Thanks Tom that works like charm. I follwed the instructions on your book.
They can access the local FQDNS like http://intranet.company.org without going
through proxy. One problem I have now is if the users type http://10.10.5.2
which resolves to intranet.company.org, they get:
Error Code: 502 Proxy Error. The ISA Server denied the specified Uniform
Resource Locator (URL). (12202)
Obviously the browser is not recognizing the IP as local. What can I do?
If I tried FTP://10.10.5.10 in the browser that works fine. If I tried FTP
10.10.5.10 in the command prompt, it works fine too. so I know firewall client
doesn't deal with local addresses.
Thanks for your help.

Hi Tim,
In order to use the settings you configured for Web Proxy Direct Access in the
ISA firewall console, you need to complete the process by configuring the Web
proxy clients to use the autoconfiguration script. Autodiscovery will
accomplish this just fine, or you can do it manually or through Group policy.
HTH,
Tom

http://www.ISAserver.org I have ISA 2004 on w2k3 and it's an edge firewall. I
allow all protocol from Internal to External (this will soon be changed). All
three client types are configured in each workstation. My Internal machines
have problem accessing internal websites (No looping through firewall). If I
disable the proxy setting in the browser, workstations have no problem. I
check marked 'By pass addresses found in the Domain Tab" and also entered my
internal domain name in the Web browser tab of "Internal" network properties. I
still can't get the web proxy clients not to contact ISA for internal websites.
If I use the computer name instead of http://some.http.address.local,
everything works fine too. I was able to solve the problem (for the time
being) by modifying the "Allow all outbound traffic" rule with FROM: Internal
and TO: Anywhere. I had it preveoulsy as FROM: Internal and TO: External. I
think my solution is bit convulated. After reading Tom's book, I didn't
want to install Ethereal on my firewall but Network monitor has a big learning
curve. Your help is greatly appreciated.
