Introduction
Exchange Server 2010 SP2 is a recommended update for Exchange Server 2010. It comes not only with bug fixes, but with new features as well. With it, comes new pre-requisites if you are installing/updating Client Access Server (CAS) role. In this article, I will be showing you the new prerequisites and then start with installing SP2.
In my lab, I have a typical Exchange Server installation. A Typical installation consist of the Client Access , Hub Transport and Mailbox Server roles, along with the Exchange Management Console.
Service Pack 2 has a new prerequisites for the Client Access Role. You will need to install the following components on the server that is running CAS role :
-
ISAPI Filters – Web-ISAPI-Filter
-
IIS 6 WMI Compatibility – Web-WMI
-
ASP.Net – Web-Asp-Net
We will start first with running PowerShell commands to install the prerequisites and then download and install SP2.
Note: Make sure the user you are going to login with to install SP2 has the appropriate permission, as SP2 will update your Active Directory Schema. I will be using the same account which was used to install Exchange Server, and this user has the required permissions : Domain Admin, Enterprise Admin and Schema Admin.
1. launch PowerShell as Administrator
2. Type :Â Import-Module ServerManagerÂ
3. Paste the following in PowerShell to install the required features for SP2:
