I implement NTP with same scenario and it worked for me on first attempt.

I just configure all the switches to get time from master not from peers.

Hi, Are you running the VMs on Hyper-V? If so, then check that time sync(under integration .services) is disabled on the host. Could be your VMs are syncing with a host that has no time source. Thanks John

Hello John,

My VMs are running on Esxi hosts .

My switches are getting time sync from my DC. My Dc is also getting time sync from External Time server and acting as a internal time server.

Thanks

Hi,

What is the output of the following command on both VMs:

w32tm  /query /status

Thank

John

On DC Vm, It show me the external servers that its syncing, On other servers it shows My DC's IP.
