    Login failed for user 'NT AUTHORITY\NETWORK SERVICE'

    Hi Lijian / Adam,

    I just downloaded the latest CuteChatsetup.msi and installed with ease. I did a little change on the setup:
     
    1. my ASPDNF2's database is ASPDotNetForums, the app uses sql login to access database
    2. so on CuteChat "Web.Config" page, I edited the dbo prefix to "ASPDotNetForums.dbo"
     
    The CuteChat installation was done. but when I click on the Chat logo, I still can't open the chatroom page, it comes with this error:
     

    Cannot open database requested in login 'ASPDotNetChat'. Login fails. 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 requested in login 'ASPDotNetChat'. Login fails. Login failed for user 'NT AUTHORITY\NETWORK SERVICE'.

    Source Error:

    The source code that generated this unhandled exception can only be shown when compiled in debug mode. To enable this, please follow one of the below steps, then request the URL:

    1. Add a "Debug=true" directive at the top of the file that generated the error. Example:

      <%@ Page Language="C#" Debug="true" %>

    or:

    2) Add the following section to the configuration file of your application:

    <configuration>
       <system.web>
           <compilation debug="true"/>
       </system.web>
    </configuration>

    Note that this second technique will cause all files within a given application to be compiled in debug mode. The first technique will cause only that particular file to be compiled in debug mode.

    Important: Running applications in debug mode does incur a memory/performance overhead. You should make sure that an application has debugging disabled before deploying into production scenario.

    Stack Trace:

    [SqlException: Cannot open database requested in login 'ASPDotNetChat'. Login fails.
    Login failed for user 'NT AUTHORITY\NETWORK SERVICE'.]

       System.Web.UI.Page.ProcessRequestMain() +174
    

     

    But my ASPDNF2 uses sql login to access the database. Please help me in configuring this.
     
    Thank you and regards,

    Rgain,

     
    When you use ASP.NET, the default security context is the aspnet_wp account (or NetworkService account, for an application that runs on IIS 6.0) for both Aspnet_wp.exe (or W3wp.exe, for an application that runs on IIS 6.0) and the request to SQL Server.
     
    By default, the aspnet_wp account (or NetworkService account, for an application that runs on IIS 6.0) does not have any permissions in SQL Server, and therefore it cannot access the database.

     

    To resolve this issue, use any of the following method:
    Grant the correct permissions on SQL Server so that the aspnet_wp account (or NetworkService account, for an application that runs on IIS 6.0) has the appropriate access to the required resources.
     
    exec sp_grantlogin N'NT AUTHORITY\NETWORK SERVICE'
    go
    use ****
    go
    exec sp_grantdbacess N'NT AUTHORITY\NETWORK SERVICE'
    go

    Hi Adam,

     
    That works. I granted the IIS_WPG to both the ASPDNF2 and CuteChat databases, and used "trusted_connection" instead. Things worked out perfectly. Cheers, mate.
     
    As I recall, I saw a permission setting screen of CuteChatSample when I logged in as Admin. Where can I do the relevant permission settings in the integrated version? What do those checkbox options represent and how do they related to the ASPDNF2 roles / permission settings?
     
    Thanks
