Thanks a lot for all of your responses. I really appreciate your spending time in this matter.
It seems like that my organization's traffic controller was blocking all NTP requests. I contacted them and was able to use the organization's NTP server.

Thanks for the detailed instructions. ---- Nazmul On Tue, Jul 10, 2012 at 1:37 AM, unruh <[email protected]> wrote: > On 2012-07-09, Dave Hart <[email protected]> wrote: > > On Mon, Jul 9, 2012 at 21:00 UTC, unruh wrote: > >> If he is having trouble keeping many second sync with pool servers, he > >> is going to have trouble with keeping sync with a master.
