Ok, what does web mail inboxes, dell configuration pages, and shopping
carts have in common.
On my new 2004 ISA Server/Windows 2003 I am unable to get to these types
of sites. I have an older ISA 2000/Windows 2000 running with the same
setup and it has no problems accessing these pages.
Clients all run XP/2000 with latest patches. IE for the browser. They
are all firewall clients.
Simple branch office setup.
Network setup is this:
Internet
|
PIX - Service Center
|
Router
|
|----T1(ATM)
|
Router
|
ISA - School
|
network
Do not think that it is a service center issue because ISA 2000 is
working perfectly.
I have tried setting the mtu on the external nic with no results.
I have tried with and without cache enabled.
I have tried reinstalling.
I have only a couple of access policy. 1)granting access to DNS servers
2) allowing all traffic from internal to external
Here is the message I am getting:

Explanation: The request timed out before the page could be retrieved.
Try the following:
* Refresh page: Search for the page again by clicking the Refresh
button. The timeout may have occurred due to Internet congestion.
* Check spelling: Check that you typed the Web page address
correctly. The address may have been mistyped.
* Access from a link: If there is a link to the page you are
looking for, try accessing the page from that link.
* Contact website: You may want to contact the website
administrator to make sure the Web page still exists. You can do this by
using the e-mail address or phone number listed on the website home
page.
If you are still unable to view the requested page, try contacting your
administrator or Helpdesk.

I have posted to message boards and to this list a couple of times with
none of the helpful suggestions working. Found one message board entry
that looked promising but turned out to be misconfigured websense
server. I am also using Websense at the main office. Is anyone else
using ISA 2004 and going through a websense server? Is there something
different between ISA 2000 and ISA 2004 that would affect this
connection?
One last weird thing: you can tell Dell's pages are going to mess-up
because some of the pictures load and some do not. If a picture does not
load then the next page off of any link will give you the above error.
Anyone have any ideas?
Anything I can check?
I am out of things to try?
Thanks in advance.
