I have a scenario where users of the firewall client can browse certain sites but not others. For example, I can go to www.cnn.com but can't get to www.hp.com

When I monitor the session I do not see any http connection being made to the ISA server. However, once I go to a different site I see the connections.

Doews anyone have an idea why the firewall client can't browse some sites but not others??

Thanks!

Scott

Forgot to mention this is on ISA 2004 Standard with Sp1.

Type at the prompt

c:\>ipconfig /flushdns
c:\>nbstat -RR
c:\>arp -d

Go to your browser and clear the cache.

Now try to go to cnn.com and hp.com.

Now try http://192.6.234.8 or http://192.6.234.10

If you still have trouble, see if you can resolve the www.hp.com name by nslookup.

Check all your domain sets to make sure that you don't have *hp.com blocked.

Finally, I would install the Ethereal on a workstation and do packet capture.

That still didn't work. I don't see any traffic to the ISA server when I make a request to www.hpcom. Yet it works fine going to other sites

Maybe you somehow configured the client to go direct to that site.

Well, I got the Automatic configuration to work and after getting that I can now browse to these sites.

Very weird. Thanks to everyone for their help
