If the page does not load, you may need to delete any default/existing DNS Server settings on the router/computers, and then try accessing Comcast's activation page again. If you have trouble activating online and no registration page appears after following the instructions above, you may need to call Comcast at 855-652-3446 to register your. Check the comcast/xfiinty router DHCP settings and see which servers it is handing our to your clients on the network. Or, you can disable the DHCP server on the comcast/xfinity router and setup a DHCP server on the domain controller. The domain controller will still hand out IP.
