I have uploaded my DNN files to my web hosting account and setup the database according to the installation documentation. When I navigated to my domain name with my browser the DNN installation screen came up and I started the installation. Most of the installation was fine, but toward the end, it came back with an error saying it couldn't complete the installation. I then navigated back the home page, and recieved the following error:

DotNetNuke Error   Domain Name Windows Vista 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: 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. 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 tried to modify the URL in the PortalAlias Table, but because there isn't a user in the Portal table, I couldn't insert the URL.
