The Microsoft Exchange Best Practices Analyzer determines whether Exchange Server is installed on a Windows Server 2008-based computer. The Analyzer tool will then verify that the hotfix that is described in Knowledge Base article 974646 has been installed.

This hotfix resolves an issue in which a computer that is running Windows Server 2008 SP2 or Windows Vista SP2 stops responding when an application uses the NTFS sparse files. The Microsoft Search service (MSsearch) that is included with Microsoft Exchange Server 2010 uses sparse files. Therefore, this hotfix must be installed to avoid the issue.

Note

This hotfix applies only to Windows Server 2008. Windows Server 2008 R2 contains this fix.

For more information about the hotfix, see Microsoft Knowledge Base article 974646, A computer that is running Windows Server 2008 SP2 or Windows Vista SP2 stops responding when an application uses the NTFS sparse files.
