You are trying to jump start an existing ASP.NET site on a new IIS 7.5 server under Windows 7/7.5 or under Windows 2008 R2, and you are getting this error message: The problem is in IIS 7.5 DefaultAppPool settings.

Windows 2008 Server with IIS 7.0/7.5 runs DefaultAppPool using Network Service user:

Windows 7.0/7.5 and Windows 2008 Server R2 with IIS 7.5 run the same pool under a different user – ApplicationPoolIdentity:

All you need to do is to change that setting on your machine.

Use IIS Admin – Application Pools.
1- Right mouse click on DefaultAppPool row,
2- Select Advanced Settings,
3- A first setting under Process Model group is Identity,
4- Select it and using a drop down list change Built-in account from ApplicationPoolIdentity to NetworkService.

Now check your application log in, it will work

Hope this will work

<httpRuntime useFullyQualifiedRedirectUrl="true|false"
             maxRequestLength="size in kbytes"

Example

The following example specifies HTTP runtime parameters for an ASP.NET application.

<configuration>
   <system.web>
      <httpRuntime maxRequestLength="4000"
         useFullyQualifiedRedirectUrl="true"
         executionTimeout="45"
         versionHeader="1.1.4128"/>
   </system.web>
