So do you believe that these guys using another namespace made them not be
able to use RPC over HTTPS. I am also planning on having this service
implemented to complement on the OWA SSL service. These are the service I
fear might not work if I used a different namespace. Can anyone clarify.

Yeah don't use the .local as one of my clients did and now their RPC over
HTTP is broken for good.

So listen to what Steve and John are saying and you will be in good hands.

 DO NOT USE ".local" AS THE TLD.

That is not a valid private use TLD:

John Savill's FAQ for Windows  

A. Companies often use a .local or .pvt TLD to name an AD tree. However, as
I explain shortly, it's better to use a standard naming method--for example,
create a name by using a subdomain of your company's DNS address space
(e.g., if your company's DNS domain is, you could name your AD
tree When you use this method, though, you must remember
that the DNS information for the AD tree is hosted on internal DNS servers,
not on your external DNS servers. This means that external users can't see
information about your internal infrastructure because external users can
access only the external DNS server, which has no information about your
internal infrastructure.
Alternatively, if you want to create a second-level name for your AD domain,
reserve another name--for example, don't set your AD domain
to the same name as your external name, to avoid causing confusion in name

If you're determined to use a nonstandard TLD in your domain name, avoid the
use of .local or .pvt because they aren't reserved. Instead, use one of
these reserved top-level domains:

You can find more information about these names in Internet Engineering Task
Force (IETF) Request for Comments (RFC) 2606. Remember, if you use these
nonstandard DNS names, you can't obtain certificates from a third-party
Certificate Authority (CA), which might cause problems for your

By the way, in using Windows Server 2003 AD, you can setup your domain as
internal.example.moc and in DNS point the root domain example.moc at the
external DNS server. That way, your internal DNS server will be responsible
for internal.example.moc and all other example.moc queries will be sent to
the configured external server.
