Webconfig error.

I thought it might be a database error. Now I think it is a web.config.
Server Error in '/Cms' Application.

Cannot open database "CMS" requested by the login. The login failed.
Login failed for user 'NT AUTHORITY\NETWORK SERVICE'.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.Data.SqlClient.SqlException: Cannot open database "CMS" requested by the login. The login failed.
Login failed for user 'NT AUTHORITY\NETWORK SERVICE'.

<?xml version="1.0"?>


    Note: As an alternative to hand editing this file you can use the 

    web admin tool to configure settings for your application. Use

    the Website->Asp.Net Configuration option in Visual Studio.

    A full list of settings and comments can be found in 

    machine.config.comments usually located in 



<configuration xmlns="">


    <add key="FCKeditor:UserFilesPath" value="/Cms/UserFiles"/>



     <add name="Cms" connectionString="Data Source=Quincy;Initial Catalog=CMS;Integrated Security=True;" providerName="System.Data.SqlClient" />




      Set compilation debug="true" to insert debugging 

      symbols into the compiled page. Because this 

      affects performance, set this value to true only 

      during development.

      Visual Basic options:

      Set strict="true" to disallow all data type conversions 

      where data loss can occur. 

      Set explicit="true" to force declaration of all variables.


    <compilation debug="true" strict="false" explicit="true" />

    <roleManager defaultProvider="SqlProvider"








        cookieProtection="All" >





          connectionStringName="Cms" />



    <membership defaultProvider="SqlProvider">


        <add name="SqlProvider"

            type="System.Web.Security.SqlMembershipProvider, System.Web, Version=, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"










            passwordStrengthRegularExpression="" />



    <authentication mode="Forms">

      <forms loginUrl="~/Login.aspx" />




      <allow users="*"/>


    <pages theme="Cms">


        <clear />

        <add namespace="System" />

        <add namespace="System.Collections" />

        <add namespace="System.Collections.Specialized" />

        <add namespace="System.Configuration" />

        <add namespace="System.Text" />

        <add namespace="System.Text.RegularExpressions" />

        <add namespace="System.Web" />

        <add namespace="System.Web.Caching" />

        <add namespace="System.Web.SessionState" />

        <add namespace="System.Web.Security" />

        <add namespace="System.Web.Profile" />

        <add namespace="System.Web.UI" />

        <add namespace="System.Web.UI.WebControls" />

        <add namespace="System.Web.UI.WebControls.WebParts" />

        <add namespace="System.Web.UI.HtmlControls" />




            The <authentication> section enables configuration 

            of the security authentication mode used by 

            ASP.NET to identify an incoming user. 



            The <customErrors> section enables configuration 

            of what to do if/when an unhandled error occurs 

            during the execution of a request. Specifically, 

            it enables developers to configure html error pages 

            to be displayed in place of a error stack trace.

        <customErrors mode="RemoteOnly" defaultRedirect="GenericErrorPage.htm">

            <error statusCode="403" redirect="NoAccess.htm" />

            <error statusCode="404" redirect="FileNotFound.htm" />




  <location path="Management">



        <allow roles="Administrator" />

        <deny users="*"/>

Your connection string is using integrated security but you don't have impersonation in use so the account that runs as (Network Service in your case) is trying to connect to the database but doesn't have permission to. You can fix this by either:

1.) Give Network service permission to the database.
2.) Create a SQL Server login and have your connection string use that instead of integrated security/windows authentication.
3.) Enable impersonation on your website so that the service runs as a specific account or namely, the account that the user accessing the site is logged in as. This option will generally only work for you in an intranet environment.

try this

go to IIS --> your Web Site properties --> ASP.NET tab --> Change ASP.NET version to 1.1 and then change back to 2.0.
