In Windows Vista, you cannot access rights-protected content by using a local user account from a computer that is located outside the domain

Consider the following scenario:

• You access rights-protected content by using a local user account.
• You use this local user account from a computer that is located outside the domain.

In this scenario, you are not prompted for your credentials to authenticate to the Windows Rights Management Services (RMS) server. Therefore, you cannot access the rights-protected content.

This problem typically occurs in scenarios in which you log on to a home computer that is running Windows Vista by using a local user account. Then, you use Microsoft Office Outlook Web Access (OWA) to access the e-mail account from your workplace. In this scenario, you may not be prompted for your credentials to access the RMS server.

This problem occurs if a program calls the DRMActivate function without passing the DRM_ACTIVATE_SILENT flag. The DRMActivate function requires the DRM_ACTIVATE_SILENT flag to be passed. The DRMActivate function fails with an invalid argument exception if the DRM_ACTIVATE_SILENT flag is not used.
