        I'm assuming at one point when I do something "right" this dc should appear in my windows dc like @scottalanmiller mentioned, however; definitely not currently there.

          Right, those two IP addresses don't match. Meaning something is wrong with the DNS system. I notice that your workstation is using Google as its primary DNS server. That should be pointing to your DC or on-site DNS server which is authoritative to your zone. Can you ping 10.10.25.10 from your workstation?

            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)

                But then they would miss out on the valuable practice of setting it up themselves.

                  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.

                        inet = internet

                          Server: hostserver.pricehouse.ca
                          Address: 192.168.1.10

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

                            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

                                      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.
