Installing Exchange 2010 Prerequisites on Server 2008 R2
Posted by Ståle Hansen on 30/10/2009
Update 08.12.11: Exchange Server 2010 SP2 was released and require an additional prerequisite which is IIS 6 WMI Compatibility feature (Web-WMI). This article and PowerShell Script was updated accordingly in all options containing the CAS role.
Before you begin, prepare your environment
- Make sure that the functional level of your forest is at least Windows Server 2003
- Also make sure that the Schema Master is running Windows Server 2003 with Service Pack 1 or later
- If Database Availability Groups (DAG) is going to be used install Server 2008 R2 Enterprise Edition
- Exchange 2010 Standard Edition supports DAG with up to 5 databases
- Exchange 2010 Enterprise Edition supports up to 100 databases per server
- You can install all server roles on the same server when using DAG
- But then you need a hardware load balancer for redundant CAS and HUB due to a Windows limitation preventing you from using Windows NLB and Clustering Services on the same Windows box
- Two node DAG requires a witness that is not on a server within the DAG
- Exchange 2010 automatically takes care of FSW creation; though you do have to specify the location of the FSW
- It is recommended to specify the FSW to be created on a Hub Transport Server
- Alternatively, you can put the witness on a non-Exchange Server after some prerequisites have been completed
- You can follow these steps to get your member server to act as FSW
- add the “Exchange Trusted Subsystem” group to our Local Administrators Group on that member server
- On servers that will host the Hub Transport or Mailbox server role, install the Microsoft Filter Pack. For details, see 2007 Office System Converter: Microsoft Filter Pack (this allows office attachments content to be searched and indexed)
- Set Pagefile size, RAM + 10MB (for systems with 8 GB of RAM or less, set pagefile to RAM * 1,5)
- Disable IPv6 by using this guide: http://support.microsoft.com/kb/929852
- Run Windows Update untill all updates are installed
Install the Windows Server 2008 R2 operating system prerequisites
- Open powershell and run the following command
- Import-Module ServerManager
- For a server that will have the typical installation of Client Access, Hub Transport, and the Mailboxroles:
- Add-WindowsFeature NET-Framework,RSAT-ADDS,Web-Server,Web-Basic-Auth,Web-Windows-Auth,Web-Metabase,Web-Net-Ext,Web-Lgcy-Mgmt-Console,WAS-Process-Model,RSAT-Web-Server,Web-ISAPI-Ext,Web-Digest-Auth,Web-Dyn-Compression,NET-HTTP-Activation,RPC-Over-HTTP-Proxy,Web-WMI -Restart
- For a server that will host the Client Access and Hub Transportserver roles:
- Add-WindowsFeature NET-Framework,RSAT-ADDS,Web-Server,Web-Basic-Auth,Web-Windows-Auth,Web-Metabase,Web-Net-Ext,Web-Lgcy-Mgmt-Console,WAS-Process-Model,RSAT-Web-Server,Web-ISAPI-Ext,Web-Digest-Auth,Web-Dyn-Compression,NET-HTTP-Activation,RPC-Over-HTTP-Proxy,Web-WMI -Restart
- For a server that will host only the Mailboxrole:
- Add-WindowsFeature NET-Framework,RSAT-ADDS,Web-Server,Web-Basic-Auth,Web-Windows-Auth,Web-Metabase,Web-Net-Ext,Web-Lgcy-Mgmt-Console,WAS-Process-Model,RSAT-Web-Server -Restart
- For a server that will host only the Unified Messagingrole:
- Add-WindowsFeature NET-Framework,RSAT-ADDS,Web-Server,Web-Basic-Auth,Web-Windows-Auth,Web-Metabase,Web-Net-Ext,Web-Lgcy-Mgmt-Console,WAS-Process-Model,RSAT-Web-Server,Desktop-Experience -Restart
- For a server that will host the Edge Transportrole:
- Add-WindowsFeature NET-Framework,RSAT-ADDS,ADLDS -Restart
- After the system has restarted, configure the Net.Tcp Port Sharing Service for Automatic startupby running the following command:
- Set-Service NetTcpPortSharing -StartupType Automatic
PowerShell Script: MVP Pat Richard has created a script to automate the process of installing the prerequisites: http://msunified.net/exchange-downloads/script-exchange2010prereqs-ps1/
NOTE: You can also install the above features using xml scripts found in a scripts catalogue on the Exchange media. You still need to manually configure Net.Tcp Port Sharing Service for Automatic startup though. There is one script for every role.

The link to disable IPv6 is dead (http://blogs.technet.com/fixit4me/archive/2009/01/21/disable-ipv6-fix-it-live.aspx). It doesn’t work for 2008 R2 (see there).

Thanks for letting me know. In Server 2008 R2 you need to do it manually using regedit. Updated with this link http://support.microsoft.com/kb/929852

For those that just cut and paste commands without reading them, you should probably point out that the “-Restart” is optional on the command line and not required there (although a restart is required prior to being able to use any of things that ServerManager installs). I’m never impressed when a server automatically reboots while I’m installing software on it. Removing the -Restart allows you to manually restart the server after PowerShell is done.

Hello Raja, thanks for asking on my blog :) For a detailed guide on how to deploy Exchange 2010 I recommend reading through the Microsoft Exchange Server 2010 Install Guide Templates. The download link can be found under http://msunified.net/exchange-downloads/ under the deployment section. Good luck :)

Hey Ståle
Great post
btw you should update the filterpack to the 2010 version and include a link to the SP1 for it as well.

Hi Ståle,
I used your Powershell script to recover an Exchange server 2010 SP2 with a typical configuration and it asked for ASP.net and ISAPI filters to be included. I thought you might like to know
Thanks for this.
