It sounds ike you need to add z.exe to the list of allowed Web Service Extensions. For details please refer to the Enabling FoxWeb to Run on Windows 2003 section in the Configuring your Web Server page on the FoxWeb documentation (http://www.foxweb.com/document/WebServer.htm).

We've been using FoxWeb for years. I copied foxweb.exe file to z.exe. This has worked fine on our current webserver. We are currently setting up a new webserver, and now when I try to copy the .exe to what I want, I get a 404 error in my browser.
works fine, but
Returns a 404 error.
I cannot remember if I had to do anything special to get the renamed .exe file to work on the current server.
