It doesn't work.
ox=createobject("iisNamespace") returns a "Class definition not found error"

>I believe this is similar to IIS 4.0. In IIS 3.0, you could change a registry key, but IIS 4.0 requires a change to the metabase. Copy the following into a .prg, compile it and run it. It works for IIS 4, so I think it will work for you.
