...ths users started noticing up to +/-6 minutes difference between their computers and the *real* time. Going to 'Date & Time settings > Sync Now' always gives "Time synchronization failed". For Windows 7 workstations, several years ago, I followed the advice in https://www.meinbergglobal.com/english/info/ntp-w32time.htm which was to do the following on the Windows 7 workstations: w32tm /config /manualpeerlist:mail,0x8 /syncfromflags:MANUAL w32tm /config /update Check the configuration: w32tm /query /source This worked and time was in-sync on the WIN7 computers for many years...

The flag "0x8" forces w32time not to send "symmetric active" packets but normal "client" requests which the NTP server replies to as usual." ref. https://www.meinbergglobal.com/english/info/ntp-w32time.htm --Mark

Hi, The Windows and Linux workstations are not synchronizing the time with the Samba 4 DC. I have verified that the problem is permission. I'm using Samba 4.6.3 on Debian 8. In this way the stations are with different schedules from the DC. Do I need to configure any GPOs? What is the maximum time the computer clock can differ from DC ? Regards, Márcio

We have a Samba-4.3 AD-DC hosted on a FreeBSD-10.3 system. We have just discovered that for some reason our domain workstations are not synchronising their time with the AD-DC. We have not altered the default GPO nor have we created a special GPO to handle time services. I have been working on several of the domain clients and I cannot seem to get them to source from the Samba server. I have

Hello all, I'm currently investigating the option to completely replace a SBS2003 DC with a Samba4 DC. My research (mostly on samba.org guides) shows that it is feasible, however I'd like to get feedback from the community on my goals. Current status: A Windows SBS 2003 is the PDC and a W2008 R2 server is acting as secondary DC. Domain operational level is 2003. There are ~40-50

...ba4 AD/DC to the real office LAN and boot. One by one, join each workstation to the domain. IMPORTANT! time synchronization needs to be maintained between the AD/DC and worksations. Of course, make sure ntpd is running on the AD/DC. However, Windows does not play nicely with ntpd, see: https://www.meinbergglobal.com/english/info/ntp-w32time.htm To fix this, log into the workstation as the domain administrator, get to a command prompt, and enter the following commands: > w32tm /config /manualpeerlist:mail,0x8 /syncfromflags:MANUAL > w32tm /config /update Add Domain Users In RSAT, Active Directo...

One of our STEM interns recently observed that there are inexpensive clocks that sync via radio to standard time services.? This begged a question about why every computer would not have a radio module to receive time.? Our senior staff did not have a good answer or if time from such a radio module would be supported by the operating system. When I was a student, such questions would have earned
