Excluding Windows Versions
Applies To: Windows Server 2003, Windows Server 2003 R2, Windows Server 2003 with SP1, Windows Server 2003 with SP2
The Microsoft® Windows® Rights Management Services (RMS) 1.0 client is supported on computers that are running either Microsoft Windows 98 Second Edition or Windows Millennium Edition; however, these operating systems do not support NTLM authentication. For this reason, you might want to prevent users from consuming rights-protected content from a computer that is running one of these operating systems and require that they use versions of Windows later than Windows Millennium Edition for increased security of your content.
When you set an exclusion policy to exclude users based on Windows version, a condition is placed in all use licenses that prevents them from being used on clients that are running Windows 98 Second Edition and Windows Millennium Edition. You must enable Windows version exclusion on the Exclusion policies page of the administration Web site of each cluster on which you want it to take effect.
