How to Resolve WDICA error Event ID 0

Windows Server 2003 running Citrix 4.5 logs the following error in System Log prior to a system stop, bluescreen, and subsequent system restart:
Event Type: Error
Event Source: WDICA
Event Category: None
Event ID: 0
The description for Event ID ( 0 ) in Source ( WDICA ) cannot be found. Either the component that raises this event is not installed on your local computer, or the installation is corrupted. You can install or repair the component on the local computer, or contact the component manufacturer for a newer version.

Citrix Tech support recommends updating WSXICA.DLL (version 4.5.3900.1) which was previously a private update requiring opening a ticket with Citrix support.

As of Feb 2, 2009, this updated dll is included in Citrix hotfix PSE450R03W2k3032. Prior to installing this hotfix, Citrix 4.5 Rollup 3 will have to be installed which also requires updating the farm to Citrix Web Interface 5.1.1.
