Will Setting type Option 042 in MS DHCP Server Scope interfere with AD time service?

Question

I have a well functioning AD domain and time service that is provided without specifically setting dhcp option 042 for time services. But we have phones, and Macs and tablets and all sorts of other devices that won't pick up time from the PDCe. So, we're considering delivering time server information via DHCP. But I am planning on using a time server that isn't the PDCe but another local peer of the PDCe. (Yes, I know I could use the PDCe as that time server, and depending on this question's answer that may be my solution.)

My question revolves around is it a problem to put in a Server Scope option 042 that is not the PDCe? Will the windows desktops and laptops in the directory try to go to the option 042 provided time server, or will they continue to go to the PDCe as normal? Couldn't find anything specific on this topic.

Thanks.

Hi,

If there is no Active Directory which maintains the time, then DHCP option 042 is the preferred time service in a Windows environment.

If DHCP option 042 and PDC exist at the same time in domain, it might cause an unnecessary complexity.
