how do I get two active directories to coexist

I have one domain that can not go to the web because I named it gary.local.
but I want to have a domain that can go to the web to run an exchange server: gary.com
they will be on two different 2008 servers.

will they play nice with each other?
is there anyway to make them share users and computers?

You don't need two Active Directory domains, just two DNS domains.  The current DNS domain (.local) is fine for your internal stuff.  You can buy and external domain name (I expect gary.com is taken), find a host for it (or host it yourself), have your internal DNS server(s) forward to it for external resolution, and set up your mail server to use it.

No need man
You can install exchange and configure your exchange with any domain you wants
The only thing you will do is to ask your ISP to configure mx record for your exchange with the domain name you will chose
And you need to publish your internal exchange ip to that public ip which given by your ISP

The names are just examples.
the server I am trying to install on is part of the gary.local, but exchange says it can find no active directory that this computer is a member of.  Even though when you look at the Active Directory it is there.
do I have to move it from gary.local to gary.com.
these are the errors I get.
1. setup encountered a problem while validating the state of active directory.  could not find active directory site to which this server belongs.
2.This computer does not belong to a valid active directory.  Check the site and subnet definition.

warning this computer requires microssot office 2010 filter packs. (I am assuming because I have 2003 outlook on the system)

okay let me explain something else. (agian names and ip are just examples of real ones)

the gary.com has an mx record of say 64.91.117.34 which I own. and an A record that points to a different ip address say 65.91.34.112 which would be a web site someone has set up for me.

my internal network is on 192.168.40.0 to 192.168.50.0 depending on office.  everything goes through a little firewall box for may network.  If I come around the firewall box and have the exchange server on a nic that has 64.91.117.34 then it is out side of my ip scheme and no one can find it.  At least I don't think I can put a mail.gary.com mx record on my AD with that ip and everyone can then have mail.gary.com in there outlook can  they????

I already tried two nics one on 64.91.117.34 and one on 192.168.40.225 but all I get is grief from my 2008 server that I can't have to nics on different networks.  I had thought that I could point the internal mx record to the 192.168.40.225 and the external to 64.91.117.34.

The people that sold me the firewall said they can set up a second ip and build firewall rules that let 64.91.117.34 in and send all traffic to 192.168.40.225.  Will this work????  I have one blackberry that needs to get email, will it do it if the internal exchange is not on a public ip?

read all of the articles posted above and unless I'm being dense they don't cover my problem.

Your pulic IP is set to the extenal interface of your Internet device, you dont need to add this to your internal device you just forward port 25 (for SMTP) and port 443 (for SSL) to your internal IP address of your server.

Yes.  Keep your Exchange server inside your firewall.  Set up your firewall to forward SMTP, POP, IMAP and HTTP/HTTPS traffic aimed at your public MX IP address (64.91.117.34) to the internal IP address of your Exchange server (192.168.40.225).  This is referred to as NAT.

External users (the public, including your Blackberry) will see your Exchange server at 64.91.117.34.  Internal users will see your Exchange server at 192.168.40.225.

okay I made the exchange mail.gary.com  on one 2008 server)and my network gary.local on another 2008 server
so as near as I can tell it doesn't know what DC to use, now would it be talking about the local dc or the gary dc.

when I do NLTest.ext /DsGetSite this is the return:
getting dc name failed: status = 1919 0x77f  error_no_sitename

log into the the server that I want to install the exchange to.  I get the following messages:


when I try to connect to the connections in the error messages there is nothing there on the microsoft site. so they point you to a forum that doesn't help.
