Specify the time sources. Alternatively, a list of IP addresses can be specified. Select poll interval. Microsoft recommends a value of , which equates to a polling frequency of once every 15 minutes. Set the time correction settings. These settings specify a time frame to validate time stamps received from an external reference. Only if the received timestamp falls between these registry settings will they be accepted. We recommend time servers from Meinberg , but you can also find time servers from End Run , Spectracom and many others.
If you have a static IP address and a reasonable Internet connection bandwidth is not so important, but it should be stable and not too highly loaded , please consider donating your server to the server pool.
It doesn't cost you more than a few hundred bytes per second traffic, but you help this project survive. Please read the joining page for more information. If your Internet provider has a timeserver , or if you know of a good timeserver near you, you should use that and not this list - you'll probably get better time and you'll use fewer network resources.
If you know only one timeserver near you, you can of course use that and two from pool. It can rarely happen that you are assigned the same timeserver twice - just restarting the ntp server usually solves this problem. If you use a country zone, please note that it may be because there is only one server known in the project - better use a continental zone in that case.
You can browse the zones to see how many servers we have in each zone. Please help. Thanks, Donovan. Improve this question. Digital ink Digital ink 9 9 silver badges 21 21 bronze badges. Have you tried using wireshark to examine the network traffic? Maybe something else weird is going on? What does ntpq -p say? From my reading the time server in use should have an asterisk next to it. I engineered the config file to only have my single server and still no asterisk.
Server still looses time too. Also, ntpdate -[mytimeserver] will update the time appropriately. Add a comment. Active Oldest Votes. Newer and more modern versions, especially operating systems, have security features that make it harder for attacks to succeed, and the fact that they are still being supported means vulnerabilities are being fixed regularly. Microsoft ended support for Windows XP in April and Windows Server in July , but there are still over million legacy Windows systems still in use around the world.
It makes perfect sense, then, to worry about the possibility of widespread attacks against legacy systems when the ShadowBrokers revealed three hacking tools utilizing vulnerabilities in older versions of Windows in its cache of stolen hacking tools. Microsoft was clearly concerned that attackers, both state-sponsored and of the cybercriminal variety, could use these hacking tools in various campaigns, similar to the way the WannaCry ransomware, which included the ExternalBlue exploit code from the ShadowBrokers dump, used its worm-like capabilities to infect thousands of companies around the world in a very short period of time.
On the surface, the move smacks of a responsible company. Organizations that have been unable to move off legacy systems buy expensive extensive support systems. However, it also sends a disquieting message. One of the key reasons for upgrading when software enters end-of-life is to switch to a version that is still being updated.
