vbscript change from parsing groups to OUs

I've got a vbscript (below) that parses AD groups.  For each member it tries to ping, if successful it tries to connect to the WMI DB, if successful it quieries for NIC properties.  It works very well, but I'm having trouble adapting it to look at an OU (and sub OUs) rather than a group.  

Thanks!
