Perhaps a bit cheeky to disagree with Steve here, but I might as well share my experience. It probably depends on your isa configuration. I have renamed my stand alone integrated isa member server (so no AD on it) yesterday without many problems. Sure, just renaming the server itself didn't do the trick. I have also changed every occurance of the old name that I could fine in ISA, and after that I have also done that with the registry on the ISA server. Finally I have updated the .ini file the firewall client uses with the new name instead of the old one. My ISA box is running like a charm now, without any noticable differences compared to the before situation. I must admit that my ISA server installation is a pretty straightforward setup with little extra besides proxy and firewall. --Marc -----Original Message----- From: Steve Moffat [mailto:steve@xxxxxxxxxxxxxxx] You can't Steve -----Original Message----- From: Alex Decarli [mailto:decarli@xxxxxxxxxxxxx] I renamed ISA Server and all services on Isa is uniavaliable and it's with old name.
