I have a small network of 35 computers all in one location. We have a comcast cable modem that acts as our Gateway, DHCP, and I assume our DNS since I'm using a Novell 5.1 file server only.
I would like to migrate to a Windows Server 2008 R2 and use active directory which would require us to have the server run DNS. This server will not be accessible on the web. It will be a LAN only.
Since I won't be putting this server on the WEB do I have to use a registered domain name? Can I just use: corp.buisnessname.org? (as an example). Do I need to do anything with the comcast cable modem? It currently points to a static IP address and 2 DNS addresses. Does my DNS once active on the 2008 R2 Server take over for this? Do I point the server to the modem/router?
Is there a simple step by step guide out there? I would think with this being the most basic of setups for server 2008 R2 there would be a nice step by step guide out there. Do I need forward look up zones with this simple a setup? Would really appreciate someone directing me to a simple and plan instruction manual on this type of setup. Once setup up I plan on using this as a simple file server only. Nothing else. I don't like the delays with workgroups...we need the security of active directory.
