How To Configure Ntp Server In Windows 7

What is NTP server? The concept is quite familiar to the people of information technology, Code ... but for those who step in, it is quite a strange concept. So if you are looking for NTP server, let's find out with BKhost.

What is NTP server?How To Configure Ntp Server In Windows 7 (1)

Network Time Protocol (NTP) is a protocol for synchronizing the clock of a computer system through a packet-switched data network with variable latency. When clients send time synchronization requests to the server, the servers will update with each other to be able to sync the most accurate time to the client.

This protocol was designed to avoid the effect of variable latency by using a jitter buffer. Also called NTP's software is deployed in a NTP Public Services Project (NTP Public Services Project).

How NTP server works

  • The NTP client sends a packet, which contains a card the arrival time to the NTP server.
  • The NTP server receives the packet, and sends the NTP client back another packet, with a time tag from the time it sent the packet.
  • NTP client receives the packet, then calculates the delay, based on the time tag it received along with the delay of the transmission line, the NTP client will automatically reset its time.

Can backup data according to schedule

It must be said that backing up data is extremely important in any system and if that system goes wrong for a long time it will lead to backups - backups become inaccurate.

Help speed up the access network

Many devices now use "cache" attached to a large-area file system, based on "timestamp" - a timestamp that can determine whether the version of the data corresponds to the current time. .

If you do not synchronize the time correctly, the cache server system will not function properly, leading to the use of the wrong data.

Network management system

When errors or problems do arise, you need to check the system log as a major part of debugging. Failure of time synchronization between these log files will make you spend more time figuring out the cause to fix.

How To Configure Ntp Server In Windows 7 (2)

When your system shows signs of unauthorized network intrusion, check how your network is compromised, what range of data is accessed can be checked quickly and accurately if you There is a time log of the login - login on the router or on the server. Or if you don't have a server, you can learn how to create a virtual one to use.

Normally, the chances of hackers will delete the log right after that is high, but if you do not delete it, you can identify and track the compromised time.

Regulatory compliance

Regulations such as Sarbanes Oxley, GLBA or HIPAA and many more will be needed in the future, so the accuracy in data and time of transactions is a certainty.

The simplest guide to configure NTP Server

Step 1: Stop the Windows Time service in Services

  • In the StartMenu section, go to Services
  • In Services, find Windows Time and stop the service

Step 2: Conduct editing W32time in regedit

  • Go to Run and type Regedit.

HKEY_LOCAL_MACHINE -> SYSTEM -> CurrentControlSet -> Services -> W32Time -> TimeProviders -> NtpServer

  • Edit the Enabled value with Value data = 1
  • Under W32Time -> Config -> AnnounceFlags, change Value data = 5.

Step 3: Proceed to restart the W32Time service

Under Services, select Windows Time. Then proceed to Start the service again. Or access cmd then use the command: net stop w32time & net start w32time

Step 4: Configure Firewall Firewall

Turn off Firewall or open port 123 UDP

Step 5: Configure the time above the NTP Server, note the standard time zone set

For example: NTP Server has Vietnam time zone using UTC +7: 00 Bangkok, Hanoi, Jakarta or GMT +7.

NTP Client uses Win 7, XP, Linux ...
Go to Time -> Internet Time -> Change settings ...

  • In the server section, enter the IP of the NTP Server. Then choose Updatenow, you will get the following results:
  • Meanwhile, the NTP Client side has synchronized the time with the NTP Server.
    With WinXP, users conduct the same Internet time update
  • For Linux, please update using the command ntpdate 192.168.1.78.

In case NTP Client has synchronized with NTP Server but is out of time zone. Users need to update the standard time zone on NTV Server side.

After the article that BKhost introduces to you, you can see the NTP server and the NTP server configuration - time synchronization is extremely important for your system, worth investing in and helping to improve security. as you can more easily manage your system. In addition to being able to refer to a cheap server machine is also a reliable address for you to choose.
