Description Pancho 2018-05-07 01:56:50 UTC
I can create a DNS sub-domain very easily via the MS Active Directory Users and Computers snap-in.

...but once created, i cannot delete it.
Comment 1 Pancho 2018-05-07 02:01:40 UTC
To illustrate, I created a DNS domain called "frog" 

When I subsequently try to delete it via the MS snap-in, I get a popup that says:

The DNS domain cannot be deleted. This function is not supported on this system.

Then looking at the samba logs on the server, I see the following....

While trolling the web looking for a possible answer, or method to delete the sub-domain directly from Samba I came across the following


ie. the exact same problem.

I would greatly appreciate it if someone could tell me what i need to do in order to remove sub-domains. thanks

samba-tool dns query localhost ct.dummy.co.za @ ALL -U administrator

Results in the following output excerpt which includes my test "frog" sub domain.

 Name=ForestDnsZones, Records=0, Children=2
  Name=frog, Records=0, Children=0
  Name=fw1, Records=1, Children=0
    A: (flags=f0, serial=3, ttl=3600)
  Name=idp, Records=1, Children=0
