area connection" properties
to "prove" it's installed.


Per Instructions from web posts I changed the default NIC settings to
allow Netbios over TCPIP instead if DHCP. ( I will revert this back
after I get this working - I realize that this is a security


I also went in and created and applied a GPO that allows LLTD.(see 3rd
hyperlink below, this link has some good screenshots)


Link Layer Topology Discovery (LLTD) Responder (KB922120)

How to Enable the Windows Vista Network Map

work_5F00_map.aspx  Vista GPO (Can only be seen on Vista Client running
GPMC.msc) Computer Configuration -> Administrative Templates -> Network
-> Link-Layer Topology Discovery.


I haven't been able to get this to work in a domain environment, I'm
assuming it should.  Any help would be appreciated.
