Does anybody know how to disable AutoProxyCache??? I followed Q271361 from Microsoft but it's just not working for me. I have 2 ISA servers for web cache. I'm using a .PAC file that's suppose to route http to the second ISA server in the event that the first ISA server goes down. It worked, the only problem is, I brought the first ISA server back up and it's still going to the second ISA server. I modified the client registry to disable AutoProxyCache per Microsoft but it didn't work. Please advise. Thanks,
