How to configure all the computers in your Windows domains for proper time synchronization. Time Server Settings in a Windows Domain. Microsoft operating systems and server applications have become increasingly dependent on proper time synchronization. A skewed system clock can affect your ability to log on, can cause problems with mail flow in Exchange, and be the source of a great many difficult to locate problems. GPResult-5.png' alt='Active Directory Users And Computers Gpupdate Switches' title='Active Directory Users And Computers Gpupdate Switches' />To compound matters, the default method of handling time synchronization within a Windows network isnt exactly reliable or even predictable. If a Hyper V hosts clock becomes out of sync, it usually affects all of its virtual machines, sometimes catastrophically. Fortunately, it doesnt take a lot of work to get everything in sync. Pick a Computer to Server as the Authoritative Internal Time Source. The first thing you want to do is decide what machine you want to serve as the authority on time within your domain. In most cases, I choose the domain controller that holds the PDC emulator role. According to Microsofts documentation, thats supposed to be the highest authority on the matter anyway, although it doesnt seem to work out that way in practice. The machine that you choose will be regularly consulting Internet sources, so if youre in a high security facility you might consider relegating this role to a different computer. You could have multiple machines serving as authoritative time sources, but more than one per site is generally unnecessary. You could also have one machine pull external time and have your PDC emulator use that as its source while still serving as the authoritative server for the rest of the computers in your domain. Firewall Information. Time synchronization traffic travels on UDP port 1. Your authoritative server will need that port open inbound. All clients, including the server, will need it open outbound, at least to the authoritative hosts IP. Configure the Authoritative Computer. You can use any computer or device that runs an NTP server. This post will only discuss how to set it up for a Windows Server computer. The steps are well documented in Microsoft Knowledge Base entry 8. Scroll down to the section titled Configuring the Windows Time service to use an external time source. There is a Fix it for me button, but I recommend that you go to the Let me fix it myself section and click on Click here for directions about how to resolve this issue yourself. This will show you exactly what youre doing and where. Be advised that this involves registry editing which is always something to be done cautiously and even moreso when it is on your PDC emulator. In step 4c, when it asks for peers, I use the following. Once youve done this, the changed computer will periodically announce that it is an authoritative time source. In reality, this announcement probably wont be received by most of your domain computers. Configure DHCPIf youre using a Windows domain, I always recommend using Windows DHCP. Since you really only need a single source, it is easiest to set this as a server option, although you certainly could establish it on each individual scope as a scope option. Set options 0. 04 and 0. Time Options in DHCPWith DHCP entries, you can only use IP addresses. You can type the name of the server in and click Resolve, but it will always insert an IP address. If youre serving DHCP using a Cisco device, inside the configuration for the DHCP scope enter the following commands option 4 ip 1. Obviously, substitute your actual NTP server for the IPs in those commands. For other NTP servers, consult the manufacturers documentation. Now, all DHCP devices will pick up the internal NTP server configuration at their next refresh. Unfortunately, a lot of Windows units wont pay much attention to that, although most DHCP client devices will. Configure Static Devices and Non Windows Computers.

We will harden the system. I read nothing in that linked article that says it is a user issue. It is talking about the computer accounts not user accounts. Follow the instructions in that. Most devices, such as NAS and SAN equipment, have a place to enter NTP server information. For most Cisco IOS devices, enter ntp server 1. For non Windows computers, consult the operating systems documentation. In general, this type of equipment wont be as concerned with the accuracy of its clock as Windows computers, so you may opt to skip this. Determine How You Wish to Handle Virtualized Guests. All modern hypervisors have the ability to provide time synchronization to guest machines through that hypervisors integration tools. If enabled, guest machines will draw time from the physical host they are running on. In most cases, youll want to disable this feature for Windows Server guest machines that are serving as domain controllers. For all other guests, its a judgment call. I have personally not encountered problems using time synchronization, provided that the hosts clock was properly maintained, but other administrators have found it necessary to disable synchronization. Can T Install Io Shield Back. However you choose to handle this, the important thing is to ensure that you are consistent. For a Hyper V guest, open its Settings dialog box and open the Integration Services tab. Clear or set the check box for Time Synchronization as desired. For other hypervisors, consult the manufacturers documentation. Hyper V VM Time Synchronization. For virtualized domain controllers, especially on Hyper V Server 2. R2 and later, you must disable the Time Synchronization service. While you will find references to partially disabling the service, it is no longer effective. Set Group Policy. To really convince your Windows computers to use your authoritative time server, youll want to use group policy. First, if your domain is not already configured to use specialized organizational units OUs for its computers, set them up now. You cannot link a group policy object to the default Computers OU. There is no right way to set these up, so devise a scheme that makes sense for your organization. There is no benefit to being overly complicated, so aim for simplicity. You can always reorganize and expand later if you determine that you werent complex enough. For this post, your general aim is to segregate computers that need to have a defined time server from those that dont. For instance, if you have laptops that will primarily be used at sites not controlled by you, you might wish to not set any time servers for them at all, or you might wish to have them rely on the same Internet sources as your authoritative system. You may need to set up different time servers for different physical sites and ensure their local computers refer to the local source. If youve decided to let your virtual machines receive their time through synchronization, you definitely want to ensure they are not conflicting with group policy. Use the Active Directory Users and Computers tool to create these OUs. You can drag and drop computer accounts from one OU to another or you can right click on them and select Move. Warning Never move a domain controller from the Domain Controllers OU. This will cause all sorts of problems, and not all of them are easy to troubleshoot. To set the policy, open the Group Policy Management tool on a domain controller or on a computer running Remote Server Administration Tools. Expand your domain. Right click on Group Policy Objects and click New. Give your new policy a name that indicates what it will do, such as NTP Client Main Site. Click OK. New GPORight click on your newly created GPO and click Edit. This will launch a new window with the group policy editor.
