If it is really a 404 it means that you are requesting a page which does not exist.
In rare cases it might also indicate you are passing an invalid Cookie with your request.

More ominously it could be an indicator that you have spyware on board.
E.g. the spyware site intercepts your request, then sends back a fake 404.

Neither of those symptoms appear like 404.
They look more like a problem with connectivity.
E.g. invalid lookup provided by override in HOSTS file,
invalid lookup cached in the dnscache, or invalid lookup
being provided by your ISP's DNS.

Another spyware related possibility would be having a bad DNS.
Some users have found that their DNS has been overridden
permanently by a suspect DNS address, e.g. instead of getting
one dynamically from their ISP (or vice versa, they know they
are getting deficient service from their ISP's DNS and need
to switch to a different one.)


You would have to do some kind of packet trace to check
for either possibility. In the case of malware, having a active trace
running might have even the effect of making it mysteriously stop. ; )

All the more reason to suspect a networking cause.
I'll take a chance and assume that "upgraded to IE7" implies
that your OS is probably XPsp2? Cross-posting to XP networking.
