Can't access some web sites

[Dragonfodder]

Since loading SP2, there are five or so sites that I can not access. bottom
bar say's "connecting to www.xxx" then 8-10 seconds later I get the notice
that it timed out. It is on these few sites that does this.. They are
normal sites... scottrade, americanexpress, etc.. not secure sites. I did a
capture and I am not receiving the SYN,ACK from the web server.... What
would cause this.. again, it only happens from these few sites. all other
sites come in normally.

Hope you can help
John

Could we back up the stack a bit? <g>

Where is the timeout occurring? During the DNS lookup?
During the HTTP connect? After the GET?
Which version of the HTTP protocol have you tried?

BTW since you can ping (could ping? last month's thread)
these sites have you tried checking your MTU size with them?

Good luck
