Presentation Server 4.5 for Windows Server 2003 x64 Edition


*Symptoms*

The Presentation Server Client for Macintosh is consuming CPU when connected
to Presentation Server 4.5.

*Cause*

The issue occurs because the server refreshes the smart card reader state
more frequently than necessary. This occurs even if smart cards are not
being used.

*Workaround*

*Caution! This workaround requires you to edit the registry. Using Registry
Editor incorrectly can cause serious problems that may require you to
reinstall your operating system. Citrix cannot guarantee that problems
resulting from the incorrect use of Registry Editor can be solved. Use
Registry Editor at your own risk. Be sure to back up the registry before you
edit it.*

Disable the SmartCard Hook entry in the registry on the server:

HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\CtxHook\Appinit_Dlls\smart card hook

Set "Flag" value to 0 (Zero)

*Resolution*

This issue is addressed by the following hotfix:
