How to install IIS on Windows XP SP3 without installation CD

I have the installation discs, but they are somewhere at home and it'll probably take me long time to find them.
After searching in the web, this is the method that I use to install IIS on Win XP SP3:

1. Download Windows XP SP3 patch from The Software Patch
2. Open the downloaded exe file using winRAR and extract the files to a local folder (folderX)
3. Download the IIS 5.1 required files from AP Dubey tech corner and extract the files to a local folder (folderY)  [I guess I could've used all files from this site, but since this site is for Win XP SP2, I've decided to use SP3 patch files if the file exists in SP3 patch.]
4. Go to Control Panel from Start menu in your computer 
5. Double click Add or Remove Programs
6. Select Add/Remove Windows Components on the left
7. In the Windows Components wizard window, put a check mark beside IIS and click Next.
8. When prompt for "staxmem.dl_" file, use the browse button to find it in [folderX]\i386\staxmem.dl_
9. When prompt for "adsutil.vbs" file, use the browse button to find it in [folderX]\i386\ip\adsutil.vb_
10. When prompt for other files, you'll find them in

After installation is completed, you can open IIS by:

1. Go to Control Panel from Start menu
2. Double click Administrative Tools
3. Double click Internet Information Services

The default web publishing directory for IIS is:
C:\Inetpub\wwwroot

Copy your personal web pages to this folder.

IIS will search for the default page in the following sequence by default:
Default.htm
Default.asp
index.htm
iisstart.asp
You can change the name and sequence of default document.

If all setup is completed, you should see your site using following URL in your browser.
http://localhost/
