Thank you for your enquiry.
The latest version of the NDAP ActiveX controls requires manual registration before they are available for use. Details on how to do this are in the documentation (activex_ndap.html) in the installation folder; the following is quoted from the section on installation:
To register the controls, click Start->Programs->ActiveX Controls for Novell Services->NDAP ->Register Controls. You can also register the controls by running REGOCX.BAT file from the command prompt.
I hope this information is helpful.
