We have a Windows 2000 Small Business Server running a single NIC internet access solution. It uses the domain internally of say 'mydomain.co.uk' with a local IP range of 192.168.0.xxx. Everything works fine unless you try and access the domain on the internet as say'http://www.mydomain.co.uk'
i.e. the internal and external domains are the same. The external pages are unavailable with the error 'This Page Cannot be Displayed' etc... If you PING the 'www.mydomain.co.uk'
the error 'unknown host' comes up. The Internet domain is separately hosted and has a pingable external IP address.
This used to work with a dual NIC solution but VPN through a hardware firewall was required and this necessitated the shift to a single NIC solution.
I'm sure it's a DNS entry (or entries) but an entry for 'www' in the forward? lookup zone with the correct IP then allows PING to work but browsing the URL fails as before and the IP by itself gives the ISA Firewall login!
Can anyone help please?
