W32tm /query /status This enables you to see the current performance of the time service, including its connection to the NTP server Troubleshooting Steps If the w32tm /resync command faults, or the w32tm /query /status shows that the system is still using a CMOS clock, then the NTP server is likely blockedWindows 08 R2 Domain Controller (PDC)Use w32tm /query /source to see what the current running source is If the Windows Time service is unable to contact the configured NTP server, this may return "Local CMOS Clock" or "FreeRunning System Clock" Otherwise, it will return the NTP server or the DC that the server is currently syncing with

W32tm /query /source local cmos clock domain controller-Then I run a w32tm /query /status and generally get something like this as a response Two completely different domains and servers respond with the source Local CMOS Clock Leap Indicator 0(no warning) Stratum 1 (primary reference syncd by radio clock) Precision 6 (ms per tick) Root Delay s Root Dispersion sAlready restart and reregister the PDC w32time service, configure the poolntporg peerlist successful, but when query status still pointing to Local CMOS Clock When query configuration, type is 'NTP' and NTPServer is 'poolntporg' No group policy about time server
At an elevated command prompt, enter "w32tm /query /source" On the authoritative server, this should return one of the time servers you entered in the Peers registry key For a domain computer, it should list the authoritative domain server you specifiedW32tm /query /status This will display the following output (it will either state Source Local CMOS Clock or timewindowscom) After working out the souce and that it was synching without error as well as the obvious the fact the time was way off I needed to find a reliable Time serviceVM IC Time Synchronization Provider — then your domain controller with the PDC role is a virtual machine that synchronizes the time with the host

Check it with W32tm /query /configuration You may have to repeatedly run it a few times until you see it change from the CMOS clock to the time server you set it toNTP on root domain PDC falls back to local cmos on reboot Hi guys!Check 3 – Configuring another NTP and Check Status Changes , It Could be NTP not giving the time in a proper way So that Windows Server puts back to default Local CMOS Clock Check Event Viewer
However, if you check the current time source (w32tm /query /source), you can find it unexpectedly, because you can see a strange time source named VM IC Time Synchronization Provider The fact is that HyperV virtual machines synchronize their time with the host by default, and regardless of the settings of the time service inside the machineSo what do you get when you run the w32tm /query /peers command?Still the status shows Local CMOS Clock Please advice how we can point ntp to our firewall Regards Shijith windowsactivedirectory w32tm /query /source w32tm /query /configuration (I'd drop the 0x8 at least for testing)please don't forget to Accept as answer if the reply is helpful
Right now, the PDC gets it's time from the local CMOS clock We can see this if we issue the bellow command which queries the system time and gives us some useful information w32tm /query /status To configure the PDC Emulator with an external NTP server or hardware appliance for that matter, just use the bellow command line and execute itW32tm /query /source If you see in the output Local CMOS Clock — the time source on this server is its local hardware clock;NTP server time showing local CMOS clock I'm having issues setting an external source on a Windows 08 R2 domain controller (PDC emulator role for the domain) Here is the output showing its source is the Local CMOS clock C\Windows\System32>w32tm /query /status Leap Indicator 0(no warning)

Check it with W32tm /query /configuration You may have to repeatedly run it a few times until you see it change from the CMOS clock to the time server you set it to If it doesn't change after a few minutes, you may have to reset the time service in the Contingency section below Windows 00Seems like I am still using the local CMOS clock despite all the setup That is at least what w32tm /query /source says Just to be sure I used the tool PortQueryUI to check that udp port 123 was open from the NTP Client to the NTP server, and it is I have also tried this as described here and then restart time services"w32tm /qeury /source" showing local cmos clock If you have a valid source setting, try to resync once and see if this change If it does not change, the possible reason is same as "no time data was available" issue above VIA DHCP Option 004 and option 042 The description for 004 is "Time Server", while 042 specifies NTP Servers
