it seems ive logged on as a different user.. anyway its still me.. synchro...
i forgot to mention that i found a help page that mentioned that there is a
hotfix for this issue... it has something to do with dns trying to reslove
the ip address of external pages, which it cant do... they say this is why
its slow.. but after running the hotfix, and the additional script that goes
with it.. nothing changed...

How do you handle DNS for the LAN and Internet?
I'm not saying it has anything to do with those links,...I'm just looking
for a place to start with the overall problem.
Also, how is the logging configured for the ISA? (text files, SQL, etc)

tried both links - We're sorry, but there is no Microsoft.com Web page
that
matches your entry. It is possible you typed the address incorrectly, or
the
page may no longer exist. You may wish to try another entry or choose from
the links below, which we hope will help you find what you're looking for.

For starters, you may want to see the document on firewall policy best

The type and order of your rules can have an impact on performance.
You should also review the performance best practices at

our business is using ISA server 2004 enterprise edition with sp2.
we have a t1 line and we have noticed a dramatic decrease in its
performance
Since we upgraded to ISA 2004.(for example browsing the internet with
the
firewall on, and the cache off, our t1 performes like a 56.6 modem at
best).
When we go around the firewall, or disable it, the connection speed is
very
quick again. We dont know why our speed is so decreased when the
firewall
is
active. The only fix we have used is to use the cache, which of course
appears to fix this issue, but does not really get to the heart of the
problem.
does Anyone have any configuration suggestions, or any ideas as to why
we
may be losing speed. I cant imagine that the firewall would slow our
connection this much if it is configured correctly
Thanks
