Active Directory Rights Management Services
Active Directory Rights Management Services (AD RMS), included with Microsoft Windows Server 2008 R2, allows administrators or users to determine what access (open, read, modify, etc.) they give to other users in an organization. Access restrictions can improve security for email messages, internal websites, and documents.
To secure documents, Microsoft Office 2003 Professional (Word, Excel, PowerPoint, and Outlook), Microsoft Office 2007 Enterprise, Professional Plus, Ultimate, Microsoft Office 2010 Professional, or Professional Plus is required.
