Thanks Paul for your answer
Sometimes the solution is a lot easier than you can imagine.

In this case, this is a website we will host for a child company (our UK 
branch), they host their own DNS server so they control their own records.
I found out some traffic going to another of my ISAs, and had nothing to do 
there, so after a simple nslookup I discover that my friends in UK had 2 DNS 
records with the same name and different IPs.
So I guess the server where the IIS resides was resolving 1 time one IP and 
then the other one.

Why ISA was complaining or showing the complain of somebody else about 
"NOT_ENOUGHT_MEMORY"? well that part will never have an answer as many of the 
weird ISAs messages.

Thanks a lot to all for your help

My first thought is that it might be a host header issue.

You did mention that you have one rule for both sites.  I'm assuming then that 
both sites are running on the same IP address.

I'm also assuming that one site it pulling up just fine.  That tells me that 
the rule is working and passing traffic correctly.

If they are on the same IP address,  make sure that you've got the rule to pass 
the 'original' host header from the client.

If you are not passing the original host header, then only one of the sites 
would pull up.  Also, make sure that your host headers are properly setup on 
your IIS box.

To verify that the original header is sent, in ISA 2k6, it's on the "To" tab.  
Make sure to check the box that states "Forward the original host header...".

Also, you might want to check "Request appear to come from the original client" 
if you're doing any kind of logging/stats reporting on the IIS box.

Good Luck and have a wonderful day! :)

Hey Jim, tks for the reply and sorry for my delay, my phone got broken.
I understand the NOT_ENOUGHT_MEMORY message, but why if I access the same web 
publishing rule as www.siteA.com<http://www.siteA.com> and then as 
www.siteB.com<http://www.siteB.com> with the first one work and the second one 
failed?

Any clue?

"ERROR_NOT_ENOUGH_MEMORY" is pretty clear; ISA can't process the request 
because the requirements you and the request imposed on it exhaust whatever 
remaining user-mode memory is available to ISA at the time.

Odds are, you're trying to compress everything in sight and if so, this is a 
BAD idea in the extreme.

Hey everybody

I have 1 website running on IIS 6 on a windows 2003 server with SP2 on it.
That was the presentation for the IIS

From the ISA point of view I have the same IP, used by 2 different DNS records 
and pointing to the same rule (or actually the listener is listening on that 
IP). There is only 1 rule and 1 listener for those 2 websites.

http://uklink.mscuk.com/
http://msclinkuk.interlink.bz/

The second one works fine, the first one just in some cases and refreshing 
several times it works with some errors for images not being downloaded or 
things like that.

For the working one, of course the ISA log looks beautiful, for the one failing 
ISA is showing on the log the following error:

The rule on ISA was created accepting all request (on the public name tab), and 
the IIS is listening for incoming port 80 traffic, it doesn't matter which 
website are the request referring to.

I have no idea what is going on here.

Any idea out there?

Thanks guys
