Issue that is fixed in this hotfix package

When you use Microsoft Live Essentials or Microsoft Accounts together with Microsoft Application Virtualization (App-V) 4.6 Service Pack 2, a Desktop Configuration Refresh (DC Refresh) authentication may sometimes fail. For example, you may be prompted for your credentials every time that you start an application.

This problem occurs because of an authentication issue in the handling of the Real Time Streaming Protocol (RTSP) that is used with these services.
