Problem with AD LDAP Ranges

from vb, this ldap query works for getting all the records:

<LDAP://10.0.0.1>;(&(objectCategory=Group)(cn=Group1));distinguishedname,name,member;subtree ........
however, if I try to insert a range into this query the recordset comes back with nothing:

<LDAP://10.0.0.1>;(&(objectCategory=Group)(cn=Group1));distinguishedname,name,member;range=0-9;subtree  
'this does NOT work and there are a few hundred members

Why doesn't that 2nd query work above?  Am I missing something with the RecordSet?  Does anyone have some example vb code that they have used with ldap ranges that I could compare?

I have read a very similar question from Pber posted here:
