Help with setup of Exchange server
Posted on 2004-09-10
OK, I have been battling for a while to get this configuration going but no luck.
I have our public domain (xyz.com.au) and our local domain xyz.local. xyz.local is an Active Directory domain, while xyz.com.au is a standard DNS domain.
DNS for xyz.com.au has an entry for mail.xyz.com.au that points to say 188.8.131.52 and DNS internally has mail.xyz.local that points to 192.168.1.252.
Our firewall routes ports 25, 110 and 80 from our mail servers external IP Address to our internal IP Address.
Now, internally, when I use Outlook and add a new mailbox, when I enter a server name of mail.xyz.com.au and a valid username all works fine, but server name gets changed to its internal server name mail.xyz.local. No problems...it works...Just somethiing I noticed.
Now, for the part that doesnt work. I have a number of laptop users, all who have Outlook 2003. I am trying to get RPC over HTTP working So I can use "Exchange over the Internet". The prolem I am having is that when I try to do a Check Name from External to the local network, ie from Home, I get an Internet Explorer Authentication Box from Realm mail.xyz.com.au. The authentication never passes and so I can never get it to work. I cant uses the previously working "Check Name" from on the local network as the server name changed to the internal server name.
Any ideas what is going wrong?
