Getting Error on start method of windows service

I have created a windows service by using (Visual Studio 8) and installed it by using installutil.exe tool, however I am not getting proper result from it as I did the following code on service start method.

protected override void OnStart(string[] args)
{
    FileStream fs = new FileStream(@"e:\mcWindowsService.txt",
        FileMode.OpenOrCreate, FileAccess.Write);
    StreamWriter m_streamWriter = new StreamWriter(fs);
    m_streamWriter.BaseStream.Seek(0, SeekOrigin.End);
    m_streamWriter.WriteLine("m ready buddy");
    m_streamWriter.Flush();
    m_streamWriter.Close();
}

Instead of creating file in E Drive it is showing Following Error when I am staring it !

The Test Service Installer service on Local Computer started and then stopped. Some services stop automatically if they are not in use by other services or program.

I'm almost positive your code crashes. The try-catch suggestion above is the best so far so you can see what blows up.

Further: Try to not execute stuff that takes a long time in the OnStart - only light initialization stuff. There's a timeout and if you go past that treshold Windows will complain that it cannot start it - it will remain in Starting state which is annoying. In OnStart start just a timer and execute your heavy stuff in the handler of the expiration event of that timer's interval timer_Elapsed. Before you execute your stuff pause the timer and start it back after the operation ended.

If you run the service from the a console, then make sure that your account has permissions on the E driver.

If you have installed your service, and realized that it threw the exception, then set the account type for the service installer like 

var serviceInstaller = new ServiceProcessInstaller();
            serviceInstaller.Account = ServiceAccount.LocalSystem;

Put the above code in Try-Catch block, write it to event log for any exceptions and investigate it. Also would be good to put them in separate thread to avoid any block.
