I'm experiencing a new crazy issue.  I have about 9 MAC computers on a network with mostly Windows PCs.  I have a windows 2012R2 DC, with AD, DNS, DHCP, etc...
If the Macs use a static IP, everything works fine, the hostname stays what is configured by the user.

As soon as I change the manual IP to DHCP on the MAC, after a reboot, the hostname of the PC randomly changes to a windows PC name.
It's completly random, as different MACs use different windows PC names.   Where do I even begin to troubleshoot this issue.

I am running different versions of the mac, on most of the macs, i'm running Mojave.  A few are running Catalina.
