Server Error 404 - File or directory not found. The resource you are looking for might have been removed, had its name changed or is temporarily unavailable.

I have built a project and deployed on server, when try to open a page which is using asp.net routing I get this error message “Server Error 404 - File or directory not found. The resource you are looking for might have been removed, had its name changed or is temporarily unavailable.”

There are three steps you have to follow:
1. You need to install HTTP Redirection in World Wide Web Services.

2. Change Web.Config System.WebServer keys:

<system.webServer>
<modules runAllManagedModulesForAllRequests="true">
<remove name="UrlRoutingModule"/>
<add name="UrlRoutingModule" type="System.Web.Routing.UrlRoutingModule, System.Web, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
</modules>

<handlers>
<add name="UrlRoutingHandler" preCondition="integratedMode" verb="*" path="UrlRouting.axd" type="System.Web.HttpForbiddenHandler, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"/>
</handlers>
</system.webServer>

3. Generate Your Routes:

RouteTable.Routes.Add( new ServiceRoute("Northwnd", new DataServiceHostFactory(), typeof(Northwnd)))
