HTTP 오류 500.22

c VS2005 에서 만들어진 프로젝트를 Windows 2008 Server(IIS 7.0)에 적용하면 아래와 같은 에러가 발생한다.

HTTP 오류 500.22 - Internal Server Error
관리되는 통합 파이프라인 모드에 적용되지 않는 ASP.NET 설정이 있습니다.

이건 또 머야... 싶은데..
IIS7.0에 셋팅 시 Web.Config를 수정해줘야 한다..

1. authenticationService section 삭제

<configuration>
    <configSections>
        <sectionGroup>
             <section name="authenticationService" type="System.Web.Configuration.ScriptingAuthenticationServiceSection, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" requirePermission="false" allowDefinition="MachineToApplication" />
~~~

2. System.Webserver section 추가

 <!--
        IIS(Internet Information Services) 7.0에서 ASP.NET AJAX를 실행하려면
        system.webServer 섹션이 필요합니다. 이전 버전의 IIS에서는 필요하지 않습니다.
    -->
  <system.webServer>   
    <validation validateIntegratedModeConfiguration="false"/>
    <modules>
      <remove name="ScriptModule" />
      <add name="ScriptModule" preCondition="managedHandler" type="System.Web.Handlers.ScriptModule, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
    </modules>
    <handlers>
      <remove name="WebServiceHandlerFactory-Integrated"/>
      <remove name="ScriptHandlerFactory" />
      <remove name="ScriptHandlerFactoryAppServices" />
      <remove name="ScriptResource" />
      <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>
