Hi we using SP time sync on win XP and win 2003, everytime machine is restarted IP address to NTP server changes from 192.168.8.2 to 192.168.1.2. They are installed in supermicro servers. However, static IP address to server remains as it is even after restart. Time sync is very important for us, as it has to mactch database and all. Look forward to get reply on this.
