Here's the thread I'm referencing:

I'm seeing the same problem as they did (Automation server can't create object) when accessing any function on the Action screen, even PING. The last message suggests that a lot more needs to be configured in IE than the one setting in the KB article (which was already configured that way for me anyway, here in IE8 on Win7), but what are the settings and why aren't they in the article? It sounds like I probably won't want to do them anyway, if it drops security that much, and FF does work, but it would be nice to get IE working.
