Users Facing Blue screen on Citrix PS 4.x for Published desktops

Problem Description:

Users not able to login to Published Desktop Applications and they see just a Blue screen.
However RDP login works fine. The problem appeared on Citrix PS 4.x platform in windows 2003 servers.

Root Cause:
 This issue has appeared after the server has been updated with two patches from Microsoft KB2922229 and KB2936068

Solution:
1.  Uninstall both the patches and reboot the server. You need to also block these patches on your automatic patch system like WSUS otherwise these will get instllaed in next patching cycle again.
2. Change Farm Level Settings

For PS 4.0:
In Management Console, right-click the farm name and hit Properties.  Open the MetaFrame Setting section and uncheck "Use Client's local time"

 FOr PS 4.5

In Access Management Console, right-click the farm name and hit Modify farm properties>Modify all properties.  Open the Farm-wide>Presentation Server>General section and uncheck "Use Client's local time
