New Problem - Can not connect to specific sites

[John Adams]

This problem just started about a week or two ago.

I can not connect to www.ea.com or www.adultswim.com. I can ping
www.ea.com, but not www.adultswim.com. They will not even work if I type in
their IP addresses directly.

I have tried disabling, even uninstalling my firewall software (OneCare) and
this had no effect. I tried "ipconfig /flushdns", no effect. I tried
clearing all cache and history, no effect.

The strangest thing, is that this happens to both of my networked PCs (Vista
Ultimate SP1 x64 and Vista Ultimate x86), but it does not happen to the
nintendo Wii. The Wii can connect to both of these sites perfectly. Only
the PCs can not.

What the heck?

Any suggestions>?

Some networks simply don't allow for ICMP request to be made to their
network.

I just want to view the websites, I don't care about pinging them.

I can't even view the pages through a web browser.

I figured it out!

I had enabled "ecn" on both of my vista desktop machines and this was
causing the problem. I guess the servers on those two machines don't
support ecn and dropped the packets.
I disabled ecn on one of my machines and voila, suddenly all the sites
worked again.

Too bad, though. Ecn is a great feature in concept.
