Intermittent broken IP / PORT access - 9.Apr.2007 10:38:26 AM

Greetings, I am new here so please forgive a beginner.

I have a web server in a DMZ and the web server has many IP's mapped to it.

The ISA 2000 is installed on 2003 advanced server. Web server is Liinux.

If I reboot the ISA, everything runs exactly as I would want.

One of the websites does an auto page refresh every minute or so.
After some random period of time, the site that has the auto refresh
stops working (for Internet connections). I can get to all the other IP's
on the web server from the Internet. If I go to the ISA and open a browser
the site that fails, will work from the ISA browser.

If I go to the Internet connected computer, the web page fails, BUT I can
ping the IP of the failed website.

I found an atrticle at http://www.isaserver.org/articles/ISA2000_POP3Access.html?printversion which kind of looked like what I was experiencing but that did not seem to help.

I also tried this with Intrusion Detection turned off, but it made no difference.

Whenever the website is not available, I can reboot the ISA and all is well again...
at least for a while but certainly this is unacceptable.

I have been trying to figure this one out for several days now and getting a bit
frustrated at this point. Can anyone tell me where I might be messing up ?

Thanks in advance,
