How to Set NTP Server on Windows Server?
Accurate time synchronization is essential for event logging, network security, and smooth system operations. The Network Time Protocol (NTP) can be configured on various versions of Windows, such as:
- Windows Server 2022
- Windows Server 2019
- Windows Server 2016
- Windows Server 2012 R2
- Windows Server 2012
- Windows 11
- Windows 10
You can use the Windows Time service to synchronize time across a network through two simple methods with NTP.

Steps to Set NTP Server on Windows Server
Network Time Protocol (NTP) is an internet protocol designed to synchronize computer clock times across devices within a network.
Once you’ve purchased buying Windows VPS, you can follow one of the methods outlined in this guide to enable NTP on your Windows Server. Let’s dive in!
Step 1. Open Registry Editor
Open the Start menu and look for the “Run” application in the search bar.Once it opens, type “regedit” into the text box and press Enter.
A window similar to the one below will appear.
Step 2. Find NTP Server Files
Follow the below path to go to the NTP Server Configuration:
Computer>HKEY_LOCAL_MACHINE>SYSTEM>CurrentControlSet>Services>W32Time>TimeProviders>NtpServer.
In the image below, you can see the end of the tree structure. The files we are looking for are visible in the right pane.
Step 3. Enable NTP Server
To open a small window, double-click the “Enabled” file. In the window that appears, find the section labeled “Value data.” As demonstrated below, change the value from 0 to 1.
After changing, click “OK”.
Step 4. Create the AnnounceFlags 5
The trustworthiness of a computer as a time server in Windows is governed by a specific entry. If a computer is not designated as a time server, it cannot be recognized as reliable. For domain members, the default setting is 10.
The default value for stand-alone clients and servers is 10.
Follow the path below:
Computer>HKEY_LOCAL_MACHINE>SYSTEM>CurrentControlSet>Services>W32Time>
To go to the ”Config”:
Computer>HKEY_LOCAL_MACHINE>SYSTEM>CurrentControlSet>Services>W32Time>Config.
On the right pane, as seen above, you will find a file with the name “AnnounceFlags” while there.
Double-click it. That will cause a tiny window akin to the one in Step 3 to open.
Change the value from a to 5 under “Value data“.
Step 5. Restart NTP Server
By pressing the Windows key and typing “Services,” the “Services” window will appear.
Look for “Windows Time” once it has opened. Click “Restart” from the context menu when you right-click on it.
Step 6. Open UDP port 123 in the Firewall
Your Windows Server must have UDP port 123 open for NTP to connect to the clocks. Please check your firewall configuration if you can’t reach the servers.
To complete this step, follow the synchronize time with host windows server 2022 guide. Remember that this port is UDP and not TCP.

Set-ItemProperty -Path “HKLM:\SYSTEM\CurrentControlSet\Services\w32time\TimeProviders\NtpServer” -Name “Enabled” -Value 1
Create the AnnounceFlags 5
Set-ItemProperty -Path “HKLM:\SYSTEM\CurrentControlSet\services\W32Time\Config” -Name “AnnounceFlags” -Value 5
Restart NTP Server
Restart-Service w32Time
Run the command below to allow NTP port: (If Firewall is running)

-Name “NTP Server Port” `
-DisplayName “NTP Server Port” `
-Description ‘Allow NTP Server Port’ `
-Profile Any `
-Direction Inbound `
-Action Allow `
-Protocol UDP `
-Program Any `
-LocalAddress Any `
-LocalPort 123
