NTP Time Sync on Netware 5
WIth Netware 5.1:
For some reason, I am no longer getting correct time sync. Currently the server is set to use 0.pool.ntp.org:123; to get time. However, the Timesync debug screen tells me that the "NTP request packet timed out". I added two additional sources: 1.pool.ntp.org and 2.pool.ntp.org. No joy. I then tried NTP.NASA.GOV with the same results. The server can "ping" all these sites (with the ping utility).
Any ideas?

Thanks for your response.
Not sure why the Firewall needs ports open since the request is being generated from the inside of the LAN. You can ping all the NTP sites from the Novell server.
Our TimeSynce interval is set to 120 minutes.
We used to use a Stratum 2-level NTP source located more locally but had more trouble then with just the pool, so we took them off the list. However, I re-entered the address and found that it doesn't work now either.
Is an NTP service the only possible way to keep time updated? Can I use a Windows Serfer for the purpose?

Did you make sure your timesync interval is long enough not to have your IP blocked because you're "hammering" the time servers?
Have you checked to see if there is a tier-2 public server nearby, to use instead of pool? Often, a local university will have free, publicly-accessible time servers, and you'll get less latency and have less opportunity for problems out on the internet interfering with your timesync. For example, in the upper Midwest, the time servers at the University of Wisconsin are often easier to access with less latency and connenction problems than using pool.
Of course, that's a "for example" - I'm not recommending you use the UW time servers, especially if you have a closer public tier2 server available.
