Snap-in failure?!?!?

i recently just got done following the guide here

to slip stream XP SP2 and i am quite happy with the results. my comp boots faster and seems more responsive. however, i can no longer access Group Policy Editor (gpedit.msc).

Now, i started this guide once and after about part 4 i realized i couldnt access services.msc either. So i restored my comp to before i satrted slipstreaming it and i figured out that 2 dll's which Bold Fortune said he removed in the post, are responsible for services (activeds.dll and adsldpc.dll). The error i get is:
Title - Microsoft Memory Management Console

Snap-in failed to initialize
Name: Group Policy
CLSID:{8FC0B734-A0E1-11D1-A7D3-0000F87571E3


I have a feeling it is just some dll's that are missing now, but i have no idea which ones they would be. Hopefully someone can help me. Thanx in advance.
