The non-administratively available Outlook View Control SR-1 update was the culprit as stated in the first article I linked.
Thanks anyway.
Administrative Update:
An administrative version is not available for the Outlook View Control update. The Microsoft Office 2000 Resource Kit contains several options for deploying the client update in your enterprise environment. For more information, click the following link:
http://www.microsoft.com/office/ork/xp/journ/ol2k-vc.htmIf your Office 2000 installation was performed from an Administrative installation point and you are using Admin patches, you can still apply this client patch to your machines because it is not a Windows Installer patch. The ActiveX control mentioned in this article that this patch is designed for is not part of the original product so there is no reference to these files in the Data1.msi which will enable this patch to be distributed to the client machines.
How to Determine Whether the Update Is Installed
The update adds or replaces the Outlctlx.dll. Outlctlx.dll version will be updated to 10.0.0.3124.
Other Information
The Outlook View Control was never installed as a component of an Office or Outlook installation. If you have this ActiveX control installed on your computer it has been installed by using one of the methods outlined in the Microsoft Knowledge Base article Q281618.

NOTE: You can install the Outlook View Control update even if you do not yet have the Outlook View Control installed on your computer. This ensures that you have the updated version of the ActiveX control installed on your computer so that you are protected in the event you utilize the control in the future.
