I've installed visual web developer 2010 express and just typed up my first asp.net page

Each time I click on 'Debug'

I get this ERROR message:
Error      1      It is an error to use a section registered as allowDefinition='MachineToApplication' beyond application level.  This error can be caused by a virtual directory not being configured as an application in IIS.      C:\inetpub\wwwroot\Lynda ASP.Net  Exercise\Ch01GettingStarted\HelloWorld\Web.config      12      

and output message:
Validating Web Site
Building directory '/Exercise/Account/'.
C:\inetpub\wwwroot\Exercise\Ch01HelloWorld\Web.config(12): Build (web): It is an error to use a section registered as allowDefinition='MachineToApplication' beyond application level.  This error can be caused by a virtual directory not being configured as an application in IIS.

Any clues?

Set the folder "Ch01HelloWorld" in C:\inetpub\wwwroot\Exercise\ as virtual directory.

What version of IIIS you are using.

1. Confirm whether any web.config is there in any other sub folder, if so, create virutal directory for each sub folder, haing the web.config.
2. Confirm whether the website opened in visual studio is the root directory of the website having web.config file.

I would remove the part in your web.config that says "allowDefinition='MachineToApplication' ".  

I have no idea why a tutorial set would have that in there in the first place.  It's something that restricts configuration settings on higher level config files (like in a hosting environment, where the host wants to restrict clients).

I've deleted all instance of the web.config file in the directory.

I'm not sure if I'm setting up the virtual directory correctly. I just go into windows 7 IIS Manager then right click on the website folder and select 'add virtual directory'.

I'm still having the same problem.

I think, there is problem in creation of virutal directory in windows 7. Please go through the steps for creating and testing the site as mentioned in below URL:

I still have the same problem at the moment.

When i tried to create the virtual directory through IIS manager and clicked 'Test Settings...' I get an exclaimation mark next to Authorization: cannot verify access to path c:\inetpub\wwwroot\folder

The server is configured to use pass-through authentication with a built-in account to access the specified physical path. However, IIS Manager cannot verify whether the built-in account has access. Make sure that the application pool identity has Read access to the physical path. If this server is joined to a domain, and the application pool identity is NetworkService or LocalSystem, verify that <domain>\<computer_name>$ has Read access to the physical path. Then test these settings again.

I have a feeling i need to fix something else first before this problem gets fixed. So i created another question here: http://www.experts-exchange.com/Software/Server_Software/Web_Servers/Microsoft_IIS/Q_26817910.html 

It's this error:

Error Summary HTTP Error 401.3 - Unauthorized You do not have permission to view this directory or page because of the access control list (ACL) configuration or encryption settings for this resource

I think the problem here is this tutorial package is forcing you into IIS rather than just using the built in development server in visual studio.  There's a lot to learn with IIS as it is, and you're trying to do it before you've created even a simple "hello world" style web app.

I would start with the walk-throughs here:
http://msdn.microsoft.com/en-us/library/y9d53c8d.aspx

Specifically I would do this one.  It's very simple and does not use IIS.
http://msdn.microsoft.com/en-us/library/9z74w20y.aspx

I've chosen these because they are specific to version 2010.  After you get a little comfort with VS2010, I would recommend the asp.net "Ramp Up":
http://msdn.microsoft.com/en-us/rampup/dd861531.aspx

The ramp ups have video tutorials, virtual labs (which eliminate any local pc issues since you get a remote desktop), etc.  These won't be specific for vs2010, but entry level concepts of asp.net havn't changed since 2005.

From there you'll get some understanding of how things should be working and then you can move on to publishing to IIS.
