Windows 10 Time Source

Last Modified: 2018-01-05
Hello Experts,

Recently I have deployed a secondary domain controller (Server 2012 R2) and after that deployment, some of our PCs in the office, keep changing their time to the incorrect time. I just realized that the time on the secondary domain control is off so I fixed that and I am hoping all will come into sync shortly. However, when I run this command w32tm /query /source on all of the machines in the office I am getting wildly different results. Some say time.windows.com, others Local CMOS Time, others the secondary domain controller, and others the primary domain controller. How can I make all of the sync to the primary domain controller?

I have tried this command, net time \\ServerName /set /y but this is only temporary, it reverts back to whateer it was. What is the end all be all fix for this issue?

The PCs in the office are Windows 10 Pro.

To force a computer to synchronize its time with a specific DC, you can run the Net Time command remotely or as a batch at logon:

net time \\<DC_name_or_IP> /set /y

Open in new window


w32tm /config /syncfromflags:domhier /update
net stop w32time
net start w32time

Open in new window


w32tm /resync

Open in new window


All of them should work. You can also combine them.

With all the respect of the other answers, I'd use the DHCP (windows) option to set that instead of setting it manually


004 specifies servers that provide TIME/ITP (as per RFC 868). This is not a recommended protocol/service in a Windows environment.

042 specifies servers that provide NTP/SNTP (RFC 1769).  This is the preferred time service in a Windows environment (assuming the absence of Active Directory which maintains the time on your behalf.

Virtual DC? If so disable host time sync
