I want run Internet Information Server.I installed everything.My OS is windows xp prof sp2.But after installation i am not able to find web service extensions.What should i do for this?.

Web Service Extensions is a feature introduced with IIS6.

IIS6 shipped on:
- Windows Server 2003 32bit
- Windows Server 2003 64bit
- Windows XP Pro 64bit

It does not exist for IIS 5.1 on Windows XP Pro 32bit.

If you have .net installed, you can start asp.net by running the command: aspnet_regiis -enable

where to run this command? in dos window or run window from start? i tried both,but not working.Whether IIS will work on windows xp?...can u telll briefly what IIS is doing realy?

What is meant by service extensions which is present on IIS6?...actually i am getting through this when i want install a specific s/w which has got IIS installation as a prerequirement..
