Hi Colin,

>However, a similar line, dso = GetObject("LDAP:"), in VFP gives me the error, "OLE error code 0x800401ea: Moniker cannot open file."

That's a VFP 6 issue fixed in VFP 7. Erik Moore covered this bug and solutions in his ADSI article in the February 2001 issue of FoxPro Advisor (http://msvfp.advisorguide.com/doc/04913).
