Anyway, I run the utility above and it fusses about a missing .DLL that is needed for conversion. What DLL is the utility referring to? I have also copied the complete WINS directory (.log and .pat) files to the new W2K box along with WINS.MDB. However, I receive the same results. Keep in mind we want to move WINS to a new W2K server, not just upgrade the existing NT box. The NT 4 box is also supporting DHCP and a secondary DNS Zone (Bind 4.xx). Thanks in advance, Jerry!!
