Hello, I'm configuring a Samba AD DC and there is an Bind error with a windows 7 member domain. When I start the win7 client, in the named.run file I've this : samba_dlz: starting transaction on zonedomain.com client 172.x.y.z#56880: update 'domain.com/IN' denied samba_dlz: cancelling transaction on zone domain.com samba_dlz: starting transaction on zone domain.com samba_dlz: allowing update of signer=win7pc\$\@DOMAIN.COM name=win7pc.domain.com tcpaddr= type=AAAA key=1148-ms-7.1-5408.45f6fed9-8e85-11e9-099e-d4bed99b32e7/160/0 samba_dlz: allowing update of signer=win7pc\$\@DOMAIN.COM name=win7pc.domain.com tcpaddr= type=A key=1148-ms-7.1-5408.45f6fed9-8e85-11e9-099e-d4bed99b32e7/160/0 samba_dlz: allowing update of signer=win7pc\$\@DOMAIN.COM name=win7pc.domain.com tcpaddr= type=A key=1148-ms-7.1-5408.45f6fed9-8e85-11e9-099e-d4bed99b32e7/160/0 client 172.x.y.z#60047/key win7pc\$\@DOMAIN.COM: updating zone 'domain.com/NONE': deleting rrset at 'win7pc.domain.com' AAAA client 172.x.y.z#60047/key win7pc\$\@DOAMIN.COM: updating zone 'domain.com/NONE': deleting rrset at 'win7pc.domain.com' A samba_dlz: subtracted rdataset win7pc.domain.com 'win7pc.domain.com. 1200???

I'm using RSAT to manage AD I begin in the samba AD world, so be understanding ;-) Thanks, Tom
