We have a Windows 2003 server hosting box. It runs DNS for the domains we host and needs to do lookups to find remote domain IPs. This means the server can be used as a DNS by anyone who wants to access it.
How can I lock it down so only the local machine can do the wildcard lookup, and remote users only access the DNS of the domains we're hosting without stopping the server side apps being able to access what ever it needs to?
Thanks,
