I have a small business that is using Cox Business with Server 2012, and we are getting DNS issues when trying to join computers to domain and no internet connection at times

DCDIAG gives me :

Warning: no DNS RPC connectivity (error or non Microsoft DNS server is running)

The info for the COX Modem is:

Internal IP    xx.xxx.203.150
Subnet          255.255.255.240
Gateway      xx.xxx.203.145
DNS   68.105.28.16

Router IP Local
192.168.2.1
Subnet - 255.255.255.0

DHCP - Disabled

What settings could be causing the issue in Server 2012 - DHCP/DNS

Depends on the DNS settings the clients are using. Do an IPCONFIG /ALL on the workstation in question and post the DNS lines for Primary and Secondary

Sorry - FROM Client - I have no idea where that other DNS is coming from

You might try flushing the cache from the server DNS and then restarting the DNS Service.

When I do a NSLOOKUP from the server (DNS Snap-in)

the default server says: UnKnown

>yahoo.com
Server: UnKnown
Address: 192.168.2.200

Non-authoritative answer:
Name:  yahoo.com
Addressses:   98.139.183.24
                        206.190.36.45
                        98.138.253.109


How do I get it to say the servername?

use the command "server <ipaddress>" or "server <servername>" otherwise, it defaults to the currently interface defined server. It should show the server name as unknown as default.

It was because there was no reverse zone setup.

However I now have 2 DNS servers on the same server

ICA-SRV

and

ICA-SRV.ICASUPPLY.local


I should delete one of them correct?

if they both point to the same physical, logical  or virtual DNS server, Yes... but it will not matter either way.
