Just finished doing that. Check out KG document OTI-99-0057. Two things to add to the document:
1) You will need to edit tables F9650 and F9651 as well as the tables listed.
2) You need to edit ALL of these tables on the ES and also ALL of the local tables on the DS.
Otherwise, the directions are complete and easy to follow. Make sure that you uninstall Terminal Services from the W2K machine.
