SharePoint 2007 - Creating a web application in C# gives Error Access Denied at Provisioning

Question

I am trying to create a SharePoint web application (on SharePoint2007) in C#. How differently I tried, it ends up with the same access denied error in the Provisioning step. The error message does not contain much details. It only says COM Error : Access Denied. Below is my code.

      SPWebApplicationBuilder webAppBuilder = new SPWebApplicationBuilder(SPFarm.Local);
      webAppBuilder.ServerComment = "App1";
      webAppBuilder.Port = 81;
      webAppBuilder.RootDirectory = new DirectoryInfo(@"C:\Inetpub\wwwroot\wss\VirtualDirectories\81");
      webAppBuilder.UseNTLMExclusively = true;
      webAppBuilder.AllowAnonymousAccess = false;
      webAppBuilder.UseSecureSocketsLayer = false;
      webAppBuilder.ApplicationPoolId = "SharePoint - 81";
      webAppBuilder.IdentityType = IdentityType.NetworkService;

      webAppBuilder.CreateNewDatabase = true;    
      webAppBuilder.DatabaseServer = "abcdef"; //Database server   
      webAppBuilder.DatabaseName = "WebApp81";  // Database name

      SPWebApplication newApplication = webAppBuilder.Create();
      newApplication.Provision(); //Provision it into web farm 

The last line is the one that gives the error. Access Denied.

I'm using a domain account. When I investigated a little bit more I saw,

• The database and the set of tables are created.
• At SharePoint admin page web application lists, the application is listed.
• But I can't create a site collection in it (Since Provisioning has not properly been completed)

Have someone got any idea of what I am missing here?

Thanks a lot...

Try to execute this code with a domain account who has privilege on your SharePoint Farm.

In which context do you run this code ? via an event receiver ? feature activation ?
