You can get the proper ExitCode as described here. So the Windows Service Manager will give the right error text.

My OnStart in ServiceBase looks like this:

protected override void OnStart(string[] args)
{
    try
    {
        DoStart();
    }
    catch (Exception exp)
    {
        Win32Exception w32ex = exp as Win32Exception;
        if (w32ex == null)
        {
            w32ex = exp.InnerException as Win32Exception;
        }
        if (w32ex != null)
        {
            ExitCode = w32ex.ErrorCode;
        }
        Stop();
    }
}
