If you are unable to connect with ICA After Installing the Microsoft Rollup 1 for Windows 2000, here is a workaround

If 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

This 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:

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.
