Problems creating a session from a machine other than the headnode

[Marcel Bruins (marcel.bruins)]

When trying to run the sample for the FirstSOAService an error occurs when the program is deployed to any other machine than the head-node.
I compiled the following code :
---------------------------------------------------------------------------------
namespace Microsoft.Hpc.SOASample.FirstSOAService{
using System;
using Client.ServiceReference1;
using Microsoft.Hpc.Scheduler.Session;
using System.Collections.Generic;
using eNose_Aethena.Generic;
using eNose_Aethena.Generic.Datasets;

class Program {
static void Main(string[] args){
SessionStartInfo info = new SessionStartInfo("ENO-AP5", "CalculatorService");
using (Session session = Session.CreateSession(info)){
Console.WriteLine("Session {0} has been created", session.Id);
using (BrokerClient<ICalculator> client = new BrokerClient<ICalculator>(session)){
AddRequest request = new AddRequest(1, 2);
client.SendRequest<AddRequest>(request);
client.EndRequests();

foreach (BrokerResponse<AddResponse> response in client.GetResponses<AddResponse>()){
double result = response.Result.AddResult;
Console.WriteLine("Add 1 and 2, and we get {0}", result);
}
client.Close();
}
session.Close();
}

Console.WriteLine("Done invoking SOA service");
Console.WriteLine("Press any key to exit");
Console.ReadKey();
}
}
}
---------------------------------------------------------------------------------
Running this code on the Head Node results in the following output
---------------------------------------------------------------------------------
Session 56 has been created
Add 1 and 2, and we get 3
Done invoking SOA service
Press any key to exit
---------------------------------------------------------------------------------
This is the expected output.

Trying to run the code on any other machine ( I tried my develop machine and a Compute Node inside the Cluster) result in the following error
---------------------------------------------------------------------------------

I can not find what might be causing this error..
I'm sure it shoud be possible to run this code from another machine.
