I installed Smart Security last night on 2 computers, one laptop, and one desktop. The laptop works fine. The desktop won't let me browse the internet. Chrome returns an error that the DNS can't resolve the host name. Looking at the zone settings on both computers shows a difference in the DNS server field. The working computer has 2 IP addresses, the non-working computer only has one IP address, my router. The Edit option is grayed out for the DNS Server. How do I change the IP address for DNS? BTW, When I turn off the firewall, everything works fine.
