You need to check if domain controller is syncing its time with external time source. If not you need to configure that. Then all computers in domain will get proper time from DC. You can read more on this topic here:<br />

You pays your money and you takes your choice when it comes to time synchronization across a domain.<br />
<br />
CASE A: &nbsp;If you use a local time server and require all systems to set from that server, then the times will be synchronized but there's no guarantee it will be correct. &nbsp;This appears to be what you're encountering. &nbsp;The time must be correct on the time server; if not, everybody has the wrong time and that can be catastrophic in environments where timestamps matter. &nbsp;And if the time server fails, nobody knows what time it is and the individual system clocks start to drift.<br />
<br />
CASE B: &nbsp;If you use a public time server net such as 0.us.pool.ntp.org, or a <a href="http://support.ntp.org/bin/view/Servers/StratumTwoTimeServers" rel="ugc">high-reliability Stratum 2 server</a> the times on each system will be close to correct but not exactly synchronized. &nbsp;On the other hand, the network time servers are always available (unless you lose internet connectivity) and are always very close to correct.

Thank Dariusz and Dr. Klahn for your answers. How can i identify what NTP setup this environment has?

Find PDC emulator: on a Root Domain DC run<br />

<pre><code class="code-1 nolinks" id="code-20-42479225-1"><span>netdom query fsmo</span>
</code></pre>
 &nbsp; &nbsp;<br />
Run the following command on the PDC emulator: <br />

<pre><code class="code-1 nolinks" id="code-20-42479225-2"><span>w32tm /config /manualpeerlist:timeserver /syncfromflags:manual /reliable:yes /update</span>
</code></pre>
 &nbsp;(where timeserver is a –space delimited– list of your time source servers)<br />
Once done, restart W32Time service.<br />
&nbsp; &nbsp; <br />
Run the following command on all other DCs (that are not PDC): <br />

<pre><code class="code-1 nolinks" id="code-20-42479225-3"><span>    w32tm /config /syncfromflags:domhier /update</span>
</code></pre>
Once done, restart W32Time service.<br />
<br />
NOTE: all w32tm commands are to be executed from an elevated command prompt by a Domain Admin of the relevant domain.

I recently took over a client and not too familiar with their setup. They have Server 2016 DC, AD, DHCP, DNS, File and Print. Time on all of the computers in the domain is off. How can i sync everyone's computers with correct network time?

Windows 10 is a personal computer operating system featuring the "universal application architecture" (UAP); apps can be designed to run across multiple devices with nearly identical code, including PCs, tablets, smartphones, embedded systems, Xbox One, Surface Hub and HoloLens. Windows 10 also includes a virtual desktop system, a window and desktop management feature called Task View, the Microsoft Edge web browser, support for fingerprint and face recognition login, voice-based search (Cortana), new security features for enterprise environments, and DirectX 12 and WDDM 2.0 to improve the operating system's graphics capabilities for games.

Microsoft Azure is a cloud computing platform and infrastructure for building, deploying and managing applications and services through datacenters. It provides both platform-as-a-service (PaaS) and infrastructure-as-a-service (IaaS) services and supports many different programming languages, tools and frameworks, including both Microsoft-specific and third-party software and systems. Cloud Services is a PaaS environment and can be used to create scalable applications and services; there are specific software development kits (SDKs) provided by Microsoft for Python, Java, Node.js and .NET. Azure also has file and storage services, data management, analytics and DNS services.

Windows Server 2016 is the successor to Windows Server 2012 R2. Built upon the same core code as Windows 10, Windows Server 2016 brings enhancements in security, servicing, and connectivity. A particular focus on this release was hybrid-cloud scenarios, and has close ties to Azure and other Microsoft cloud initiatives. This does not detract from the many improvements that are available for on-premises-only deployments

Windows Server 2016 comes in Datacenter, Standard, and Essentials editions, and for servicing, has adopted windows 10's cumulative model. The new nano-server install is designed to be remotely managed and is designed to be kept current through continuous feature updates. The full GUI install operates similarly to windows 10's "Long Term Servicing Branch" (LTSB) model with cumulative security updates.

Windows Server 2016 has also shifted from a per-processor-and-CAL licensing model to a per-core-and CAL licensing model. This brings Windows Server's licensing more in line with Microsoft's other products and makes hybrid-cloud license planning easier as well.

A domain controller is a server that responds to security authentication requests within a computer network domain. It is a network server that is responsible for allowing host access to domain resources. It authenticates users, stores user account information and enforces security policy for a domain
