title: ASP.Net Application deployment on Windows Server 2003
body: <p>I'm trying to deploy an ASP.Net application I developed to a Windows Server 2003 System but I get a error message when running the Site.</p>
  
  <p>The first thing is that I get a Null Reference exception when I want to access my custom configuration section. So I figured that maybe the System.Configuration Assembly might not be installed. However I removed the reference and included the database directly into code to see if it works without.</p>
  
  <p>But now I'm getting another error that a third party server control is not recognized.</p>
  
  <blockquote>
    <p>Error Message: Server label
    "trirand:JQGrid" unknown.</p>
  </blockquote>
  
  <p>The same application runs just fine on my XP machine with IIS 6 installed so I wonder if I'm missing some installation. This is the first ASP.Net Application on that machine as before there were only ASP tools. I think that the .Net Framework 3.5 SP1 is installed but I'm not sure. Another question is if the ASP.Net is integrated into the .Net Framework of if I need a different install package.</p>
  
  <p><strong>Update:</strong></p>
  
  <p>I experienced a weird behaviour: I added the obviously wrong element <code>&lt;asdf&gt;</code> to the web.config file. On my development machine that gave me the expected error, but on the server nothing happened at all. So it seems like it some does not recognize my web.config file.</p>
