      ….
      I am testing with IE 8.0 on Windows 2003 Server DC.  I even did a Reset to Factory and selected recommended default settings.

      A browser on a server edition doesn't "eat" a captive portal like that (mine, on a 2008 R2 did finally, but had to fiddle my OS somewhat - don't recall very wel).
      Use a vanilla OS like … well, any OS with their navigators except "servers".

      Tried with a Win 7.  I get the CP Login redirection but is not displayed, instead gives me a "Diagnose Connection Problems" error page.  The address bar clearly shows the CP Login address.

        At that moment, was was your IP address of the Win 7 PC  ? Who gave it to you (was it pfSEnse who gave it - check wth the pfSense DHCP Lease list and log)
        What is the gateway IP ? (THis IP should be the one that pfSene uses as the Captive portal).
        What is / are your DNS ?

        No "help me" PM's please. Use the forum, the community will thank you.
        Edit : and where are the logs ??

          The WEin 7 PC is a Domain attached computer. The Domain Controller is DC/DNS/DHCP Server.  The PC IP is given by the DC.  The gateway IP is the pfsense server IP.
          Pfsense DNS is on default configuration.  When CP is off the PC gets the DNS resolution from the DC succesfully. The DC gets the DNS resolution from pfsense also.  I made the IP and the name of the pfsense server an Allowed IP/Host in CP.

          Some times Chrome does not redirect either when openned.  I have to write in the address bar the http address manually to trigger the CP redirection.  I guess that is because chrome tries to get the home page from its cache.

          Some time IE redirects to CP Login, but after login it fails with a no connection error.

            Domain what where ???

            From what I made of it when pfSEnse + Captive portal was made :
            An interface (NIC) on which the captive portal is running.
            A wire from this NIC to a switch.
            This switch goes to wall-mounted RJ45 plugs (back then, some devices didn't have Wifi build in !) and a bunch of Access Points (wire to radio devices).
            My visitors bring allong there PC / Pad / Phone / whatever (a basic BJOD).

            Example : by a NEW Dell portable - Phone or whatever. Unwrap it. Connect to the Wifi network. pfSense portal kick in - and it works.

            Now, back to your 'domain' (from Microsoft ?) PC. This isn't a typical BJODevice …...

            Do de test yourself : Your smartphone - the AP and your pfSense portal => That works ....

              I am currently in testing.  I have a Virtual network of DC and PC in LAN side and pfsense VM with fixed IP on LAN side and WAN DHCP assigned IP.  CP listens in LAN interface. DC (Windows 2003 server) has Firefox, Chrome, and IE 8.0 browsers, PC (Win 7) has Chrome and IE 8.0 browsers.  There are no wifi clients.

                Notice that now, when CP Login is shown successfully, after doing the Login the PC fails to ping external sites (www.google.com) like being blocked.  I checked the CP status and the MAC address of the PC is registered successfully and active. So it should not be blocked.

                  Your portal interface is on an interface - probably named initially OPTx.

                  Please list the firewall rules (see GUI this time !) and gives us YOUR rules for this interface.
                  Remember : by default, LAN has ONE rule : let all pass. By default, all other interfacse have ONE hidden rule (the list will be empty) : BLOCK ALL.
                  Do you let in ICMP ? ("in" because it's from the point of view of the interface).

                    I do not have OPT interfaces, only LAN and WAN.  I think ICMP is allowed.  When I have CP off I can ping from inside to outside successfully.  With CP on I can ping the pfsense LAN IP.

                      I notice that I can ping the site which triggered the CP Login not other.

                      Example. 
                      I Open browser (Chrome).  The home page fails to load and does not trigger the CP Login.
                      I write in the address bar a http address (http://www.jetsystemservices.com).  The CP Login is triggered. 
                      I login successfully and the site is shown.  (External links in the site fails, youtube links)
                      I go the command prompt in the browser computer and I can ping the www.jetsystemservices.com site. But I cannot ping other address.

                      It is like CP only allows one address at a time instead of opening all internet.

                        Is this the locally build page that doesn't need any 'internet' access -
                        or
                        is this a page like http://www.google.com (and NOT https://www.google.com !!! ) that comes from the net ?

                        at that moment, go here https://doc.pfsense.org/index.php/Captive_Portal_Troubleshooting
                        and list us your ipfw rules and tables (what IN these tables)

                        also, at that moment:
                        open command prompt
                        and
                        ping www.yutoube.com

                        The URL is resolved ?
                        The ping replies ? (youtube.com might decide not to reply, that's ok)

                            Now I think got worst.

                            I reinstall pfsense 2.3.1 amd64 from cero, even format the HD to make sure no files remained.  Did not install any package. I set the LAN IP static, WAN IP takes IP from Cable modem DHCP.  I turn off DHCP on LAN interface as the LAN side takes the IPs from the Windows Domain DHCP server.

                            Added CP zone, with Local Authentication.  HTTPS Login unchecked.  Added the pfsense IP at Allowed IP Addresses.

                            The Win7 computer access internet as if CP is turn off, is not blocked.

                                OK.  I though that there was a posible work around.

                                Not being the case, for my needs CP in pfsense is not a viable solution.  In my case as many others, DHCP and primary DNS must be kept on the Windows Domain Controller.

                                  DHCP Relay (and keeping DNS to DC) is not an option?

                                    How will I use DHCP Relay?

                                    My DHCP (DC/DNS) server IP is 192.168.56.10 (static, 255.255.255.0)
                                    My pfsense IP is 192.168.56.1 (static, 255.255.255.0) in LAN side, WAN is DHCP assign from cable modem. I do not have any other interface.

                                      It happens that I have a client that has a Win Server with AD/DNS but without DHCP because it has a Wifi Router that is doing the DHCP Server role.

                                      So I can turn on DHCP on pfsense and configure the router to use the pfsense's dhcp.

                                      How should I configure the pfsense dhcp to register addresses in the AD/DNS?

                                      Once I get this dhcp running I can turn on CP in pfsense

                                        No idea why you wouldn't just use Windows DHCP in that case.

                                        DO NOT set a source address/port in a port forward or firewall rule unless you KNOW you need it!

                                          I tried Captive Portal with DHCP in the AD, but it did not work.  Also in this thread was directed to the note referred by Gertjan on: June 21, 2016, 04:55:46 am , implying that DHCP must be done by pfsense as CP works correctly.

                                          It was suggested to use DHCP relay but I do not how could I use that for this situation.

                                            OH! Still does not work.

                                            I turn dhcp off in the AD server and turn on dhcp on pfsense.  The PC aquired the IP succesfully as can be seen on the dhcp leases in pfsense.

                                            But chrome does not call the CP login page.
