Exchange 2010 SP2: IIS 6 WMI Compatibility is required

When you install the Service Pack 2 of Exchange 2010, you may encounter this error ‘The IIS 6 WMI Compatibility component is required’. In fact, when you upgrade your client access server role you  have to add this component. It’s a new prerequisites for CAS role.

Because I’m a PowerShell fun, this Cmdlet will solve the issue :

• Open Windows PowerShell
• Type : Import-Module ServerManager
• Type : Add-WindowsFeature Web-WMI

NB: You only encounter this error when you upgrade from Ex2010 SP1 to SP2. But, when you install Exchange 2010 SP2 for the first time in your organization, you only check the box ‘Automatically install Windows Server roles and features required for Exchange’ and Exchange 2010 install all prerequisites for you.
