We have an old Ubuntu box running as an NTP server and as part updating our systems we are planning to decommission it. However, this system has been set as the local machines NTP server via DHCP scope options and via group policy. If I just switch it off then all the Windows clients or any DHCP client on the network will not know where to get the correct time from and could cause connectivity issues on the domain.
I have tested a new GPO on an isolated machine to see what the effects are and not a lot changed, the client machine effected by this new GPO just reports DC01 as the NTPServer when I run w32tm /query /configuration and reports the source as being local CMOS clock when i run w32tm /query /status. Is this normal?
Running the same thing on my PDC shows the clock as being Free running system clock, should this be set to an online time service, or should it not matter (as long as the clients are only getting their time
from the PDC?
What I would like to know is is there a best practice guide somewhere I can read through?
I have been trawling various searches but can't seem to find anything relevant.
