Hi, hopefully someone can help with this.
We have a few domains all hosted externally on the same ip. If i browse to any of them externally everything is fine, if i try to browse to them from the LAN only the parent domain resolves, all the others are blank. ( i can resolve www.school.com
but not www.child.school.com
Things are a little mixed up as we have our own exchange server which uses the same domain name as our externally hosted website, lets call it for this purpose school.com. To overcome any mail issues ect we have a lookup zone called school.com this zone holds 'A records' for school.com which it resolves to the hosting IP, and webmail.school.com which points to our exchange servers, and www which resolves to the externally hosted website '18.104.22.168' for example.
When i try to add either a 'A record' or a CNAME to this zone it makes no difference. For example a CNAME which points child.school.com to school.com. The parent will resolve on the internal DNS fine but the child won't
Am i barking up the wrong tree here? Any help would be greatly appreciated.
