objConnection.Provider = "ADsDSOObject" 'The ADSI OLE-DB provider
objConnection.Properties("User ID") = ""
objConnection.Properties("Password") = ""

strquery = "<GC://" & "Servername" & ":389>;(objectClass=*);cn,mail;subtree"

objCommand.CommandText = strquery
objCommand.Properties("Page Size") = 99
