Ever since I installed Office 2003 last evening, I have
not been able to use IE to go to any http://localhost/...
addresses.

I am running Windows XP (Pro, of course). What I get
when I try these addresses now is either a hang (status
bar perpetually "trying"), or a partial HTML display (as
in, perhaps the last 300 bytes of the index.htm, for
example).

I've already tried rebooting, stopping and restarting
IIS, adding and removing virtual IIS folders. IE will
display these pages just fine, including references to
stylesheets and so on, if I attempt to open from Windows
Explorer (this action, as far as I understand, doesn't
involve IIS, as it's a "local" open, just as if it were a
Word document or such).

Any ideas?
