Windows 2000 prof, IE6 SP1
There's plenty of crap on the web about similar problems, e.g. at various forums, MS community discussion groups, MS knowledge base, etc.... Although I've not found anything that works on this issue. FYI - This should not be confused with a script error issue that seems to also be troubling some people, nor an error some people are getting when they attempt to load updates (these are issues addressed in some of MS knowledge base).
I've gone through making sure that IE doesn't have something disabled, e.g. tools>internet options>advanced, etc...
I don't have any issues with popup blockers, firewalls, etc...
I've done the start>run>driver stuff
