Problems Installing IIS On Windows XP SP2

Hey,
Recently I've reinstalled XPSP2 on my machine, and had hard time installing IIS on it.
After some crawling on the net, I've found this work-around:

first, make a backup for this file:

%windir%\security\database\secedit.sdb

run this on command line:

esentutl /p %windir%\security\database\secedit.sdb

click ok on the message box, then install the IIS and insert the original winxp installation cd when prompted for files.

And vuala!
