That would be great, because I've just cleaned up about 40 entries using the Windows DNS Manager gui tool!

I also learnt a lot about adding extra NS and PTR records using this gui tool (mydomain.com and _msdcs.mydomain.com), which would be nice to be able to do using 'samba-tool'.

I have rebooted both DCs and tested logins and DNS. Everything is now definitely quicker without those old DCs in the DNS and AD.

I can now perform the same cleanup on the live production network this weekend.

Thanks,

:)
