How to force IIS Express to run in 32 bit mode

There's a blog post up on the IIS team site now explaining how to enable remote connections on IIS Express. Here is the pertinent part of that post summarized:

On Vista and Win7, run the following command from an administrative prompt:

netsh http add urlacl url=http://vaidesg:8080/ user=everyone

For XP, first install Windows XP Service Pack 2 Support Tools. Then run the following command from an administrative prompt:

httpcfg set urlacl /u http://vaidesg1:8080/ /a D:(A;;GX;;;WD)

The answer like: string IIS_EXPRESS = @"C:\Program Files\IIS Express\iisexpress.exe";

    StringBuilder arguments = new StringBuilder();
    arguments.Append(@"/path:");
    arguments.Append(@"C:\Inetpub\wwwroot\ClientSyncService");
    arguments.Append(@" /Port:2000");
    Process process = Process.Start(new ProcessStartInfo()
        {
            FileName = IIS_EXPRESS,
            Arguments = arguments.ToString(),
            RedirectStandardOutput = true,
            UseShellExecute = false,
            CreateNoWindow = true
        });

Should work, however the trick is that you need to grant ACLs for the the identity of the service so that it can take ownership of port 80. In other words, during your setup program (assuming you have an MSI that will run elevated), make it run a command line like: netsh http add urlacl url=http://WhateverMachineName:80/ user=everyone

where you can limit "everyone" to instead just a specific account under which your service will be running. When you do that, then IIS express should be able to start just fine without requiring administrator privileges.
