Question : host names not resolve from command prompt

I have an issue on my network that when I ping from the command prompt say google.com it is always not resolved!!! or any other host name

I know that something I have to do on our DNS server. but I am dont have experience configuring DNS server.

our DNS server is a windows server 2003.

where I should check if the public DNS is configured or what I have to look at to fix resolving internet host names from the command prompt?

Answer : host names not resolve from command prompt

Hello

your internal DNS server need to be able to resolve external names.

For that in "DNS Manager", right-click on your server name and choose "properties".
Two way to achieve that :
1) if you know the dns server of your provider (lets say "dns.provider.com"), then go on the "forwarders" tab, click on edit and add this name (or ip). You could also input there a public dns (google for it, for example you can use 8.8.8.8).
2) make your server resolve the names by itself in having nothing in that "forwarders" but making sure the "Use root hints if no forwarders are available" is checked (the "Root hints" tab is filled-in with the root-servers by default, don't change it !)

If you still have problems, make sure in the "Advanced" tab that "Disable recursion" is UNchecked, and lastly that your server is able to access the internet on port TCP/53 and UDP/53 (do you have any firewall with outbound rules in place ?)

Best regards,
