Portal alias not working

I have installed 3.2.1 and cannot get the portal alias to work despite following the instructions. Have I misunderstood something? Here is my configuration.

Installed at www.myhost.com/dnn which works fine.
Have pointed www.mydomain.com to resolve to /dnn directory on my host
Have added the 2 aliases www.mydomain.com & mydomain.com to the Portal aliases
Have cleared the cache at Host>Host Settings>Advanced settings>Performance Setting

Every time I try to load the portal using www.mydomain.com I get the following error

Server Error in '/' Application.

Object reference not set to an instance of an object.

Any ideas where I am going wrong?

Re: Portal alias not working

I haven't solved the original problem above but have got a workaround. My host is 1and1.co.uk and I have just discovered that you can have multiple domains on your account and use virtual directories, but if you have multiple .NET applications things get screwed up which is what is causing the above error.

I have made a workaround which uses redirects based upon the requested url placed in the root dir, code below for those that are interested
private void Page_Load(object sender, System.EventArgs e)
   {
      if (Request.Url.Host.ToLower().IndexOf("myfirstdomian.com") >= 0)
   {
      Response.Redirect("/first");
      Response.End();
   }
      else if (Request.Url.Host.ToLower().IndexOf("myseconddomain.com") >= 0)
   {
      Response.Redirect("/second");
      Response.End();
   }
   else
   {
      Response.Redirect("/first");
      Response.End();
   }
}

By pointing each domain to the root the redirects work as follows

www.myfirstdomain.com displays in the browser www.myfirstdomain.com/first

www.myseconddomain.com displays in the browser s3432473.myhost.com/second instead of www.myseconddomain.com/second

If anyone knows how to configure this differently I would be grateful for the help. Otherwise does anyone know of a good different hosting provider who doesn't have this screwy setup for .NET applications?

Re: Portal alias not working

Hey Spid,
I'm not quite sure about your scenerio, so I'm probobally going to over-explain a little bit. :)

1) Install DNN into its own directory.
2) Create a Virtual Directory (application) for the site
3) (set up all the db stuff - you already know how to do that)
4) browse to Site.com/{Application}

You do always have to have dnn in an app directory, however, some host require that it run from a child directory (site.com/app) instead of a root directory (site.com). With Alaises, you'll want to give it the application URL that you want to be able to access your site from.

If you're looking for a good host, I would 100% recommend www.PowerDNN.com . They really know DNN inside and out (they're platinum DNN benefactors) and their tech support is virtually always free as well. They'll set you up and everything for nothing. Also, they're in the process of setting up a streaming video server for hosting and DNN questions. Its really pretty sweet.

Re: Portal alias not working

Are both of the applications you are trying to run DNN? By that I mean are you trying to run two different sites both using DNN?

Re: Portal alias not working

Mr.MobileNow: The setup I have is running from a child directory. What I have discovered while changing things about is that when 2 different web apps are installed, 1and1's IIS gets screwed up and doesn't seem to know which page to serve and throws an exception. e.g. both have a Default.aspx within each seperate child dir.

Also had a look at PowerDNN but I'm looking for more than just a host for DNN (See below)

Adeian: It isn't both DNN. I develop my own .NET web apps and have just moved to 1and1 beacuse it seemed a good deal for the features (50Gb monthly traffic & 200 external domains & 1500 imap/pop3 email being just a few for £13.59/month = $24). Have been transferring domains across one by one and have now found this problem which means it wasn't such a good deal after all if you intend to run multiple .NET apps. Doesn't make much sense to me but they must have some weird IIS configuration.

I am going to phone their tech support once more and if I don't get any joy I will continue my search for a better UK based hosting provider as I am unhappy with 1and1's 20+ minute wait before getting through to tech support as well.
