Ah the joys of debugging a VFP Web Service through COM <g>...

Most likely the issue is security. If you can instantiate the server from a standalone EXE or WSH script but not through IIS the first thing to check is security.

I don't think that the VFP IDE installation has anything to do with this...

Unfortunately it's very difficult to debug things like this. The best thing to do is to create an ASP/ASP.NET page and call your COM server from it - that way you can simulate the COM environment a little bit more easily and you might be able to get more detailed error information from that end.

Good luck,
