I try to create a Windows Service which listens to UDP port 514, i install it using installutil.exe and i get the following error message:

The SyslogService2005 service on Local Computer started and then stopped. Some services stop automatically if they are not in use by other services or programs.

In practise it starts working till the progressbar in Properties Window ends!

my code:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Diagnostics;
//using System.Linq;
using System.ServiceProcess;
using System.Text;
using System.Net.Sockets;
using System.Net;
using MySql.Data;
using MySql.Data.MySqlClient;
using System.Threading;
using System.IO;

namespace SyslogService2005
    public partial class Service1 : ServiceBase
        public Service1()
            this.ServiceName = "SyslogServiceUDP514";
            this.CanStop = true;
            this.CanPauseAndContinue = true;
            this.AutoLog = true;

        private const int listenPort = 514;

        class UdpState
            public UdpClient u;
            public IPEndPoint e;

        public static bool messageReceived = false;

        public static bool processWorking = false;

        public static void ReceiveCallback(IAsyncResult ar)
            UdpClient u = (UdpClient)((UdpState)(ar.AsyncState)).u;
            IPEndPoint e = (IPEndPoint)((UdpState)(ar.AsyncState)).e;

            Byte[] receiveBytes = u.EndReceive(ar, ref e);
            string receiveString = Encoding.ASCII.GetString(receiveBytes);

            //Console.WriteLine("Received: {0}", receiveString);
            messageReceived = true;


        private static void StartListener()
            // Receive a message and write it to the console.

            IPEndPoint e = new IPEndPoint(IPAddress.Any, listenPort);
            UdpClient u = new UdpClient(e);
            UdpState s = new UdpState();
            //LogMessageToFile("s.e = e");
            s.e = e;
           // LogMessageToFile("s.u");
            s.u = u;

            //Console.WriteLine("listening for messages");
                //LogMessageToFile("Start Asychronous");
            while (processWorking==true)
                u.BeginReceive(new AsyncCallback(ReceiveCallback), s);

                // Do some work while we wait for a message. For this example,
                // we'll just sleep
                while (!messageReceived)
                    //LogMessageToFile("Sleep 100 ms");


        static void LogMessageToFile(string msg)
            System.IO.StreamWriter sw = System.IO.File.AppendText("C:\\Services\\LogFile.txt");
                string logLine = System.String.Format("{0:G}: {1}.", System.DateTime.Now, msg);


        protected override void OnStart(string[] args)
            // TODO: Add code here to start your service.
            //LogMessageToFile("Service Started");

            processWorking = true;

            //ThreadStart job = new ThreadStart(StartListener);
            //Thread thread = new Thread(job);
            //LogMessageToFile("StartListener Started");

        protected override void OnStop()
            // TODO: Add code here to perform any tear-down necessary to stop your service.
            if ((Thread.CurrentThread != null) && (Thread.CurrentThread.IsAlive))
                processWorking = false;

                LogMessageToFile("Service Stopped");


Does it work if you tell it it can interact with desktop, or if you run it as you rather than a local service account?

i created a console application with the same functionality and it is working properly!
What the **** with the windows service! The service manager cannot understand that it started ... :(

Depending on which OS and wether you're part of a domain etc, windows 2003 for example is common to have it so you cannot interact with the desktop.. if it thinks for any reaosn you might, the service doesnt work.

What type of interaction? (Development is on Windows Vista)
In most tutorials in OnStart section they create just a event in EventLog or they write service started in a txt file ("Service Started") and they create another event in OnStop section... I just have more functionality in my case...
