Hello, I am trying to resolve a time synch issue which is resulted from a conflict in configurations that was a pre-requsit demand. Oracle describes in their documentation that in order to properly use W32Time, you must set MaxNegPhaseCorrection to 0. This registry setting will dissalow Windows to correct time backwards. The server we are using as an Oracle database host is a DL380 G7 server and it has a 'natural" time drifting of approximatly +0.1 ms every second which is ~8.5 seconds a day. (used w32tm /stripchart /computer:%PDC_Emulator% /dataonly) After a first forced sucessful synchronizing (set the time manualt to lag behind in 5 seconds and saw the time corrected by w32time), the next time a synchronization event occurs, I am getting Event ID 34 in the system log: "The time service has detected that the system time needs to be changed by 0 seconds. The time service will not change the system time by more than 0 seconds. Verify that your time and time zone are correct, and that the time source servername-fqdn (ntp.d|0.0.0.0:123->192.168.2.11:123) is working properly" The server running Oracle is a Windows Domain member. The Domain Controller running PDC emulator is synchronizing time properly with and external NTP. Anyone has any idea how to make the time on the server to move solwer? There is no problem in synchronizing the time forwards, but it is forbiden to synchronize backwads. -Yossi

Have you apply this resolution. http://technet.microsoft.com/en-us/library/cc733187(v=ws.10).aspx Thanks
