Strange DNS/hosts file lookup problem
Posted on 2006-06-19
We need to support third party server.
The server has a locally installed secure certificate that is mapped to an external ip address via hosts file so that external.name.local should resolve to the ip address and hence match the secure certificate (dont ask why they have done it like this, must be a security feature :)
The trouble is that on an external line using only the ISPs DNS server it works fine, on our internal network I get the feeling that it is conflicting with the internal DNS server, when tried we get the error message,
503 Service Unavailable
Failed to resolve the name of server m3gate.maytas.local to connect
We are using a proxy server but it is not set to cache/bypass https which the site is..
Annyone any ideas?
Any info much appreciated.
