Hello, I used to set up my Web Proxy clients to use a proxy.pac file. The proxy.pac file was in an IIS server with no ISA Server. I was running Proxy 2.0 and ISA 2000 as Proxy Server. No I am trying to have all in one box, I mean, the ISA 2004 and publish the PROXY.PAC file in the same machine. Can I do that?. How?. Thanks.
