Although the literature suggests that the workstations should be able to find the 
time server automatically since it is running on the domain controller, that does not 
appear to be true.  The error message received is

"Member of an NT4 domain. Cannot synchronize."

So maybe it only works in AD style domains, not NT4 style domains.

Run this little batch file once on your XP workstations to get them syncing with your 
ntp server on your local network.  The ntp server may or may not be the samba server. 
  Of course, you have to edit the IP address of your ntp server.

rem - filename XPtime.bat
rem - this works for windows xp to set up syncing with our ntp time server
net time /setsntp:
net stop w32time
net start w32time

Note that the procedure is different for Win2000 workstations.  Let me know if you 
need that too.
