Topic "1.14 Why doesn't the ISAPI work on my virtual root?"

>I've been trying for a couple of days now to create a VFP based Web Service. I've tried the VFP examples in MSDN. I've tried the examples the SOAP 3.0. Nothing seems to work. I've read and re-read the docs. Carefully followed all the steps, and no luck. I keep getting an unknown COM error (0x800A13BE). Is this a problem peculiar with VFP 7.0/SOAP 3.0? Or am I just being terribly thick about something.
