        Sorry ignore the initial nslookup that was done at work.

        Second one was done at home, my router is set to point to google.
        Then when I add computers to my domain I change it to my home based DC.

        Should I change the DNS entry to 104.167.119.11 or to my home based 192.168.1.10
        (or both)

        Can you do

        ip addr
        

        On your Samba server? That should tell you what the public IP address is, compare that to your results... although you really shouldn't be doing LDAP over the public internet... I guess if you were doing LDAPS it wouldn't be so bad but... still...

            The previous command queries all interfaces on your server. It then pulls the requested info. In this instance we were looking for the IP address. So the lo interface, or local loopback, has the 127.0.0.1 address. Whereas the ens33 interface, or ethernet interface has the ip address of 104.167.119.11. It also shows the IPv6 addresses as well.

            That IP address matches the one for nslookup so DNS is matching. Although from your home workstation you should use your DC as your primary DNS lookup and Google as the secondary.

                So changing home computer to

                192.168.1.10
                8.8.8.8

                I get

                C:\Users\admin>nslookup dc.pricehouse.ca
                Server: hostserver.pricehouse.ca
                Address: 192.168.1.10

                *** hostserver.pricehouse.ca can't find dc.pricehouse.ca: Non-existent domain

                so thats interesting

                  Your hostserver is authoritative for that domain. So you will need to add a DNS entry for it.

                      @Sparkum Right. On the Windows DC, which your workstation is now pointing to, you need to create a A record for the Samba server. That won't fix the issue you are having but you should be able to ping it now.

                        Absolutely correct

                        C:\Users\admin>nslookup dc.pricehouse.ca
                        Server: hostserver.pricehouse.ca
                        Address: 192.168.1.10

                        Name: dc.pricehouse.ca
                        Address: 104.167.119.11

                        full pings

                            So the CentOS firewall is installed, but it won't run, or it is running and dropping traffic. Can you try:

                            firewall-cmd --state
                            

                            It should return running, not running, or command not found.

                              With Centos 7, I believe you should be using "systemctrl" instead of "service".

                              sudo systemctl enable firewalld
                              sudo systemctl start firewalld
                              sudo systemctl status firewalld

                                Yep it will redirect the service commands but it's depreciated.

                                  State is definitely not running.

                                    Well for some reason when I got home and started to re-try everything after confirming the service was indeed stopped, suddenly I could start it, and complete step 8 with success....

                                    Still not a DC but progress for sure

                                      So at this point I would have to assume that there is a mistake in on smb.conf file eh?

                                      Just going through the checklist

                                      Installed samba ....... Yep
                                      smb.conf file .........Prob?
                                      Made samba/anonymous.....yep
                                      Firewall steps........yep

                                      Can access it from windows comp.......No
                                      See it in my domain......No

                                          I don't think you have an eth0 interface. At least not from the previous screenshot. I believe your interface is called ens33. Although I could be mistaken. Also your hosts allow option isn't going to let your workstation connect to it as it isn't in one of those subnets.
