Internal Web Servers get 502 Error

Hello,
 We are using ISA 2004 Standard with a basic Edge Firewall setup. My
client is IE Web Proxy, Firewall Client and the default gateway is
pointing to ISA.
 
Anytime I want to access an internal web server device, such as my HP
jet-direct devices, or my internal switches web interface, I have to
manually enter the IP into my web browser in the advanced section in the
exceptions. Otherwise I get the brown Network Access Message: The page
cannot be displayed Error Code: 502 Proxy Error. The ISA Server denied
the specified Uniform Resource Locator (URL). (12202)

So after I enter the IP manually, and then I close IE and reopen, I have
to reenter the IPs all by hand again or I get the same error.

In IE, I have the box checked to bypass proxy for local, but still same
result.
Also, on my ISA server on the Internal Adapter Properties, on the web
browser tab I have the box checked for Bypass proxy for Web servers in
this network.

But I am still getting the error when I try to connect unless I manually
each and every time go in and type the IP into the exception box.

Any advice?
Thanks,
Paul Deen
