I successfully installed DotnetNuke with SQL Server 2008 Express.  When I clicked a Go To Site link I received this message:

Domain Name Does Not Exist In The Database

DotNetNuke supports multiple portals from a single database/codebase. It accomplishes this by converting the URL of the client browser Request to a valid PortalID in the Portals database table. The following steps describe the process:

1. Web Server Processing
   
   • When a web server receives a Request from a client browser, it compares the file name extension on the target URL resource to its Application Extension Mappings defined in IIS.
   • Based on the corresponding match, IIS then sends the Request to the defined Executable Path ( aspnet_asapi.dll in the case of ASP.NET Requests ).
   • The aspnet_isapi.dll engine processes the Request in an ordered series of events beginning with Application_BeginRequest.
2. HttpModule.URLRewrite OnBeginRequest ( UrlRewriteModule.vb )
   
   • The Request URL is parsed based on the "/" character
   • A Domain Name is constructed using each of the relevant parsed URL segments.
     
     Examples:
     
     URL: http://www.domain.com/default.aspx = Domain Name: www.domain.com
     URL: http://209.75.24.131/default.aspx = Domain Name: 209.75.24.131
     URL: http://localhost/DotNetNuke/default.aspx = Domain Name: localhost/DotNetNuke
     URL: http://www.domain.com/virtualdirectory/default.aspx = Domain Name: www.domain.com/virtualdirectory
     URL: http://www.domain.com/directory/default.aspx = Domain Name: www.domain.com/directory
     
     
   • Using the Domain Name, the application queries the database ( Portals table - PortalAlias field ) to locate a matching record.
     
     Note: If there are multiple URLs which correspond to the same portal then the PortalAlias field must contain each valid Domain Name in a comma seperated list.
     
     Example:
     
     URL: http://localhost/DotNetNuke/default.aspx
     URL: http://MACHINENAME/DotNetNuke/default.aspx
     URL: http://209.32.134.65/DotNetNuke/default.aspx
     PortalAlias: localhost/DotNetNuke,MACHINENAME/DotNetNuke,209.32.134.65/DotNetNuke
     
     Note: If you are installing the application to a remote server you must modify the PortalAlias field value for the default record in the Portals table according to the rules defined above.

 

 I don't know what to do now.  Thanks for any help and God Bless,

Hi Sam,

Answer to you first question: When DNN shows "Domain Name Does Not Exist In The Database" Error that means the url you are using to access the website does not exists inside portalalias table. For example if the url is http://www.example.com the in portalsalias table there should be an entry of example.com for portal id 0 (main website).

For assigning permissions to your website as far as I know you need to give full control to NetworkServices and ASP. This is enough for a DNN website to work. Hope this helps.
