Maybe I'm too tired but I have trouble understanding. So you're saying
that if I leave the check there, and some time down the road decide to
change an IP, it will register the correct IP back to the computer name.
But didn't we just establish that this update is not happening? Or are
there multiple types of DNS registration, such as dynamic and non-dynamic?
And thanks for the advice about the GPO, I will look into that.
By the way, just to be on the safe side: I'm using Samba internal DNS,
without any customizations, version 4.31.
