>>The only thing different for me is I don't want to dispose the timer when I stop it. Because I have a bit of processing to do on the timer interval, I want to suspend the timer while I do the processing and then start it back up again when I am done. I also may need to adjust the delay time if the previous service access wasn't successful so there is more time elapsed before trying again. The best I have come up with is to do a timer.Change(Timeout.Infinite, this.QCheckInterval); and then set a new time again after the processing is complete.

Sorry, not sure what you mean. If you want to pass in the delegate, you can do that with something like this:

        private void SetTimer(System.Threading.Timer timer, int delaySeconds, int intervalSeconds, TimerCallback callback)
        {
            if (timer == null)
            {
                using (AutoResetEvent autoEvent = new AutoResetEvent(true))
                {
                    TimeSpan delayTime = new TimeSpan(0, 0, 0, delaySeconds, 0);
                    TimeSpan timerInterval = new TimeSpan(0, 0, 0, intervalSeconds, 0);

                    timer = new System.Threading.Timer(callback, autoEvent,
            delayTime, timerInterval);
                }
            }
            else // Reset Timer
            {
                timer.Change(delaySeconds, intervalSeconds);
            }
        }

Then just add a few overloads to remove the unnecessary parameters.
