LLTD Responder (protocol) and XP Pro x64

November 2, 2007

Hi folks,

I've just bought a new laptop with Vista Home Premium. Seems everything

works fine on it. I have a home network. It's a "hybrid", DLink DI-524

WirelessG router and 4 port switch. Desktop is wired to the router,

external hd wired to router. Desktop is running XP Pro x64. Also have an

old laptop running XP Home.

The only networking problem I have (I think) is that my Vista system won't

see either of the XP systems in the Network Map or in Explorer - Network if

it is turned on while the other systems are already running. I literally

have to turn on the Vista laptop first, then start or reboot the XP systems.

Network Discovery Help tells me that I need to install "Link Layer Topology

Discovery Responder" on the two XP systems. I found that for XP x86. I

haven't found that for XP Pro x64. Apparently it is not included in the x64

SP2, which I just installed on the x64 machine.

*WHEN* the Vista machine does see the other two systems, they can all 3 talk

back and forth, file and printer sharing, all day long, just fine.

Any help for this one?

TIA!

McG.
