Hello I have a client who is trying to upgrade from isa 2000 to 2004. Any ideas on the following scenario?
I already configured the New Server and Installed ISA 2004 on the box with all service packs. I thought I could just rename the new ISA box to the Old Isa and save me a lot of changing around. I would also keep the IP's the same as the old one.
We tried the configuration yesterday. Dropped old proxy -deleted name from AD, then brought new Isa up with the exact same settings as it's predecessor. I was able to go out to the internet NOT using the Proxy (which you should not be able to do) and I could see all network computers and AD -but I could not ping the proxy and no one was able to go outside the internet.
