We recently migrated our public web site to a hosted web site, that is both accessible to internal users via a VPN connection to our hosting partner as well as from the public internet.
Prior to doing this, internal users could connect to the short URL for the site using http://domain.com/subpage versus http://www.domain.com/subpage.
The public can access http://domain.com/subpage just fine, DNS is hosted by Nuestar and there is a wildcard that allows this.
Internally, our clients use AD DNS for resolution, and this ONLY WORKS FOR FIREFOX USERS.
IF an IE or Chrome client tries to connect to http://domain.com - that works, but http://domain.com/subpage does not. Firefox works for both situations.
I tried adding *.domain.com as both an A and CNAME record pointing to our internal IP and also to our public IP, but neither work.
It sounds like an issue with AD DNS but it's weird that it works with Firefox so I'm not sure if there is a client issue on top of that.
