        Re: DNS error

        When I run DNSLint /d it displays 2 DNS (ISP) servers for the domain as authoriative. Is this correct or should it display my internal DNS servers?

          Re: DNS error

          Normally your internal servers should be authoritative for the AD domain, with the ISPs ones for your public domain
