More than one domain on the same network?

We are wanting to test an Exchange server.  Currently we are on Lotus Notes.  Research show that Exchange needs to be installed on a domain with Active Directory.  

Are there any issues with creating a second domain on the same network with an already active domain on it?  

I don't see an issue but thought I'd ask and get second opinions.  


                Thanks..

Hello,

As long as the new domain doesn't share the same namespace with the original domain, you will be fine.

Yes you can have more domains in the same IP subnet. You just have to make attention that clients are accessing right DNS servers and domain controllers.

You can also set up DNS and DHCP services on one of the servers on the new Domain and then disable those services. That way you have them configured and can test at your leisure by turning those services on and off as needed. Having two domains is absolutely fine but do not duplicate any server names or IP addresses.

As far as DNS and DHCP go.  DHCP would be the only one I'd have to worry about right?   As long as I don't point my production clients to the test DNS domain there is not fear of running DNS on the test box full time right?  I know DHCP will hand out IP's if I leave it up.

Yes, you are right. If you will have just one DHCP, just be sure that production clients will be pointed to production DNS server. For test environment you will also need test DNS servers, but you can configure test clients manually and set them to point to test DNS servers.
