D2 does not work with any client version past 1.109. You can download the 1.109 DLL here ->

Changes from Tolakram:
Cleaned up crafting code a bit so that when a new D2 item is created the sockets are displayed. In addition I added the following items:
Socket Drill that can be used by any crafter who has a metalworking skill of 900 or more. The drill creates a socket in any unique item. Items can have up to 11 total bonuses. Drilling a newly created crafted item will turn it into a D2 item.
Essence of Diablo potion. Dropping this potion on a newly crafted item will turn it into a D2 item with 8 sockets.
Both these items are available from the apprentice crafting merchant in Act I and in housing.
