Internal and External DNS on Windows Server 2003

[Curiosityx]

Greetings, we have a Windows domain and exchange server running on SBS2003 with internal DNS resolution for the prefix domain.local.

We also have a DMZ that hosts our website, ftp and meetingplace server using the prefix domain.co.uk, each server uses an RC1918 address and has static nat entries listed on the firewall for external connectivity.

Instead of fiddling with the firewall can anyone say whether adding the "domain.co.uk" domain to the internal DNS server would cause problems with exchange. I would like to resolve "www" "Ftp" and "meetingplace" on said domain pointing to there internal ip addreses so that uses can access them internally.

We do have a third party hosting the domain as well which we would keep this is just for internal resolution only.

Regards

If I've read this right you want to use a DNS zone internally which is already used externally to resolve names?

If the above is right then no, it won't bother Exchange. SMTP domains are totally seperate from DNS zones held on your DNS server(s).

Create a new DNS zone (AD integrated if you've more than one DC, simplest to setup) for domain.co.uk and add A records mapping to the appropriate IP's. e.g add a WWW 'A' record in domain.co.uk pointing to whatever IP address you want the internal clients to hit on your internal DNS server.

I'm often not the best at explaining things, happy to go into more detail if it will help.

No thats great thank you, ill make the changes now.
