XA600W2K8R2X64018

Servers running XenApp 6 can become unresponsive when shutting down. The issue occurs when the picadm.sys driver encounters certain error conditions that prevent it from shutting down in an orderly fashion. Also, servers might experience a fatal exception, displaying a blue screen on picadm.sys with bugcheck code 0x22 (FILE_SYSTEM).
If a session is disconnected while it is still reading or writing a Client Drive Mapping (CDM) file, the resulting deadlock condition can prevent servers from accepting new session requests.

This fix addresses a security vulnerability. For more information, see CTX128169

XA600W2K8R2X64026

Attempts to launch a published application that resides on a mapped network drive rather than on a XenApp server failure
When connecting to a server running Windows Server 2008 R2 with Service Pack 1, Terminal Services can exit unexpectedly. This causes users to experience a black screen when logging on and the logon process fails to complete.

Servers might experience a fatal exception, displaying a blue screen, with bugcheck code 0xf4 on IMAAdvanceSrv.exe.
Servers attempt to launch Windows Internet Explorer from an http, https, or mms hyperlink embedded in a streamed application failure. The issue occurs because XenApp 6 does not create the HKEY_CLASSES_ROOT\htmlfile\shell\opennew\command_backup registry key as part of server file type association.
