Windows 7 - LLTD on/off ?

Trying to disable as much as possible when It's from MS, but I wan't
to make sure that it's a benefit instead of the opposite..

So,, In a Novell/Netware, Zen10 network,
the Link Layer Topology discover responder and mapper,
are they of "benefit" only in an MS enviroment or should they be
enabled when these PC's are to be managed trough Zen10 ??

Anyone with thoughts about this ?
