Finally, with the support of this board and others, I was able to convince foxISAPI and IIS 5.1 to cough up a "Hello World" return page. THANKS FOLKS!
I would also reccomend that one of the first things we should do after upgrading to XP Professional and installing IIS would be to run CHKDSK.

Anyway:
My plan was to retrace the steps required to get that first bite. But, before I went there, I modified my [Rick's] hello world sample to read "Hello World Second Edit".

This is the unusual part:
IE6 continued to say just "Hello World" (the older exe), while Nestscape returned the "Second Edit" page.

Are there re-configuration issues I need to address when I make changes to the server? Do I need to un register and register the COM again?

Thanks
Terry
