Algumas notas sobre o Exchange Server 2007 SP2

O tão aguardado Exchange Server 2007 Service Pack 2 está finalmente disponível para download. São muitas as novidades, mas gostaria de destacar 2 delas:

  • Suporte ao Exchange Server 2010: o SP2 é um pré-requisito à instalação do Exchange Server 2010 numa organização já existente de Exchange Server 2007.
  • Suporte ao Windows Server 2008 Backup: finalmente é possível efectuar cópias de segurança (VSS) ao Exchange Server 2007, utilizando a ferramenta de backup que acompanha o Windows Server 2008.

Aqui fica uma lista com as principais novidades do Exchange Server 2007 SP2, retirada do blog You Had Me At EHLO:

  • Enhanced Auditing - New Exchange auditing events and audit log repository enable Exchange administrators to more easily audit the activities occurring on their Exchange servers. It allows the right balance of granularity, performance, and easy access to audited events via a dedicated audit log repository. This simplifies the auditing process and makes review of audited events easier by segregating audited events in a dedicated location.
  • Exchange Volume Snapshot Backup Functionality - A new backup plug-in has been added to the product that will enable customers to create Exchange backups when a backup is invoked through the Windows Server 2008 Backup tool. Exchange Server 2007 didn't have this capability on Windows Server 2008 and additional solutions were required to perform this task.
  • Dynamic Active Directory Schema Update and Validation - The dynamic AD schema update and validation feature allows for future schema updates to be dynamic deployed as well as proactively preventing conflicts whenever a new property is added to the AD schema. Once this capability is deployed it will enable easier management of future schema updates and will prevent support issues when adding properties that don't exist in the AD schema.
  • Public Folder Quota Management - SP2 enables a consistent way to manage quotas by improving the current PowerShell cmdlets to perform quota management tasks.
  • Centralized Organizational Settings - SP2 introduces new PowerShell option that enable centralized management of many of the Exchange organization settings.
  • Named Properties cmdlets - SP2 enables Exchange administrators to monitor their named property usage per database.
  • New User Interface for Managing Diagnostic Logging- SP2 enables Exchange administrators to easily configure and manage diagnostic logging from within the Exchange Management Console.

Antes de instalar o Exchange Server 2007 SP2 aconselho vivamente a leitura das release notes.
Aqui ficam algumas notas pessoais resultantes da minha experiência de instalação:

  • O Windows Installer version 4.5 é um pré-requisito para a instalação do Exchange 2007 SP2 (o Windows Server 2008 SP2 inclui o Windows Installer 4.5). Depois da instalação do Windows Installer 4.5, é necessário reiniciar o servidor.
  • O Setup Wizard valida se o Windows Installer 4.5 está ou não instalado. Em caso negativo, o seguinte erro aparecerá: 
    e2k7sp2-windows-installer-4.5
  • Como ainda estava a utilizar o Windows 2008 SP1, decidi instalar o SP2. Depois do setup do Windows 2008 SP2 ter terminado, lancei a instalação do Exchange SP2. Foi com alguma surpresa que constatei que mais um reboot era necessário: 
    e2k7sp2-02
  • As “release notes” mencionam que o schema da AD deverá ser previamente preparado em 2 ocasiões:
        a) num in-place upgrade da versão beta do Exchange 2007 SP2
        b) na 1ª instalação do Exchange 2007 SP2 numa organização 
    No meu caso (cenário b), quando instalei o SP2 pela 1ª vez, o assistente de instalação fez todo o trabalho por mim, conforme se pode comprovar nas seguintes figuras: 
    e2k7sp2-04
    e2k7sp2-05
  • Aqui fica um screenshot do meu servidor com o SP2, a versão é agora a 8.2 (Build 176.2). Atenção que eu não segui a ordem de instalação recomendada: CAS > UM > Hub > Edge > Mailbox!
    e2k7sp2-06

Recursos Técnicos de certificados SAN

Embora os certificados SAN não sejam uma tecnologia propriamente recente, não posso deixar de pensar que os lançamentos do Exchange Server 2007 e do Office Communications Server 2007 trouxeram este tipo de certificados para as luzes da ribalta.

Como algumas pessoas ainda encaram os certificados SAN como bichos de sete cabeças, a comunidade técnica está permanentemente a publicar novos documentos e a desenvolver ferramentas bastante úteis que permitem simplificar as tarefas de criação e gestão deste tipo de certificados.

Recentemente, enquanto lia os blogs Pro-Exchange e TelnetPORT25, deparei-me com estes 2 fantásticos recursos técnicos sobre o tema que gostaria agora de partilhar com toda a gente:

  • The Shortcut Guide to Subject Alternative Name Certificates - The Shortcut Guide to Subject Alternative Name Certificates provides information about SAN certificates to show how they can be used in a variety of technologies. These special certificates allow multiple hosts to use the same certificate, avoiding the costs of obtaining, deploying, and managing multiple nearly-identical certificates. This guide will explore what SAN certificates are, how they work, and how they can help you deploy server farms more efficiently. You may even discover that you already have SAN certificates available that can be put to good use with no additional expense!
  • Exchange 2007 CSR Portable SAN Generation Tool - For many of us, we are just looking for a simple means to create an SSL certificate for our Client Access Servers which the DigiCert tool certainly offers, however – if like me you find (or found) yourself in the position where you have no direct access to the Internet from the Client Access Server (either for security reasons, or you are working on a machine with no web connection) you will have to remember the PS1 command syntax to generate the CSR. For situations like the above I decided to write the Exchange 2007 SAN CSR Generator which is a small Application based around the .NET 2.0 Framework which fits quite nicely on a USB pen or other media that you might use during the course of your Exchange endeavours.
