Folks

I've managed (due to me being fat-fingered that morning) to get a DNS zone in a Samba-4 DNS setup screwed up.

Basically I was trying to add a new A record to an internal domain "e2eservices.co.uk" using the MS administration tools (not the samba-tool CLI). However instead of adding the entry "styx" to the domain, I accidently added "styx.e2eservices.co.uk"; this basically generated a child entry called "uk" under the "e2eservices.co.uk" zone that appears to replicate all entries that where originally in the zone (so for example I now have "styx.e2eservices.co.uk.e2eservices.co.uk", "foobar.e2eservices.co.uk.e2eservices.co.uk", etc.

I'd rather lke to clean this up by deleting all of the records under "e2eservices.co.uk.e2eservices.co.uk"(including the child entries rooted at "uk.e2eservices.co.uk") without deleting any records under "e2eservices.co.uk" but cannot work out how to do this. I guess if absolutely necessary I could drop the domain and recreate it, but I'd prefer not to do this if at all possible. Does anyone have any suggestions on how I can go about doing this?

Thanks in advance

Alan

You could try samba-tool on the DC, 'samba-tool dns zonelist 127.0.0.1
-UAdministrator' will list all the zones, so if it is a separate zone,
you should be able to delete it with 'samba-tool dns zonedelete
127.0.0.1 <zone> -UAdministrator'

Thanks for the suggestion, however it is not a seperate zone, i.e. it appears to be a part of the "e2eservices.co.uk" zone with child objects (analogous to "_tcp" and "_udp" in a domain zone).

You will probably have to delete the dns records, one by one, try
investigating 'samba-tool dns --help'

Its should not be needed to drop and recreate.

Try the following.
Delete the created records in the "wrong" zone(s)
Try to delete the "wrong" zone. ( ignore the error)

Restart bind
Restart samba.

Pray and check again.
Are the "empty zones gone and are your dns records there again?

OK, not certain what has happened by the additional entries seem to have disappeared now.
