I had this same problem and am still trying to get Microsoft support to
determine why it does not seem to be in SP3 like they say.
However, I found two ways to deal with it.
1. If you install the LLTD before you install SP3, it works fine.
2. After SP3 or when you do a fresh install of XP SP3, even though the
protocol won't self install you can install it youself by first
Download the LLTD hotfix KB922120
and extract the required files.
Here's how to do it.
In the folder where you extract to you will find a folder SP2QFE.
Open this and you will find the required files.
Then copy the rspndr.sys to C:\Windows\System32\Drivers folder,
rspndr.exe to C:\Windows\System32 folder.
rspndr.inf (inside ip folder) to C:\Windows\Inf folder
Then open a Command prompt as administrator and navigate to the
C:\Windows\System32 folder and type rspndr.exe -i
This will install the LLTD responder.
