ASP.NET 4 Hosting - ASPHostPortal :: How to Resolve It is an error to use a section registered as allowDefinition='MachineToApplication' beyond application level

clock December 12, 2011 05:42 by author Jervis

You may get this error when trying to browse an asp.net application.

Server Error in '/' Application



Configuration Error

Description: An error occurred during the processing of a configuration file required to service this request. Please review the specific error details below and modify your configuration file appropriately.

Parser Error Message: 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.

Source Error:

Line 17:     <compilation debug="false" strict="false" explicit="true" targetFramework="4.0" />
Line 18:
Line 19:     <authentication mode="Forms">
Line 20:       <forms loginUrl="~/Account/Login.aspx" timeout="2880" />
Line 21:     </authentication>

It is caused by a virtual directory not being configured as an application in IIS.

However, this error occurs primarily out of 2 scenarios.

1. When you create an new web application using visual studio.net, it automatically creates the virtual directory and configures it as an application. However, if you manually create the virtual directory and it is not configured as an application, then you will not be able to browse the application and may get the above error. The debug information you get as mentioned above, is applicable to this scenario.

To resolve it, Right Click on the virtual directory - select properties and then click on "Create" next to the "Application" Label and the textbox. It will automatically create the "application" using the virtual directory's name. Now the application can be accessed.

2. When you have sub-directories in your application, you can have web.config file for the sub-directory. However, there are certain properties which cannot be set in the web.config of the sub-directory such as authentication, session state (you may see that the error message shows the line number where the
authentication or sessionstate is declared in the web.config of the sub-directory). The reason is, these settings cannot be overridden at the sub-directory level  unless the sub-directory is also configured as an application (as mentioned in the above point).

Mostly we have the practice of adding web.config in the sub-directory if we want to protect access to the sub-directory files (say, the directory is admin and we wish to protect the admin pages from unathorized users).

But actually, this can be achieved in the web.config at the application's root level itself, by specifing the location path tags and authorization, as follows:-

<location path="Admin">
<system.web>
<authorization>
<allow roles="administrators" />
<deny users="*" />
</authorization>
</system.web>
</location>

However, if you wish to have a web.config at the sub-directory level and protect the sub-directory, you can just specify the Authorization mode as follows:-

<configuration>
<system.web>
<authorization>
<allow roles="administrators" />
<deny users="*" />
</authorization>
</system.web>
</configuration>


Thus you can protect the sub-directory from unauthorized access. Good luck…

ASP.NET 4 Hosting - ASPHostPortal :: How to Encrypt Connection String in Web.Config

clock December 4, 2011 05:57 by author Jervis

The most sensitive information stored in web.config file can be the connection string. You do not want to disclose the information related to your database to all the users where the application is deployed. Every time it is not possible to have a private machine for your sites, you may need to deploy the site in shared host environment. To encrypt the connection string in above situation is advisable.

ASP.NET 2.0 provides in built functionality to encrypt few sections of web.config file. The task can be completed using Aspnet_regiis.exe. Below is the web.config file and <connectionStrings> section.   

   1: <connectionStrings>
   2:   <add name="cn1"
   3:           connectionString="Server=DB SERVER;
   4:                             database=TestDatabase;
   5:                             uid=UID;
   6:                             pwd=PWD;" />
   7:  </connectionStrings>

To encrypt the connection string section follow the steps,

1. Go to Start -> Programm Files -> Microsoft Visual Studio 2005 -> Visual Tools -> Microsoft Visual Studio 2005 Command Prompt

2. Type following command,

aspnet_regiis.exe -pef “connectionStrings” C:\Projects\DemoApplication

-pef indicates that the application is built as File System website.  The second argument is the name of configuration section needs to be encrypted. Third argument is the physical path where the web.config file is located.

If you are using IIS base web site the command will be,

 aspnet_regiis.exe -pe “connectionStrings” -app “/DemoApplication”

 -pe indicates that the application is built as IIS based site. The second argument is the name of configuration section needs to be encrypted. Third argument “-app” indicates virtual directory and last argument is the name of virtual directory where application is deployed.   

If everything goes well you will receive a message “Encrypting configuration section…Succeeded!”

Open your web.config file and you can see that connection string is encrypted,

   1: <connectionStrings configProtectionProvider="RsaProtectedConfigurationProvider">
   2:   <EncryptedData Type=http://www.w3.org/2001/04/xmlenc#Element
   3:    xmlns="http://www.w3.org/2001/04/xmlenc#">
   4:    <EncryptionMethod Algorithm="http://www.w3.org/2001/04/xmlenc#tripledes-cbc" />
   5:    <KeyInfo xmlns="http://www.w3.org/2000/09/xmldsig#">
   6:     <EncryptedKey xmlns="http://www.w3.org/2001/04/xmlenc#">
   7:
      <EncryptionMethod Algorithm="http://www.w3.org/2001/04/xmlenc#rsa
1_5"
/>

   8:      <KeyInfo xmlns="http://www.w3.org/2000/09/xmldsig#">
   9:       <KeyName>Rsa Key</KeyName>
  10:      </KeyInfo>
  11:      <CipherData>
  12:       <CipherValue>Ik+l105qm6WIIQgS9LsnF8RRxQtj2ChEwq7DbHapb440GynFEoGF6Y3EM3Iw/lyDV8+P8bIsketi5Ofy9gpZlCBir7n315Q6RPbdclUo79o/LKadhX4jHFpnSIQNIF/LhwjwkLFC0=</CipherValue>
  13:      </CipherData>
  14:     </EncryptedKey>
  15:    </KeyInfo>
  16:    <CipherData>
  17:     <CipherValue>JsLrQ5S8Pq3U72nQzmSl/XlLX72GM0O3EbPLaHRNvjTDgG9seDflGMjTfO10M1s7/mPh//3MhA7pr0dNHUJ143Svhu5YXODRC6z9CkR0uyE4H7uDvTKJ8eR3m9APhXoo1sT1K3tCLHD6a2BM+gqSk9d8PzCfbM8Gmzmpjz1ElIaxu62b4cg9SNxp8o86O9N3fBl2mq</CipherValue>
  18:    </CipherData>
  19:   </EncryptedData>
  20:  </connectionStrings>

You do not have to write any code to decrypt this connection string in your application, dotnet automatically decrypts it. So if you write following code you can see plaintext connection string.

   1: Response.Write(ConfigurationManager.ConnectionStrings["cn1"].ConnectionString);

Now to decrypt the configuration section in web.config file use following command,

For File System Application,

aspnet_regiis.exe -pdf “connectionStrings” C:\Projects\DemoApplication

For IIS based Application

aspnet_regiis.exe -pd “connectionStrings” -app “/DemoApplication” 

If you want to encrypt any nested section in web.config file like <pages> element within <system.web> you need to write full section name as shown below,

aspnet_regiis.exe -pef “system.web/Pages” C:\Projects\DemoApplication

You can encrypt all the sections of web.config file except following using the method I displayed in this article,

<processModel>
<runtime>
<mscorlib>
<startup>
<system.runtime.remoting>
<configProtectedData>
<satelliteassemblies>
<cryptographySettings>
<cryptoNameMapping>
<cryptoClasses>


To encrypt these section you needed to use Aspnet_setreg.exe tool.  For more detail about Aspnet_setreg.exe tool search Microsoft Knowledge Base article 329290, How to use the ASP.NET utility to encrypt credentials and session state connection strings.

clock December 2, 2011 05:09 by author Jervis

If you are running your application in ASP.NET 2.0 and facing the error as shown below then this is a Tip for you->

The process account used to run ASP.NET must have read access to the IIS metabase (e.g. IIS://servername/W3SVC). For information on modifying metabase permissions, please see http://support.microsoft.com/?kbid=267904.

Source Error: An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below.

Do the below to solve the above problem:

Just go to your framwork folder most probably it will be "C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\" , now this error is caused because you installed IIS after you installed ASP.NET 2.0 wo you need to register your IIS with asp.net 2.0 .


Go To command prompt and their go to C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\ and from their run "aspnet_regiis -i" this exe file will do the job for you , just restart your IIS and start your application.
