We just released an update to the IIS7 Management Pack for System Center Operations Manager 2007 that adds support for monitoring Windows Server 2008 SP2 and Windows Server 2008 R2:
This management pack provides an early warning to administrators on issues that could affect services so that administrators can investigate and take corrective action, if necessary. The management pack helps to simplify the administrative environment by providing a single console for the administrator to perform a number of useful management tasks. To help troubleshoot common issues, the management pack contains helpful product knowledge and a way to extend this knowledge through adding your own company or organization knowledge related to an issue.
To get all the details and download the management pack see http://www.microsoft.com/downloads/details.aspx?FamilyID=d351bca8-182b-4223-8c9e-627e184ba02b&displaylang=en
