title: Error connecting to Informix using .NET driver
body: <p>I have a problem connecting to Informix server(windows) using ADO.NET. I'm using Listing 1 code from this article: 
  <a href="http://www.ibm.com/developerworks/data/library/techarticle/dm-0510durity/" rel="nofollow">http://www.ibm.com/developerworks/data/library/techarticle/dm-0510durity/</a></p>
  
  <p>Reported error is "ERROR [HY000] [Informix .NET provider][Informix]Invalid connection-type.". Error code is "-25539". </p>
  
  <p>From the error reference:
  "The connection-type is invalid for the database server. This message appears when the database server is configured to address specific connection requests, for example for an ER or HDR connection."</p>
  
  <p>After further searching I found that this is related with connection security levels but I don't know how to fix this.</p>
  
  <p>Also, Open Admin Tool successfully connected to server using same connection data used in .NET demo. </p>
  
  <p>I'm running windows 7 64bit and this SDK version: clientsdk.3.50.FC9DE.WIN.</p>
  
  <p>Can anyone help me with this?</p>
