Lab Testing for my Microsoft Exchange and Active Directory studies


Need your idea on how can i implement a Lab Testing for my study on Microsoft Exchange 2003.

What i really want is to implement a setup that is roughly the same scenario with 2 companies that are exchanging mails.

I want to use Virtual PC 2007 on this, is it possible? if yes, please advise how can i implement it.

Please help. Thank you.

you need to setup 2 server.

                                                                first server.                                      (second server)
install windows 2003.  IP address                                
 and promoted to DC.                                   call A.local (another one call b.local)
then install exchange 2003                                               used (another call
create and point to (both server)
create and point to  (both server)

thiis is a very rough idae how you gonna setup...
it is not a  microsoft exchange best pratice (you should not put DC and exchange in 1 server for example)

Hi Limjianan, Thanks for the responsed.

What i want in my simulation is, each companies should have different IP address convention (ie. companyA is, companyB is

my plan is to create atleast 5 virtual machines
1 RRAS (lan routing)- Router for both domains
2 AD/ Exchange- CompanyA.local/ CompanyB.local
2 XP OS/ outlook- xpA.companyA.local/ xpB.companyB.local

my objective is, johnsmith@companyA.local can send and receive mails from user in CompanyB.local and VICE VERSA.

guys, if any of you have an idea in mind on how to setup this please share with me. Thanks. ill appreciate it.
This will be a great help for me.


* Pretty simple one.

* Company One: ASIA.COM

*Machine 1:
OS - Windows 2k3 SP1
Name -
Roles: DC, DNS, Exchange
Exchange Org name: Asia

* Company Two: EU.COM

* Machine 2:
OS - Windows 2k3 SP1
Name -
Roles: DC, DNS, Exchange
Exchange Org Name: EU

* Router (acting as ISP)

* Machine 3:
OS - Windows 2k3 SP1
Name - Router (This machine would be in a WORKGROUP and would have 2 NICs)
Roles: DNS

* Enable LAN routing in this using RRAS

* Now the first Machine 1 would have its DNS server pointing to itself and in the DNS configuration would have the IP of the Router as forwarder ( Also it would have its gateway entry as

* Then the second Machine 2 would have its DNS server pointing to itself and in the DNS configuration would have the IP of the Router as forwarder ( Also it would have its gateway entry as

* Finally the Router would have 2 forward lookup zones in it; one as and other as Both these zones would have their respective Exchange servers host (A) and Mail Exchanger (MX) records {in this case the host names and ips or the respective DCs since they host exchange too)

* And at last you have 2 XP machines as clients, each belonging to their respective domains and can have a static ip  address respectively like and and would have their respective DNS server entries and Gateways

Hope this helps (^_^)
Creating Active Directory Users from a Text File

If your organization has a need to mass-create AD user accounts, watch this video to see how its done without the need for scripting or other unnecessary complexities.

Hi Rudram, great! thanks for this info.

in your first procedure=> * Enable LAN routing in this using RRAS
is there any configuration in RRAS LAN routing that i need to do for me to establish connection between companies- ASIA.COM, EU.COM??

Awaiting for your response.

* No extra configuration needed. What we are doing here is, we are actuall establishing a connectivity between the 2 NICs of the machine "ROUTER".

* This is because both those NICs, even though they are of the same machine, have been given IP addresses of 2 entirely different networks.

* So what we achieve here is when the DC from will try to access or query the DNS server for, the query would propogate from DC to the Router (which is our acting ISP now) and from there using the 2nd NIC of ROUTER it will propogate to the DC of Thereby establishing the route for the message to flow.

* About RRAS, open the Routing and Remote Access console on the ROUTER.

* In that console, right click the server name and say "Enable and Configure Routing and Remote Access"

* In the following wizard, say next and select the "Custom Configuration" option and say next.

* Finally select the LAN Routing option and say finish.

* There you go with both the NICs on  the ROUTER machine connected and routing enabled between them.

* Rest follow the earlier post on how to setup the companies considering  the fact that you might be aware of how to create a new domain and configure DNS and stuff.

Good Luck (^_^)
