[Samba] samba-tool gpo listall error

[Jonathan Kreider]

My google fu quickly turned up this info:
https://unix.stackexchange.com/questions/564673/wheres-my-stub-resolve-conf-missing

which suggests that I need to start systemd-resolved.service.

However, since this is an AD DC, I want samba to provide the DNS. So I've
disabled systemd-resolved.service.

I suppose that the anti-systemd crowd will go into fits about this. Does
anyone have a solution?

Thanks,
Jonathan Kreider
