Question Cannot join domain on Win 10 Clients, but Mac clients can

[Benkberg97]

Hi all,

I recently installed a Windows Server 2019 DC and setup a static ip of 10.0.0.85 for the DC. All of my Macs can join the domain, but on the Windows 10 PCs, I get the dreaded, "An active directory domain controller could not be contacted... Domain does not exist." I can ping the DC by hostname and IP address, but nslookup on the hosts states that it cannot find kleinberg.local (the name of my domain.) All hosts have their DNS settings set to point to the IP address of the DC. Same issue when trying to use the NETBIOS name. When pinging the DC by hostname, I get a link local IPV6 address response. I am wondering if the issue pertains to IPV6 causing issues. NSLOOKUP also shows the domain name of my Comcast modem on the hosts. No firewall rules are configured as well. Should I disable IPV6 on all the Windows hosts or is something else wrong with DNS? Thanks!

can you browse the DC from your PCs through explorer?

Yes, I can browse the shares on the DC through File Explorer on all of the Windows 10 hosts and the Mac OS hosts.

Are these Windows 10 Home systems, by any chance? Windows Home editions can't be added to a domain.

Nope. All hosts are running Windows 10 Pro X64.

Disable IPv6, and add the server IP and name to the hosts file, see if that helps.

Disabling IPv6 on the Windows 10 host worked! Must be an issue with that on the other hosts.

Make sure DNS service is running on the server. Before joining the workstation, set it to use that DNS. This worked for me on 2012/2016.
