Configuring Windows 2008 R2 AD Multi Site with Routing and Route Access Configuration for the lab


If you are IT guys and labs are is like your best friend. You can play with your Best friend any time but not with production boxes. Most of the companies are getting global Day by Day and it is spread across multiple location. If you wanted to simulate and test any application like Exchange and AD across the site then you need build the lab for the same. Here I am trying to explain you How to configure a domains with two sites with Routing and Remote Access servers installed as router to route the traffic between two sites on a Single Windows 2008 R2 Hyper V Server

Preparing the Network Settings

1. Configure Hyper-V Virtual Network Manager to add new "Internal" Network.


2. Configure all the Servers built on Hyper V to use this network Adapter Internal

Servers Installed and Configuration Details

Server Name






Windows 2008 R2




Windows 2008 R2




Windows 2008 R2




Configuration of Window 2008 As Router

  1. Login Server name "Router" and make sure that 2 NIC is configured with IP address and, without any default gateway and DNS servers. Below figure 2 has the detail configuration on one of the NIC which is having IP address Asite. Similarly configure NIC on BSite with the IPaddress


Figure 2. IP Address Configuration on the Server "Router "

2. With this NIC configuration you should be able to ping both ADC and BDC from the Server "Router". From ADC You should be able to ping IP address on the Router which is ping to ASite ( but not the IPaddress of NIC point to BSite( ADC should be not able ping to BDC. This is because Router is acting as a median between Asite and Bsite and currently Router Server is not configured to route the packets from Asite to Bsite and Vice Versa.

3. Now lets configure Server Router for routing the packets. login to Server Router Launch Server Role and select Network Policy and Access Services (Figure. 3) and click next


Figure 3. Adding Network Policy and Access Services

4. Select Routing and Remote Access Services (Figure 4) and click next and finish to install the same


Figure 4. Enabling Routing and Remote Access Services

5. Once we have Routing and Remove access Services Role installed on the Router, we should be able to see the role added in the Server Manager. Right click on Role Network Policy and Access Services and click Configure and Enable Routing and Remote Access to enable the same


Figure 5. Network Policy Access Role added in the Server manager and its available for configuration

6. On the welcome screen to configure routing and remote access server wizard click on Next.

7. In the configuration step click on Secure Connection between two private networks (Figure 6)and click Next. This is setting which helps to enable routing and click on Next


Figure 6. Enabling Routing Settings

8. You will be prompted for enabling demand dial connection(Figure 7) which we don’t need. Click on Next


Figure 7. Option for Demand Dial

9. Finally Click on Finish and this is complete the initializing of the new role

12. Once we have installed RIP Protocol we need to added the required Interface for protocol. Right Click on the RIP to install the Interface which is point to ASite and BSite


Figure 11. Configure Network Interface to the RIP Protocol

13. Keep all the default settings when you add the interface. Once we added both the interface we should be able to see the same on the console. Figure 12


Figure 12. Settings after adding both the Network Interface on the RIP protocol

14. Once we have this configuration in place then we should be able to send and remove packets between Asite and Bsite. This can be confirmed by pining All the IP address available on BSite from Asite (Figure 13) and Vice versa


Figure 13. Pining BSite servers from Asite Servers

15. Once we have this configuration on Place we have communication established between both the sites. Now Lets Install and configure Domain Controller and Configure AD Sites for the AD Replication

16. Login to ADC | Start | Run | DCPROMO | OK to Promote ADC as domain Controller


Figure 14. Starting DC Promotion

17. Click Next on the Welcome Screen

20. Configure Forest Function Level and Domain Functional Level with required settings with Windows Server 2008 and click Next


Figure 18. Configure Domain Function level

21. Configure DNS Servers to install (Figure 19) and YES to continue


Figure 19. Installing DNS Server

22. Set the required path for the Active Directory Database , log and Sysvol. Recommended to keep it default and click on Next


Figure 20. Configuring AD Database, log and Sysvol location

23. Provide required AD restoration Password and click on Next to Install and Configure AD and DNS on the Server. Figure 21.


Figure 21. Installing Active Directory and DNS

24. Restart the Server once Installation is Finished

25. Now Lets configure AD Sites and Services

26. Login to ADC | START | RUN | dssite.msc | ok


Figure 22. Starting Active Directory Sites and Services

27. Expand AD sites and Services and Right click on Default-First-Site-Name to ASite


Figure 23. Reaming Default-First-Site-Name to ASite

28. Lets now Create a new Site With BSite. Right click on the Sites and click on New Site


Figure 24. Create New AD Sites – Bsite

29. Provide the New Site name Bsite and click on DefaultIPSiteLink and click on OK and Next to configure the same. Figure 25.


Figure 25. Creating new Site with DefaultIPsitelink Configuration

31. New we should be able to see the new Site created with the name Bsite


Figure 26. Console after New Site Creation with BSite

30. Once we have Sites in place lets configure subnets. To configure the same right click on Subnets and Select new Subnet Figure 27.


Figure 27. Creating new Subnets in Active directory users and computers

31. In our Current setup we have two subnets and Here we are trying to create a new subnet and associate Sites with the subnets

32. On the new Subnet enter the IP Subnet with Subnet mask and click on Asite and click ok


Figure 28. Configure Subnets with Asite

33. Configure the same for BSite with IP Subnet

44. Once we have BDC as domain controller in place we should be able to see new DC Server add on the AD Sites and Servers under Bsite


Figure 41. Ad Sites and Services after BDC installed

45. By Default Active Directory Sites are configured for replication, Any changes done on Asite will be replicated to Bsite. There will be delay in the replication. By default the replication time is configured for every 180 min. We can changed this to minimum replication for every 15 min.

46. Lets configure the replication settings between the sites to replicate every 15 min. Access Active directory sites and Sites

47. Expand until you reach Inter-Site Transports. Select IP and click on properties on the DefaultIPsitelink. Figure 42.

  1. To configure a router you don’t need to install Routing and Remote Access Services.

    You can simply Enable “IPEnableRouter” in “HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\Tcpip\Parameters” (keep in mind to reboot a server) or use IPv4Router.exe that i’ve built back in a days for myself. IPv4Router.exe coyld be downloaded from

    • Hi,

      Thanks for your post. I tried your configuration but I have some issues – some questions:

      Is router server is part of VM?
      What is the configuration of 2 NIC’s for this router server?

      thanks in advance.

      Best regads,

  4. Hey I’m a newbie in this hyperv world. I liked your article but just to set things straight for me. Your scenario has a physical server with two nics and there are 3 hyper view servers adc and bdc with a single nic and router with 2 nics. On the physical server we are not supposed to put any ip right whatever ip assignment we do is on hyperv servers only right? I tried to follow your post step by step but no luck because I’m not that confortable with hyperv. Pls help because your post is the only one which made some sense to me and I stuck.
