Dreamweaver installed, by chance? If so, see the following TechNote from Adobe:

I tried opening Vista's help. It worked yesterday but not working today.
Only change, I installed Winamp and did a reboot afterwards.
I get a dialog box:
Windows Internet Explorer
Internet Explorer cannot download / from help.
Internet Explorer was not able to open this Internet site. The requested
site is either
unavailable or cannot be found. Please try again later.
Any ideas?
