[Samba] Demoted/removed a DC, and the NS records?

[Marco Gaiarin]

Following:
	https://wiki.samba.org/index.php/Demoting_a_Samba_AD_DC

i've demoted and removed a DC. Seems all went as expected:

 root at vdcud1:~# samba-tool domain demote --server=vdcsv1.ad.fvg.lnf.it  -U gaio
 Using vdcsv1.ad.fvg.lnf.it as partner server for the demotion
 Password for [LNFFVG\gaio]:
 Deactivating inbound replication
 Asking partner server vdcsv1.ad.fvg.lnf.it to synchronize from us
 Changing userControl and container
 Removing Sysvol reference: CN=VDCUD1,CN=Enterprise,CN=Microsoft System Volumes,CN=System,CN=Configuration,DC=ad,DC=fvg,DC=lnf,DC=it
 Removing Sysvol reference: CN=VDCUD1,CN=ad.fvg.lnf.it,CN=Microsoft System Volumes,CN=System,CN=Configuration,DC=ad,DC=fvg,DC=lnf,DC=it
 Removing Sysvol reference: CN=VDCUD1,CN=Domain System Volumes (SYSVOL share),CN=File Replication Service,CN=System,DC=ad,DC=fvg,DC=lnf,DC=it
 Removing Sysvol reference: CN=VDCUD1,CN=Topology,CN=Domain System Volume,CN=DFSR-GlobalSettings,CN=System,DC=ad,DC=fvg,DC=lnf,DC=it
 Demote successful

Following the wiki, now i'm cleaning the DNS, because still:

 gaio at hermione:~$ dig ns ad.fvg.lnf.it @vdcsv1

I've removed some entry (mostly, the GUID alias), but seems there's no
way to remove the NS record (right clinking it, there's no 'remove').

I need to click 'properties' and on the 'name server' tab, remove here?


Thanks.
