Server is 2008 r2 it seems to not keep time and the network drifts due to this. I have specified in the registry below 2 external time sources, see in the registry below bolded. What am i missing to keep time?

Hello, is this in a domain and this is the PDCEmulator? Are this physical machines or virtual? If the latter are the integration tools or VMware tools or other set to NOT sync the time with the host machine?Best regards Meinolf Weber Disclaimer: This posting is provided "AS IS" with no warranties or guarantees , and confers no rights.

It is a Physical box and is DC holding all fsmo roles for the time being.

Hello, well, i never use the registry for time configuration since 10 years, only if special settings must be made. In your case with problems i suggest that you start from scratch using the w32tm command line tool only. Therefore run the following commands: net stop w32time w32tm /unregister w32tm /register net start w32time Now go on with: w32tm /config /manualpeerlist:PEERS /syncfromflags:manual /reliable:yes /update Please set for PEERS the time source as listed above, either with it’s ip address or DNS name. If more then one is needed separate them with a space in between and don't forget the quotes: "time.domain.com time1.domain.com" Internet Time servers you can find here: http://www.pool.ntp.org/ More details in: http://msmvps.com/blogs/mweber/archive/2010/06/27/time-configuration-in-a-windows-domain.aspxBest regards Meinolf Weber Disclaimer: This posting is provided "AS IS" with no warranties or guarantees , and confers no rights.

Meinolf, My time seems like it is working somewhat but drifting. right now it is about 30 seconds slow after a reset 5 days earlier, PC's are getting time from the server, the server is drifting however! Your syntax corrected would be w32tm /config /manualpeerlist:"24.56.178.140,0x01 198.60.73.8,0x01"/syncfromflags:manual /reliable:yes /update Is this correct? What would cause the drift in synchronization? Here is a great link for Time in the US, http://tf.nist.gov/tf-cgi/servers.cgi It also give status of them. What would be a better time sync, one of the nist.gov sites or one of the ntp.org sites 0.north-america.pool.ntp.org 1.north-america.pool.ntp.org 2.north-america.pool.ntp.org 3.north-america.pool.ntp.org? If I run w32tm /monitor I:\>w32tm /monitor Data2.HDH.local *** PDC ***[[2002:aae5:b0a::aae5:b0a]:123]: ICMP: 0ms delay NTP: +0.0000000s offset from Data2.HDH.local RefID: 'LOCL' [0x4C434F4C] Stratum: 1 DCSERVER.HDH.local[170.229.11.2:123]: ICMP: 0ms delay NTP: +153.7736250s offset from Data2.HDH.local RefID: (unspecified / unsynchronized) [0x00000000] Stratum: 0 w32tm /resync Sending resync command to local computer The computer did not resync because no time data was available.

Meinolf, I did this as you suggested and nothing has changed. net stop w32time w32tm /unregister w32tm /register net start w32time w32tm /config /manualpeerlist:0.north-america.pool.ntp.org,0x01 1.north-america.pool.ntp.org,0x01 2.north-america.pool.ntp.org,0x01/syncfromflags:manual /reliable:yes /update I ran this..... w32tm /resync /rediscover Sending resync command to local computer The computer did not resync because no time data was available. w32tm /query /status Leap Indicator: 0(no warning) Stratum: 1 (primary reference - syncd by radio clock) Precision: -6 (15.625ms per tick) Root Delay: 0.0000000s Root Dispersion: 10.0000000s ReferenceId: 0x4C4F434C (source name: "LOCL") Last Successful Sync Time: 6/27/2011 9:35:18 AM Source: Free-running System Clock Poll Interval: 6 (64s) I have also tried this below and it didn't work.

I have removed the time settings in the default domain controllers policy , there are no time settings in the GP. On PDC Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\w32time\Config, and verify that the value of AnnounceFlags is 5. Expand TimeProviders key, click NtpServer, and then ensure that the value of Enabled is 1. On the second DC Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\w32time\Config, and verify that the value of AnnounceFlags is 0x0000000a (10). Click Parameters under the w32time key, and verify that the value of Type is NT5DS. Expand TimeProviders key, click NtpClient, and then ensure that the value of Enabled is 1. After that, restart the W32time service on both DCs, run w32time /resync /rediscover on the second DC and check the result. w32tm /resync /rediscover Sending resync command to local computer The computer did not resync because no time data was available. w32tm /query /source Local CMOS Clock Still no joy, what am I missing?
