John,
I promise that a lot changed over the weekend. That is the time when the network Nazis are gleefully at their best.
Or this may turn out to be a sad lesson about MS auto-update.
A further test: try pinging Apollo with the default settings, then 1000 packets, then 1000 1500 byte packets.
If you can't ping Apollo, things should not be working for you.
If you use ping with an invalid setting, it will tell you what all the switches are.
John
