826232 refers to some Windows TroubleShooter. If it's not installed (the TroubleShooter) said update may indeed fail. Microsoft has yet to give you meaningful error messages so you as a Professional OS user get to research each KB Article and see if your OS would require this.

Take no offense as I note that some want a "click-here" OS and Windows 2000 is far from that...

Some of these patches can be manually downloaded and installed. That's what I do when Windows Update fails.
