XP SP3 Slipstream problems

[Raboo]

I'm trying to slipstream SP3 to a previously nlited XP with SP2 slipstreamed.

1. People are mentioning RTM, what is that?

2. When slipstreaming SP3 in nlite, it asks if I should remove previous service packs, Yes or No?

3. I selected NO and it slipstreamed fine, but when installing XP it gets a lot of error messages of files missing during the copy of files phase, ex. drwatson.exe which i previously stripped of when i had SP2 on my nlite'ed XP.

How do I solve these issues without starting from a clean XP?

You start from a fresh install/source, end of story.
