If you are adding <system.webServer> tag inside <configuration> like following then you could avoid step 2 and 3

 

<system.webServer> <validation validateIntegratedModeConfiguration="false" />      <modules> <add name="ScriptModule" preCondition="integratedMode" type="System.Web.Handlers.ScriptModule, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" /> </modules>      <handlers> <remove name="WebServiceHandlerFactory-Integrated" />        <add name="ScriptHandlerFactory" verb="*" path="*.asmx" preCondition="integratedMode" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0,Culture=neutral,PublicKeyToken=31bf3856ad364e35" />        <add name="ScriptHandlerFactoryAppServices" verb="*" path="*_AppService.axd"   preCondition="integratedMode" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral,PublicKeyToken=31bf3856ad364e35" />        <add name="ScriptResource" preCondition="integratedMode" verb="GET,HEAD" path="ScriptResource.axd" type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=3.5.0.0, Culture=neutral,PublicKeyToken=31bf3856ad364e35" />      </handlers>   </system.webServer>
