RE: Avoid DNS

Simply restarting the services does not clear the cache in my experience.  The 
best way to clear the ISA cache is to stop the proxy service and delete the 
dir1.cdat file.

Actually, I was referring to Web proxy clients, but the same applies to FW 
clients.
You can reset the ISA DNS Web Proxy and Firewall DNS cache by restarting the 
services.
This article 
http://isaserver.org/tutorials/ISA_Clients__Part_1__General_ISA_Server_Configuration.html
 deals with how to minimize the ISA services DNS caches.

Yes, these are proxy clients. The workstations have the firewall client loaded. 
I did try adding the ip address to the hosts file on the isa server before 
coming to the list but it didn't appear to work. If I ping the domain name from 
the server I do get the address back that I want but when I try to view the 
site in the browser I get the other one. I cleared the cache from my browser, 
no help. Is there an easy way to clear cache from the ISA server?

..unless it's a web proxy client, in which case, the ISA performs name 
resolution.

Given that this test failure is a web site, I'm inclined to think that this is 
the case.

Place the "fake" site IP in the hosts file on the ISA and restart the web proxy 
services.

First, trying to have two different IP addresses for 2 different websites with 
only one FQDN is asking for problems.

 

If the workstation is not using the HOSTS file first, something is wrong. It 
must always use the HOSTS file first.

 

Please check the configuration.

How can I configure the ISA server not to use DNS to look up the ip address of 
a particular domain name? 

 

Here is the situation. The website is being updated. The old website is still 
online at www.ourcompany.com <http://www.ourcompany.com/> . The new website is 
under construction and being housed on another server. Users need to be able to 
type www.ourcompany.com <http://www.ourcompany.com/>  and get to the under 
construction website not the old website being used by clients. 

 

Before ISA server I could simply add (newIP address) www.ourcompany.com 
<http://www.ourcompany.com/>  to the host file of the workstation. But now the 
workstation doesn't go to its host file to resolve names it uses the DNS on our 
ISA server. Both website locations are off-site. How can I specify the IP 
address of my domain so that the workstations will look only at the under 
construction location and not the one in DNS?
