Record in default vod application

Hi!
I'm trying to record a  video to the default FMS vod application with a flash movie, i'm getting this error: "NetStream.Record.NoAccess".

I think the problem is not in my code, but just to make it sure, here is it:

var mycam:Camera = Camera.getCamera();
mycam.setMode(320,240,25);
var myvid:Video = new Video(mycam.width,mycam.height);

myvid.attachCamera(mycam);
stage.addChild(myvid);

var conn = new NetConnection();
conn.connect("rtmp://192.168.1.104/vod");
conn.addEventListener(NetStatusEvent.NET_STATUS, statHandler);

function statHandler(event:NetStatusEvent) {
     if(event.info.code == "NetConnection.Connect.Success") {
          conn.addEventListener(AsyncErrorEvent.ASYNC_ERROR,function(){});
          var stream = new NetStream(conn);
          stream.client = new Object();
          stream.attachCamera(mycam);
          stream.publish("testrec","record");
     } else {
          trace("error in connect");
     }
}

So i want to ask that do i need any configuration to use NetStream.publish("xy","record") on the server?

i checked and the connection to the server is fine.
if i use live streaming, than it's fine (of course in this case i use the live application).
It's maybe a file system related problem. I use windows 7, and given all permissions for all the users.. still dont working.

I think it can be a FMS configuration issue.
