Can you have two domain controllers on the same network?

Actually, In a larger environment, at least two domain controllers at each physical site should be DNS servers. This provides redundancy in the event that one DC goes offline unexpectedly. Note that domain-joined machines must be configured to use multiple DNS servers in order to take advantage of this.

How do I use two domain controllers?

To configure additional domain controllers. On the server that will act as a domain controller, in Server Manager, on the Dashboard, click add roles and features. On the Select Server Roles page, select Active Directory Domain Services. Click Add Features when prompted, and then click Next three times.

How many domain controllers are there in one network?

There should be a minimum of two DCs in a domain. If you only have one domain, all your DCs should also be GCs….Answers.

Can I run multiple domains on the same physical network?

you can run multiple domains in the same physical network. BUT you have to make sure that no conflicts occur for domain members with ip addressing for the DNS servers. So using DHCP for all will create problems, because maybe domain1 machines gets ip information belonging to domain2.

Is there a way to share a DNS address between two domains?

There will be no trust established between them unless you manually establish one. The DHCP issue is a valid point, and your potential fix is correct – You can hand out the DNS address of one domain via DHCP, and use a forwarder to resolve the other domain’s namespace.

Can one domain use multiple fixed IP addresses in one subnet?

So one domain has to use complete fixed ip addresses when they are in one subnet. Of course the fixed ip addresses have to be excluded form the DHCP scope.

How to assign only one domain to another domain?

Assign only one domain’s DNS servers via DHCP. On those DNS servers either set up conditional forwarders for the other domain or create a stub zone for the other domain. I haven’t done this so I’m not 100% positive that it would work, but I can’t think of any reason it wouldn’t.
