Hi all,

I've been having problem trying to setup DNN backup files on the server.

The backup database was restored to the server, and PortalAlias is not empty.

Can anyone help suggest what might be the problem?

Thanks
Jean

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.

Anyone researching this problem may come across various postings saying that all portal aliases must be listed seperated by commas. This is not correct, each alias requires a new row in the database.
