title: CruiseControl.NET force build not working from CCTray
body: <p>I really hope someone who is a CC.NET expert can help with this, because this problem is painful!</p>
  
  <p>I have a remote build machine with CruiseControl.NET and CCTray running (version 1.5.7256.1)</p>
  
  <p>On the local machine I have CCtray connecting through HTTP not .NET remoting.
  When I configure the projects, I add a server through HTTP and use the following URL:</p>
  
  <p><a href="http://localhost/ccnet" rel="nofollow noreferrer">http://localhost/ccnet</a></p>
  
  <p>If I leave [Set to pre-1.5.0 server] UNCHECKED, then it fails to connect with this error:
  <strong>Failed to connect to server: The remote server returned an error: (500) Internal Server Error.</strong></p>
  
  <p>If I set to [Set to pre-1.5.0. server] CHECKED, then it succeeds and I can kick builds off from CCtray on the local machine fine.</p>
  
  <p>Now, if I go back to another machine which I want to connect remotely, I follow same steps. Again, only pre-1.5.0 setting works. WHY?! CruiseControl.NET and CCTray are at 1.5.7256.1?!?</p>
  
  <p>The 2nd problem and main problem which I think may be related to the previous; if I then use the pre-1.5.0 setting the pojects show up but when I force a build I now get this error:</p>
  
  <p><strong>An unexpected error has occurred while trying to force a build.
  The method or operation is not implemented.</strong></p>
  
  <p>What am I doing wrong, I'm really struggling with this. I previously was using 1.4 versions and this worked fine, so has something broken? I'm using IIS7 too so don't know if this could be something to do with it.</p>
