Unfortuantely, this isn't possible. Each Active Directory Domain
controller registers itself with a (same as parent) record in the
domain for which it is a DC. This is one of the methods clients use
to locate a domain controller. A specific host record will need to
be added for your Exchange server.

Actually Mike, this default behavior can be altered. Have done it countless
times with clients and demos with no problesm whatsoever. It's referecened

Nadim, here's the *specific* instructions on how to do this:
===============================
This is good especially if you have a Split Horizon environment where the
internal and external domain names are the same and the users need to get to
their external name by
http://theirdomain.com but their DC/DNS server
responds and not the actual external website.
This one is done on the netlogon service parameters in the registry. This
will stop netlogon registering that blank FQDN with the internal private IP.
Here's how to clean that up. In summary, what you're going to do is
first you stop the netlogon service from registering that "Blank Domain
FQDN"
IP address. Those IPs are actually called the LdapIPAddress.
Then you create your own Blank Domain FQDN IP
(your own LdapIPAddress) that cooresponds to your actual external website.
Here you go:
==========================================
Disabling the Same As Parent LdapIpAddress blank FQDN and auto Publishing a
Blank Domain FQDN IP:
[Taken from
http://support.microsoft.com/?id=295328]
To disable only the registration of the local IP addresses, set the
following registry value, then reboot the machine for it to take effect:
1) Add the
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Netlogon\Parameters
Registry value: DnsAvoidRegisterRecords
Data type: REG_MULTI_SZ
Value: LdapIpAddress
2) Do this on all DCs and restart netlogon or restart machine.
This will prevent the DC from adding the domain A records from netlogon.
And you can add multiple Blank Domain A records as you need.
After you set this value, you must manually create your publicly available
IP addresses for your domain to appear as:
Same as parent folder Host "publicIP"
To do so, rt-click your domain name, new Host, leave the name field blank,
enter the actual external IP address. In your case it's the Exchange server,
or
whatever record you want it to be.
You're done.
====================================
Cheers!
