I think that last is perhaps a little unlikely. I'm not sure exactly
what the infrastructure of our network here at IBM is, but I strongly
doubt there is anything Microsoft between my RS/6000 and www.lego.com.
I just did a little bit of investigation, it might actually be my
system. I am also able to view the new catalog on an NT machine. I just
did a traceroute from the three different machines, and while this is
not absolutely the best method (it doesn't get past the firewall, is
there a way to do that, especially using http since the firewall might
route http differently than ICMP), only the first hop is different
between all three machines.
