Primary DNS for Member server

[Majstor]

Hello,

Recently I joined a member server to domain. When I tried to join it for the
first time it was refused because "Preferred DNS" was not DC.
After I changed that setting to DC IP address, it was OK.

Now that member server is joined, mayI change "Preferred DNS" to other DNS
servers?

Regards,
Vladimir

If by 'other DNS' you mean an ISP DNS server then the answer is no. In
Active Directory, the DNS server used by both servers and workstations alike
must be a local DNS server that holds a copy of the SRV records for your
domain.

What is the goal here Vladimir?

If you need the workstation to be able to get to the Internet, configure
forwarders on your DC/DNS server to point to the ISP:

1. Open the DNS console
2. Right click on the server name under DNS and select Properties.
3. Select the "Forwarders" tab.
4. Select "Enable forwarders" and enter the IP addresses for your ISP's DNS
servers.

If you need DNS resolution to another network, forwarders can also work for
this, but I would recommend adding a secondary zone for this network on your
DNS server.
