ISA does not find server after installing apache on solaris...

Hi Listers, Bear with me. I installed and configured the following programs on Solaris 7 running on an E-3000. Apache Web Server and Big Brother Network Monitor Will install DBAmon as well. I has ISA installed and running from the address: http:/bbankmain:/8080. When I had installed ISA, I opted to use the bundled http server and Perl engine. After installing Apache, and configuring Big Brother Network Monitor, which is working OK, at this point; I can't display the ISA web pages anymore. Perhaps someone can point me in the right direction to start resolving the problem. I looked at the document HTTP-CONFIG in the "isa" directory structure, but it does not provide detailed information on how to configure Apache to display ISA web pages. I know I need to start looking at the Apache logs. I'll search for them, but any help would be appreciated. TIA, Denmark W.
