2008R2/2019 DC's. (process of retiring the 2008R2)
When querying source, it is either the root PDC or CMOS (on the PDC).
After changing the PDC to another server other servers were still pointing to the old PDC and the old PDC was still showing CMOS as the source.
2008R2 is the old PDC. 2019 is the new PDC.
Even after running the commands in this guide, the 2019 was till pointing to the 2008R2 and 2008R2 was still using the CMOS.

I would like my domain to use an external time service.
Thanks
