Win 2K eDir server as Reference Time Svr

I have 4 servers in my tree. Windows 2000 has eDir 8.7.3 on it and holds the master replica. I also have 3 NetWare 4.11 SP9 servers in the tree. I want the NetWare servers to see the Win 2K server as the REFERENCE server for time. I found docs that tell me I need to configure the Windows server to go toan external time source (NTP) but I can find nothing telling me how to tell the NetWare boxes that the Windows 2000 server is the REFERENCE server. Is this possible?
