Windows service and Nhibernate

Question

I have a Windows service which has a timer and in the timer_Elapsed event handler a method from another component will be called which is supposed to look into db and get or update some records.This process will happen every 2 minutes.I used nhibernate for data access in the component. When I run the method from unit test it is working fine which means the configurations and mappings are correct, but from windows service I get this exception:

FluentNHibernate.Cfg.FluentConfigurationException was caught

Here is the code in timer_elapsed event handler:

private void timer1_Elapsed(object sender, System.Timers.ElapsedEventArgs e)


   {
        lock (processLock)
        {
            DoWorkComponent component= new DoWorkComponent ();
            component.DoWorkMethod();
        }
    }

Does anybody know how this can be fixed? Do I need to have different settings?

Thanks in Advance,

Problem solved. The error was related to the user account that runs the service:
