I don't get this error when I run my default.aspx page using the built in VS web server (VS 2008)
I do get this error when I load my localhost\default.aspx in my .NET 3.5 Web application on my Vista Ultimate Box using IIS (not the built in VS web server):
HTTP Error 500.19 - Internal Server Error
Description: The requested page cannot be accessed because the related configuration data for the page is invalid.
Error Code: 0x80070021
Notification: BeginRequest
Module: IIS Web Core
Requested URL: http://localhost:80/
Physical Path: C:\www\Projects\3.5 VS 2008 Beta\Elbalazo\Web
Logon User: Not yet determined
Logon Method: Not yet determined
Handler: Not yet determined
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:\www\Projects\3.5 VS 2008 Beta\Elbalazo\Web\web.config
This error occurs when there is a problem reading the configuration file for the Web server or Web application. In some cases, the event logs may contain more information about what caused this error.
Server Version Information: Internet Information Services 7.0.
The handlers section is talking about this in my web.config which I believe is there by default when you create a new web application in the .NET 3.5 framework:
<!--
The system.webServer section is required for running ASP.NET AJAX under Internet
Information Services 7.0. It is not necessary for previous version of IIS.
-->
<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>
<defaultDocument>
<files>
<clear />
<add value="default.aspx" />
<add value="index.aspx" />
</files>
</defaultDocument>
</system.webServer>
Initially I thought this problem was because I needed to change overrideModeDefault="Deny" to overrideModeDefault="Allow" so I changed all instances of this to Allow in my C:\Windows\System32\inetsrv\config\applicationHost.xml
file on my Vista Ultimate machine. That made this error go away but then the second error stated that a handler that is mapped in my web.config has a problem.
I then get this second error:
HTTP Error 404.3 - Not Found
Description: The page you are requesting cannot be served because of the Multipurpose Internet Mail Extensions (MIME) map policy that is configured on the Web server. The page you requested has a file name extension that
is not recognized, and is not allowed.
Error Code: 0x80070032
Notification: ExecuteRequestHandler
Module: StaticFileModule
Requested URL: http://localhost/Default.aspx
Physical Path: C:\www\Projects\3.5 VS 2008 Beta\Elbalazo\Web\Default.aspx
Logon User: Anonymous
Logon Method: Anonymous
Handler: StaticFile
Most likely causes:
It is possible that a handler mapping is missing. By default, the static file handler processes all content.
The feature you are trying to use may not be installed.
The appropriate MIME map is not enabled for the Web site or application. (Warning: Do not create a MIME map for content that users should not download, such as .ASPX pages or .config files.)
What you can try:
In system.webServer/handlers:
Ensure that the expected handler for the current page is mapped.
Pay careful attention to preconditions (e.g. runtimeVersion, pipelineMode, bitness) and compare them to the settings for your application pool.
Pay careful attention to typographical errors in the expected handler line.
Please verify that the feature you are trying to use is installed.
Verify that the MIME map is enabled or add the MIME map for the Web site using the command-line tool appcmd.exe.
Open a command prompt and change directory to %windir%\system32\inetsrv.
To set a MIME type, use the following syntax: appcmd set config /section:staticContent /+[fileExtension='string',mimeType='string']
The variable fileExtension string is the file name extension and the variable mimeType string is the file type description.
For example, to add a MIME map for a file which has the extension ".xyz", type the following at the command prompt, and then press Enter:
appcmd set config /section:staticContent /+[fileExtension='.xyz',mimeType='text/plain']
Warning: Ensure that this MIME mapping is needed for your Web server before adding it to the list. Configuration files such as .CONFIG or dynamic scripting pages such as .ASP or .ASPX, should not be downloaded directly and should always be processed through
a handler. Other files such as database files or those used to store configuration, like .XML or .MDF, are sometimes used to store configuration information. Determine if clients can download these file types before enabling them.
Create a tracing rule to track failed requests for this HTTP status code. For more information about creating a tracing rule for failed requests, click
here.
This error occurs when the file extension of the requested URL is for a MIME type that is not configured on the server. You can add a MIME type for the file extension for files that
are not dynamic scripting pages, database, or configuration files. Process those file types using a handler. You should not allows direct downloads of dynamic scripting pages, database or configuration files.
Server Version Information: Internet Information Services 7.0.
I have still no clue how to resolve this after trying to look at the web.config and IIS.
I stated in my initial post that I did that...Please re-read...thanks.
Also I confirmed that this happens to any web project I create in VS 2008. I tried just a simple test project and tried to run http://localhost/, same error message in it's out of box default.aspx page for this test project.
Received this same issue after installing IIS 7 on Vista Home Premium. To correct error I changed the following values located in the applicationHost.config file located in Windows\system32\inetsrv.
Change all of the following values located in section <configSections> --> <sectionGroup name="system.webServer">
<div mce_keep="true"><section name="handlers" overrideModeDefault="Deny" />
change this value from "Deny" to "Allow"</div>
<div mce_keep="true"><section name="modules" allowDefinition="MachineToApplication" overrideModeDefault="Deny" />
change this value from "Deny" to "Allow"</div>
I did exactly what is written here,but I still have the second Error "The page you are requesting cannot be served because of the extension configuration. If the page is a script, add a handler. If the file should be downloaded, add a MIME map."

Is there anybody,who knows how to fix it???
Thanks.
