ISA 2004 Publish Web Server Problem

[Nij.UK]

Hi

 

Im trying to publish our school intranet site to the world.

 

Im running 2k3 and ISA 2004 and 2k3 and IIS6 on the web server.

 

I think i have set up IIS6 correctly, and we can get the site to work perfectly on the internal network, but whenever i try and access it from outside of school i get an IE error saying

 

Error Code 64: Host not available

Background: The connection to the Web server was lost

 

Now i know that the URL is getting into school and to the ISA box, because i can see it when i am monitoring on ISA...

 

It just seems to be that there is problem communicating between the 2 server.

 

I used the web publishing wizard within ISA 2004

 

Can anyone help.. or put out where to look?

 

Thanks

I've never got the web publishing wizrd to work. Have you tried simply using the server publishing wizard and publishing port 80?

Ive just had a look at that... when it asks you to select a protocol, one for HTTP doesnt seem to appear, does that mean i have to create a new protocol for HTTP.... but i know one already exists within ISA

I tried publishing it as just a server using the wizard, and i still had no luck with it

 

Any suggestions would be grateful

You do have to create a new inbound rule for HTTP traffic.

Please NOTE: there is an issue within ISA 2004 that if you use upstream proxies (there is the ability to forward all traffic to an upstream proxy) then local http traffic does not work, please see the KB article below:

 

Potential issue with local web traffic and the webproxy.dll filter in isa. See the proxy loop issue.

This affectd me when I wanted to publish our web server and Sharepoint server.

 

Took a while to find it....

well i have just noticed something wired, and im guessing ISA server is blocking something.... because i can get to the web server on any machine internally and view the pages, but when i come to do this from the ISA server it cant seem to find the webserver....

 

but i can ping from the isa server using IP and server name and it pings fine.....

 

Could this a possible reason why it cant seem to forward traffic onto the webserver??

Im now getting a Error 404 Not Found , The requested item could not be located.

 

What ive noticed now is that, when u type in the name of the webserver eg

 

http://webserver/ it is finding the intranet on the web server... but when u try to access the site through the server ip address it cant find the webserver. This is only happening on the isa server, all other client and servers can access the intranet either though ip addess or servername

 

Any suggestion

 

thanks
