Hi Brian!
If I were you I'd start by configuring AOLserver to listen on localhost cutting out as many sources of malfunction as possible.
Are you trying to connect from a browser on the webserver host itself or from anoter host on a LAN?
Your server is named "express" - make sure you have a virtual server named that (you can rename or make a recursive copy of /*yourserverhome*/servers/server1).
Where is OpenACS installed? If it's in /web/express/ you must alter the "source" path on the second to last line in the config file to something like: source /web/express/parameters/express.tcl
In this case you may need to change the pageroot: set pageroot /web/express/www
