For example, who can read a document and who can print it. This is done without IT staff making any changes to NTFS file permission. AD RMS works with Windows Vista, Windows 7, and Windows Server 2008. You can also utilize AD RMS with Windows XP, 2000, 2003. To do this, you wil need to download a separate version from Microsoft.
