i am in standalone environment (no active directory), i have windows 2000 installed (with all patches and service packs) and ISA server 2000 (Enterprise) is running on that server, NOW PROBLEM IS IT that when i am upgrading from ISA server 2000(Enterprise) to ISA server 2004(Enterprise)it asks for the location of "Configuration Storage Server" i leave it blank, than it asks for the "Array server" (I have no array, just one ISA server on which im running installation) so i also leave it blank...finally i get the message of installation failed. I know i must have to install "Configuration Storage Server" but installation wizard is asking me for to "LOCATE Configuration Storage Server" instead of asking me for CSS installation.
