I am using PWS for WinNT WS4. I have granted rights for IUSR. I see my COM server in DCOMCFG. But I am getting "FOXISAPI Call Failed... Class id for MyServer.MyClass not found. Err code = 800401f3: Invalid class string" from the browser. I've done this before, but with IIS 4.0 and it was a long time ago, so I've forgotten. Any clues?
