My Windows Server 2003 and Windows XP machines are shown as computers that can't be placed in the Windows Vista network map.

A. By default, XP machines don't have a Link Layer Topology Discovery (LLTD) responder to allow the XP machine to be placed in the network map. For XP Service Pack 2 (SP2) machines, a LLTD responder is available from (KB 922120). The responder will allow XP machines to show in the network diagram as known devices. The savdalwks01 in the figure is an XP machine with the LLTD responder installed.

Corrections to this Article:

  • There currently isn't an LLTP responder for any other OS, such as Windows 2003.
