Time synchronisation in Domain controllers and connectivity server
Hiii,
I have 2 Domain Controllers DS-01-A and DS-01-B. Connectivity servers are SNTP master and Domain servers are SNTP slave.The server times are not synchronising. In DS-01-B, the time is changing automaticay to some other time(there is a difference of 2-3 minutes wrt DS-01-A) and then it will come back to the same time as DS-01-A. This is occuring continuously.
What could be the reason and how to resolve this issue?
Voted best answer
Chapters "Enable the SNTP Server, Disable SNTP Client in a PC" for the connectivity server and "Configure Time Synchronization in a Dedicated Domain Controller" for the domain controllers?
I have similar configuration and it works well.

Windows Time (W32Time) is very informative in Windows Event Log. Is Win32Time reporting the time source and any synchronization attempts?
Registry keys must be correct - not only IP-address is required, also changes to type and enable flag settings are needed. The w32tm.exe command is documented, try reading up on the tool.
Examine and eliminate any competing time sync protocol from running in client mode on DS-01-B
Are you running virtual machines?
If you are using VMware observe that there are several issues with time sync.
For instance the default syncronization setting in WMware Tools...
BR and Good Luck!

Run this command on the domain server,
w32tm /monitor in a dos window. the output will tell you the time difference between the servers and where their reference is. you can also read up/google the output of this command to understand it.
