Not sure what is happening, but the time (EDT) on a W2008R2 server is consistently - and exactly - 5 minutes fast all the time. I've tried looking at the settings, even changed the time server it look to, but the time on the server, and therefore on the AD network, is always 5 minutes fast. Also running Exch 2010 on this box, so people who answer emails quickly appear to get "replies" earlier than their original messages! Any thoughts appreciated. Thanks.

Hello, is the DC with the PDCEmulator configured to use an external time source or hardware device(not domain member)? Or do you work on it with the builtin BIOS time?Best regards Meinolf Weber Disclaimer: This posting is provided "AS IS" with no warranties or guarantees , and confers no rights.

As far as I know, yes, external. I even changed the external time source to a different time server. And if I run a "clock" software on the PDC, even it shows me the time as 5 minutes fast - not only my local time - but also UT when it reaches out to an external time server. Very puzzling.

Hello, on the DC with the PDCEmulator FSMO run: w32tm /resync and check the event viewer for events about time sync and which time sourec is shown.Best regards Meinolf Weber Disclaimer: This posting is provided "AS IS" with no warranties or guarantees , and confers no rights.

When I ran it, it returned: "The computer did not resync because no time data was available." There was absolutely nothing about time synch in the event viewer.

Hello, in your network something is going not optimal. In your situation i would kick out any time configuration on the DCs first and start fresh. Then i would go on with the domain member servers and he clients. If you use VMs as DC disable the time sync to the host server. First make sure all machines are in the same time zone and that adjust daylight time settings are equal. Then go on with the reset of the time on the DC with the PDCEmulator FSMO: net stop w32time w32tm /unregister w32tm /register net start w32time Now configure it to an external time source: 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/ Make sure firewall port UDP 123 is opened. Now reset the time on the other DCs as already shown above and then reconfigure the time with: w32tm /config /syncfromflags:domhier /update After that you have to run: net stop w32time net start w32time And after they are working go on with the clients, also remvoe the configured settings and then run: w32tm /config /syncfromflags:domhier /update After that you have to run: net stop w32time net start w32timeBest regards Meinolf Weber Disclaimer: This posting is provided "AS IS" with no warranties or guarantees , and confers no rights.

Thanks - seemed to do the trick.
