Good point. To that end, what happens if you try “w32tm /stripchart /computer:pool.ntp.org” from the PDC?

And probably not the Windows firewall. *From:* [email protected] [ mailto:[email protected] <[email protected]>] *On Behalf Of *Jimmy Tran *Sent:* Friday, February 3, 2017 10:50 AM *To:* [email protected] *Subject:* [NTSysADM] RE: can't set NTP time source on PDC It looks like the problem I’m running into is when I run “w32tm /resync /rediscover”. It gives me the error “The computer did not resync because no time data was available”, even after I follow the standard documentation to set the NTP server and to restart services. Event log shows it’s trying to connect to pool.ntp.org but it doesn’t receive a response. When I do this from my local PC it works. Perhaps there is something blocking it at the client site? Question is what…. Any thoughts? *From:* [email protected] [ mailto:[email protected] <[email protected]>] *On Behalf Of *Michael B.

It is current set to local but the time is off so I wanted to set it to an outside time source. When I run “w32tm /query /status”, it shows (source name: “LOCL”). So now I run “w32tm /config /syncfromflags:manual /manualpeerlist:pool.ntp.org /reliable:yes /update” and it completes successfully. I’ll restart the time service and do a query again but it still shows LOCL. I am doing this on the PDC on the domain. I’ve tried a reboot and even unregistering w32tm but nothing helps. I’m out of ideas. Thanks, JT
