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 http://www.microsoft.com/downloads/details.aspx?displaylang=en&FamilyID=4f01a31d-ee46-481e-ba11-37f485fa34ea (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.

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