Hi Freek, on windows there should be the "net time" utility which can synchronize system time. net time /help for further information. Hope this helps, Alessandro -------------------------------------------------------------- Hi, I have an oracle rac (10.2.0.3) configuration which runs on windows (windows 2003 SP2). On linux/unix I configure the NTP settings (to keep the time between the different rac nodes in sync) in such a way that, in case the time of the node is ahead of the time on the NTP server, it will not sync the time in one update but instead gradually slows down the time (stretching the seconds). Does anybody know how this must be done on windows?
