Christof,
FWSERVER starts up ok and the taskbar shortcut menu item for controlling things is available, we get 2 channel windows open. As soon as the web page is hit it barfs up the error referenced in the original post.
>Are one or more fwserver.exe running? What user is Apache running and what are the FoxWeb EXEs using? They might not find each other. When you open Process Explorer from SysInternals, do you see named Semaphores and the like in the FoxWeb applications?
