Exchange 2007 SP 3 System Requirements

Hi All,
Today we will be looking into the System Requirements for Installing Exchange 2007 SP 3 on Windows Server 2003 SP 2
Network and Directory Services
Schema Master: Should be running on Microsoft Windows Server 2003 SP 1 or Windows Server 2003 R2
Global Catalog: Each site which contains Exchange 2007 must have at least 1 GC
                1. W2K3 SP1 support exchange 2007 service notification
                2. W2K3 SP1 and later versions allow users to browse the address book in Microsoft OWA
                3. W2K3 SP1 and later version provide the ability to look up distribution list in more effective manner
Domain Controller: Must be W2K3 SP1 or Later
Domain Functional Level: Windows Server 2000 native at least
Forest Functional Level: Windows Server 2000 native at least and if you want to use adv features like cross forest free/busy information then Windows Server 2003

Prepare Topology

From Command Prompt: For ease we will use Enterprise Admin account for all operations.
You can access all help regarding prepare Topology using /Help:prepareTopology /PrepareLegacyExchangePermissions  this need to be run on Parent as well as child Domain controller if you are upgrading from Server 2003. If it’s a fresh install then it can be skipped. /PrepareSchema
Verify C:\documents and settings\user\Local Settings\Temp
Ldf.log file with all the new schema attributes added
Check rangeupper value on ms-Exch-Schema-version-pt using adsiedit. It should be 14625 for E2K7 SP3. /PrepareAD Preparing Active Directory for Exchange 2007
If this is a new Setup then You need to specify Organisation Name other wise the the above setup will fail /PrepareAD /OrganizationName:Name
Verify if the Preparation was successful. Check C:\ExchangeSetupLogs\ExchangeSetup.Log file
Check security groups under new OU, Microsoft Exchange Security Groups would be created
1. Exchange Organisation Administrator
2. Exchange Receipient Administrator
3. Exchange Public Folder Administrator
4. Exchange Servers
5. Exchange Trusted Sub System
6. Exchange view-only Administrator
7. ExchangeLegacyInterop /PrepareDomain or /PrepareAllDomain
Verify: This setup will create Exchange Install Domain Servers group under Microsoft Exchange System Object and make this group a member of Exchange Server group.
It also updates the objectVersion of Microsoft Exchange System Object ou.
The objectVersion for SP 3 is 11221

Another thing we can check is that Exchange Servers universal security group will be added to the security of "Manage Audit and Security log" under Default Domain Controller Policy.

Windows Installer 4.5
.Net Frame Work 2.0
IIS 6.0
PowerShell v2.0 [I have used v2.0 for SP3 however for earlier Exchange 2007 PS v1.0 is used]
Hotfixes [These hotfix will be listed during the setup, otherwise these can be predownloaded and installed]
