When running ExBPA against a Windows 2008 cluster (either CCR or SCC) the following best practices may be flagged:
These rules only apply to Windows 2003 clusters and the recommendations should not be followed for Exchange 2007 / Windows 2008 clusters.
This is scheduled to be corrected in a future ExBPA rules update.
