Web Service Extensions not found in IIS Manager

[Sam Huang]

Hi,
I newly installed VS.NET and IIS on WinXP, but when I started a new
project of ASP.NET Web Application it was stopped since ASP.NET is not
running on my IIS.

Then I opened IIS Manager and want to add a new Web Service Extension
for ASP.NET, but I cannot find Web Service Extension after expanding my
computer item.

What should I do? Have I missed something to be installed?
