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. The new website is under construction and
being housed on another server. Users need to be able to type
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 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?
