I studied your videos on installing DNN 3.2 to a shared host with interest. I have run into difficulties trying to install DNN402 on my dedicated server.

The test site I have created runs fine on local development system (XP Pro, VWD 2005 Express, SQL Server Express 2005). I have left web.config with the default settings so the database (database.mdf in app_data) is attached temporarily.

I have created a site on the W2003 server using IIS6, set the NTFS permissions so that IUSR_WPG has full access to the directory, and ftpd the entire site unchanged.

When I try to run it I get the dreaded Object reference not set to an instance of an object message, and the details say:

[NullReferenceException: Object reference not set to an instance of an object.]
   DotNetNuke.Entities.Portals.PortalSettings.GetPortalSettings(Int32 TabId, PortalAliasInfo objPortalAliasInfo) +125
   DotNetNuke.Entities.Portals.PortalSettings..ctor(Int32 tabId, PortalAliasInfo objPortalAliasInfo) +83
   DotNetNuke.HttpModules.UrlRewriteModule.OnBeginRequest(Object s, EventArgs e) +3797
   System.Web.SyncEventExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() +92
   System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) +64

Version Information: Microsoft .NET Framework Version:2.0.50727.42; ASP.NET Version:2.0.50727.42

I have been puzzling over this for 3 days without success. I suspect it is permissions based. Presumably SQL Server Express takes care of the permissions (I have installed a very small .NET 2.0 site using the standard web.config method of dynamically attaching and it works without a problem, so the difference may be in the DNN side)

Any clues please?

Hi John, I'm afraid I haven't installed v4.x to a live server yet, so I can't really offer any advice. If you are trying to install a version that you have already created at localhost level, I would suggest that to begin with you just install DNN4.0.2 using the install zip file to double check that you can get DNN4 to actually install on a live server, at least that may start to give you a few clues as to what the problem is. If this still doesn't provide any answers I would suggest asking in the main DNN forums to see if anyone can provide any information. When you find the answer, I would appreciate it if you could let us know the solution. - A video for installing 4.x to a live host is on the cards and it will help if there are already some key tips to watch out for. Thanks,
