Document ID: CTX107051, Created on: Jun 30, 2005, Updated: Jul 1, 2005
Products: Citrix MetaFrame XP 1.0 for Microsoft Windows 2000, Citrix MetaFrame
Presentation Server 3.0 for Microsoft Windows 2000
Symptoms
Users connecting with ICA sessions receive a blue background and the Windows
GINA does not display after installing Microsoft Rollup 1 for Windows 2000 SP4
on Metaframe XP and MPS 3.0 Servers.
The console might be unresponsive and have high CPU utilization within the
winlogon.exe process.
Cause
Issue occurs after applying the Microsoft Update Rollup 1 for Windows 2000 SP4
(KB article ID 891861) to Metaframe XP FR3 Service Pack 4 servers and MPS 3.0
servers.
Workaround
Citrix recommends the following temporary workaround:
Caution! This fix 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.
1.) Open Regedt32
2.) Navigate to the following location:
HKLM\Software\Citrix\Ctxhook\AppInit_Dlls\Smart Card Hook
3.) Rename the ?FilePathName? key from ?scardhook.dll? to ?scardhook.dll.old?
4.) Reboot the server
Please Note - If you require smartcard functionality in your environment the
temporary workaround is to uninstall the Microsoft Update Rollup 1 for Windows
2000 SP4 (KB article ID 891861).
Status
Citrix is currently investigating the issue and working towards a solution.
