Macro not working for fetching data from Active Directory - excel

Question

Recently I changed my laptop and below given macro is not working in it. where as in my old machine it is still working. I cross checked all the references and enable it as per my old machine. I also cross checked with some other guys and they told me to use ADODB.Connection line in below code.
Also When I checked macro line by line items by pressing F8 key its is showing blank in "idapstr" line where as in old machine when using same macro its working fine.
Error code is on below line code "Set x = GetObject(ldapstr)" is mentioned below :-
**
" run time Error -2147023541 (8007054b)
Automation Error
The Specified domain either does not exist or could not be contacted."**
Can anybody help me out how to add the "ADODB.Connection" code or how to adjust this existing code ?
