How configuring IIS to use with AJAX

I'm new to AJAX. How to configure IIS to use with ASP.NET 2.0 AJAX ? Do I need to install anything to IIS so I can call it from localhost - IE....

Need explanation .........

You will need to install ASP.Net AJAX on your dev box so you can use it from localhost and also on your production server for when you deploy your solution.

I still don't understand with install 'dev box ' , what is that mean ?

I have already install ASPAJAXExtSetup.msi for extended AJAX wih my VS2005.

Do I need to install other plugin for AJAX in IIS so I can call it from localhost like dotnetframework in IIS for ASP.net ?

Can U tell me....

Have you tried the steps in this topic:

http://ajax.asp.net/docs/InstallingASPNETAJAX.aspx

It should contain the components you need for AJAX.

dev = development
box = computer or system

Yes I have already install extension for AJAX and it's work find ......

But how if the hosting server doesn't have AJAX, should I copy it myself system.web.extension.dll to my bin folder ......??

Any expert in AJAX that have problem like this ??

if your hosting provider doesn't have ajax install, then there's no way you can run ajax. placing all the DLLs in your bin requires full permission, and that is not possible for provider to grant it to you. ask the provider to install it or switch provider.
