hi, what do you mean by external DNS, is it your ISP DNS?

hi, try to configure your external DNS in forwarder, you can get it in your internal DNS server-properties select forwarder from tabs.

Hello, your question is not clear for me. Do you tlkl about internet access problems on domain machines when removing the public DNS servers from the NIC? Then FORWARDERS on the DNS server properties in the DNS mangement console MUST be set for the ISPs DNS server. If you have your own webpage running that is accessible from the internet BUT not internal then create an A record name "www" without the quotes in the domain DNS zone and use the ip address from the webserver. An unedited ipconfig /all from the DC/DNS servers and a client with problems will help us to verify the settings.Best regards Meinolf Weber MVP, MCP, MCTS Microsoft MVP - Directory Services My Blog: http://msmvps.com/blogs/mweber/ Disclaimer: This posting is provided AS IS with no warranties or guarantees and confers no rights.
