Cannot browse Internet Sites with IE7+ and Vista b2, Can browse LAN sites

K

I have a good LAN connection, DHCP allocated IP address, DNS appears to
work, and I can browse web content on the LAN.

I cannot, however, browse web content on the far side of my home router.
Anything outside the LAN returns a message in IE that there is a server
problem. I can see the DNS resolution in the task bar of IE 7, but no web
content.

Also, activation isn't working. Perhaps if I solve one issue, I can solve
the other.

Try going here on the affected computer: http://69.93.5.112
Does that page load up? If so... it's definately a DNS issue ;o)

Thanks for the reply. DNS is working, but still cannot browse outside of the
LAN. Hypothesis is weird IE security or router issue !? Machine is dual boot
with XP and Vista. XP works fine so physical network layer is functioning.
Tried manually setting DNS servers but still no good.

Sigh.

I had an issue really similar to yours on my Windows 2003 server. My server
hosts webpages using a service by dynu.com because I'm on a dynamic ip
address from comcast. Anyway, I could view my webpages that were being
hosted from a remote site, I could Remote Desktop into my server, but from
my server I could not view anything related to http. I posted that problem
in the windows.server.general newsgroup and 2 smart fellas recommended I
remove IE Security Enhancements from Add/Remove Windows Components. I don't
know if Vista has IE Security Enhancements, but check it out.

I fixed the problem! Problem was SPI on my home router dropping packets.

I have a ZyXel router, new, pre-N, MIMO.
I checked the router logs and they were filled with dropped packets. Reason
= SPI (Stateful Packet Inspection) bad packet sequence number.
I disabled SPI, and problem solved!
All XP machines in side the router never had this problem

Does firefox or another browser work? Can you ping an external IP out
on the web? Is there any other computers on your lan having a similar
problem?
