Replacing the rather disappointing Windows Vista, Windows 7 promises to correct the flaws that made its predecessor so unpopular.<\/span><\/p>\n<p class=\"MsoNormal\"><span style=\"font-size: 12pt; line-height: 115%; font-family: &quot;Times New Roman&quot;,&quot;serif&quot;;\">One of the changes Windows 7 makes is that it automatically synchronizes the time using the Windows Time service located at windows.time.com. Whilst this is an <a href=\"https:\/\/www.atomic-clock.galleon.eu.com\/info\/ntp-servers-public\/ntp-server-uk-stratum-2.html\">accurate stratum 2 time server<\/a>, managed by Microsoft, it can be changed for another source of Internet time. However, even Microsoft recommend that Internet time sources should not used for computer networks as they can\u2019t be authenticated by the time protocol <a href=\"https:\/\/www.ntp.org\">NTP<\/a> (Network Time protocol). Furthermore, an internet time source needs a port left open in the firewall for the time signals to make it through. Any open port in a firewall can be used by a malicious user to gain access to the network.<\/span><\/p>\n<p class=\"MsoNormal\"><span style=\"font-size: 12pt; line-height: 115%; font-family: &quot;Times New Roman&quot;,&quot;serif&quot;;\">For a secure, authenticated and accurate method of synchronizing a Windows 7 network, then it is wise to use a <a href=\"https:\/\/www.galsys.co.uk\/categories\/network-time-server.html\">dedicated network time server<\/a>. Most of these time servers use the protocol NTP (Network Time Protocol) which can easily distribute a single time server throughout a network of hundreds and even thousands of machines.<\/span><\/p>\n<p class=\"MsoNormal\"><span style=\"font-size: 12pt; line-height: 115%; font-family: &quot;Times New Roman&quot;,&quot;serif&quot;;\">Time servers plug directly into the router\/switch for the network or can be installed on a single machine. Rather than rely on the Internet for a source of time and risk leaving the firewalls UDP port open, dedicated <a href=\"https:\/\/www.ntp-time-server.com\/\">NTP time servers<\/a> use either the GPS signals or long wave radio broadcasts transmitted from national physics laboratories such as the MSF signal broadcast by the UK\u2019s <a href=\"https:\/\/www.npl.co.uk\">NPL<\/a> and the USA WWVB signal broadcast by <a href=\"https:\/\/www.nist.gov\">NIST<\/a>.<\/span><\/p>\n<p class=\"MsoNormal\"><span style=\"font-size: 12pt; line-height: 115%; font-family: &quot;Times New Roman&quot;,&quot;serif&quot;;\">As these signals are external to the firewall and are able to be authenticated by NTP to establish the authority of the signals and are a more accurate and secure method of <a href=\"https:\/\/www.galsys.co.uk\">synchronizing a Windows 7 network<\/a>.<\/span><\/p>\n<p class=\"MsoNormal\"><span style=\"font-size: 12pt; line-height: 115%; font-family: &quot;Times New Roman&quot;,&quot;serif&quot;;\"> <\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Windows 7 is the very latest operating system from Microsoft.
