I've created a base image of Windows XP which has Zenworks and the Novell client pre-installed. I've also created a large add-on image containing all of the applications required for our base build. Once these images are restored I can login as workstation only or as a network user and these applications work perfectly.

The problem is that we want to send a DVD out to users that automatically adds new applications to the nalcache, but after restoring these images and logging in the new applications disappear from the nalcache. I have managed to prove that the files are correctly restored to the nalcache but when NAL loads it clears them out!

I've seen dozens of posts on this but no real answer on what is happening.
Can anyone explain why this is?
