Thank you both for your help! In case anyone else has this problem, there's also another part to do.
When you take the files off of the Windows XP CD, they'll be compressed and therefore not proper .dll files or .exe files, even if you change the extension.
The way to extract them is to go to Start>Run and enter
CODE
expand C:\WINDOWS\system32\*.dll **:\
Where * is the name of the dll you need to be extracted and ** is the extraction path.
Again, thank you both for your help
