I have OS 10.3.4 with 9.2.3? (can't remember/tell) as "classic".
(I started using OSX in April). I have NetBarrier.
Recently I needed to dig up an old email message from the program
(Netscape 4.7) I used before I got OSX. While I was in there I
happened to notice that it can no longer load web sites. I then checked
my classic versions of IE and iCab, and found that none of them can load
web sites. After dozens of attempts I found that a few web sites would
load but most (including google.com) would not. I did of course check
that all the web sites I had tried were accessible from any browser I
have in OSX. I know I never had this problem back in April, during the
first few weeks of having OSX, because I was using Classic daily, but I
hadn't used it for at least a month when I noticed this

Any ideas?
