The default settings for the Windows Media Rights Manager 10.1.2 SDK do not include delivery of revocation information

The default settings for the Microsoft Windows Media Rights Manager (WMRM) 10.1.2 Software Development Kit (SDK) do not include delivery of revocation information. The default settings also do not include the certificate revocation lists (CRLs) at the time of license acquisition.

Content providers that use WMRM 10.1.2 must review their license delivery settings to enable support for delivery of revocation data. When the revocation data and CRLs are not available during license acquisition, you may be redirected to the following Microsoft Web site: Additionally, the WMRM clients receive the following error message in Microsoft Windows Media Player 11: When you click Yes in the error dialog box, you are directed to the following article in the Microsoft Knowledge Base:Note There are no visible symptoms on the WMRM server.

This problem occurs when you try to play the content that you previously obtained if the content is protected by using Microsoft Windows Media Digital Rights Manager (DRM). You may experience this problem when either of the following conditions is true:

• You have upgraded to Microsoft Windows Media Player 11 from Microsoft Windows Media Player for Windows XP, from Microsoft Windows Media Player 10, or from Microsoft Windows Media Player 9 Series.
• You have upgraded to Windows Vista from an earlier version of Microsoft Windows.

To resolve this problem, WMRM 10.1.2 content providers must configure license servers to deliver revocation information to client applications that request licenses. The AddRevocationData method adds revocation data to a license. For this resolution to take effect, Windows Media Player 11 clients must acquire a license from WMRM 10.1.2 after they are upgraded.

This behavior is by design.
