Windows 10: Switching NTP Client from one NTP server to another

Hello all,I am struggling a bit with NTP synchronization and seeking some help.I configured a windows server as an NTP server. And I configured several clients to sync their time with this server.Now I am finding a small skew between one of the clients PC-A and the server after a couple of months.When i try to resync, it always shows sync successful. And it shows me the IP address of the server in the adjust date/time page. But when i run the command w32tm /query /configuration, it shows me the IP address of the NTP server to be a different machine lets call it PC-B.Now, this rogue PC-A an

NTP Help

Hi guys, I know this is not the site for bull**** networking but you've been the most reliable tech site I've ever been on for any computer stuff. So I've got a question about a network. I'm with the Marines, and we're running secure networks branching off from everywhere. I mean I'm in Japan right now. But we're trying to sync our hardware (Cisco devices, switches and routers) to NTP. I created a test setup with a router, easy as pie to sync that, but it was a direct connection from the router to our linksys gateway directly to the ISP. But in the real setup, we pull NTP data on every piece of hardware I set up to sync...we just don't sync. "Show NTP associations" shows full reach, stratum 3 servers all working perfect but our offsets are off (I'd love to know what the numbers for offset mean), but show ntp status shows no synchronization, not even a hint that it realizes it's got a working NTP server to pull off of. NTP is supposed to be an easy setup, but for over a month now myself and everyone I know have tried everything from our end to get a sync and we got nothing. Maybe it's not close enough to the NTP time, so we set the time and timezone a billion times, nothing there. I'm assuming since we can pull data from NTP servers, the port's gotta be open right? If it's impossible to sync because somewhere along the way a firewall is blocking it's UDP port, that's totally cool, then I'll have an excuse as to why we're gonna have to manually set clocks. But the fact that it pulls information (diagnostics at least, ping, offset, freq, stratum) I feel like we should be able to pull time, we just can't for some reason. If you guys have any idea what I can do please let me know. Thank you

W11 Pro NTP Client Fails

If you go to Windows settings > Time & Language > Date & Time > Additional Clocks > Internet Time > Change settings > you should be able to manually try any listed NTP server.

The Windows.com one never works for me so when I've seen this problem I use the other listed one. That's all I got for that as that's all that's ever been (as far as I've ever seen).

A note on that Python script which I feel is not correct way of thinking here. Its not checking NTP the same so its rather worthless. The script you linked is only trying from the router assigned IP "client.sendto(data, (addr, 123)) where addr='192.168.99.1'" while more correctly would be connecting to an NTP server directly as in this linked script: "client.sendto( data.encode('utf-8'), ( NTP_SERVER, 123 )) where NTP_SERVER = "0.uk.pool.ntp.org"" Python Network Programming Cookbook - Second Edition Mind you that I don't really care what the router is doing there.

Hope the best
