Question

I had an ASP.net project and I’ve copied and pasted the source files to another computer, but when I try and run them on this computers localhost:

    Error Summary
HTTP Error 500.19 - Internal Server Error
The requested page cannot be accessed because the related configuration data for the page is invalid.
Detailed Error Information
Module  IIS Web Core
Notification    BeginRequest
Handler Not yet determined
Error Code  0x80070021
Config Error    This configuration section cannot be used at this path. This happens when the section is locked at a parent level. Locking is either by default (overrideModeDefault="Deny"), or set explicitly by a location tag with overrideMode="Deny" or the legacy allowOverride="false".
Config File \\?\C:\inetpub\wwwroot\myproj\myproj\web.config
Requested URL   http://localhost:80/myproj/myproj/default.aspx
Physical Path   C:\inetpub\wwwroot\myproj\myproj\default.aspx
Logon Method    Not yet determined
Logon User  Not yet determined
Config Source
   96:      </modules>
   97:      <handlers>
   98:          <remove name="WebServiceHandlerFactory-Integrated"/>

I’m moving it from IIS6 to IIS7 if that helps at all.

Answer 1

It looks like you haven’t used the IIS Management tool to make the folder into an Application / Virtual Directory. There’s step-by-step instructions on Technet, and an overview of Sites, Applications and Virtual Directories on iis.net.

The part of the message:

This configuration section cannot be
used at this path. This happens when
the section is locked at a parent
level. Locking is either by default
(overrideModeDefault=”Deny”), or set
explicitly by a location tag with
overrideMode=”Deny” or the legacy
allowOverride=”false”.

Does seem to indicate that the folder isn’t setup as a virtual directory / application as the <handlers> section should be changeable.
