Here is a skeleton of a .reg file I use to manually setup NTP clients. After running this it might be a good idea to: net stop w32time and net start w32time. After this check eventvwr in System Tab and look for Source win32time look for Event ID 37 or 35.

Hope that helps, A Thanks for the reply. I guess I should have made my question more clear. I'm more interested in the logging capabilities of ntpd in server mode. Because my OpenBSD workstation can sync to the server, ntpd is working. I thought logging might give me some clues about what is going on with XP. So far as I can tell right now, it isn't even attempting to contact the server. Everything involved is on the lan with a 192.168.0 address, hidden from the internet by a bridging firewall. PF isn't enabled on the ntpd-server-box in question. Jeff

You might try a tcpdump on your ntp box and see what (if anything) the windows systems is sending you. Ditto on the windows system. (Ethereal? windump?) See if it is even trying to talk to your ntp server on 123/udp. DS
