Time on Windows 2008 R2 DC incorrect and wont Resync

Hi Experts,

The time on single our domain controller running Windows Server 2008 R2 SP1 that holds all the FSMO roles has the incorrect time…its running about 3 minutes late and all the client computers have the same time so also incorrect.
If I run this command on the DC: w32tm /resync I get the following error message “The computer did not resync because no time data was available” I have tried to stop the time service, unregister it, re-register it and the restart the service but this made no difference. I have tried temp turning of the firewall on the DC also but still the same.

Any ideas how I can fix this?

is the server configured correctly as a time server and to use external source?

Check the Directory Service section in the event viewer and you should see warning messages related to W32time. This means your external time source is not configured and need to be.

Source W32time
Type: Warning
Event ID: 12

I have just tried the run the fixit program to setup Configuring the Windows Time service to use an external time source but dont think this has helped.

NTP server in the registry says: time.windows.com,0x1

Do you see any events in the event viewer which point to a time sync issue?

expand 'let me fix it myself' and verify the registry entries

on step 4, i use 2 or 3 servers from ntp.org

http://www.pool.ntp.org/en/

you can skip step 6 on the correction settings; i typically leave those at defaults and it works fine

I checked all the registry entries steps manually and all looked fine and i made no changes in the registry.
interestingly I just run w32tm /resync on the DC and it said "The command completed sussfully" and the time looks ok now. not sure why its started to work

Will just have to sort out the client next as running the same command on them disaplys the same error I was getting on the DC

Thanks for your help, issue has been resolved. Looks like the fixit utility did the trick. Clients appear to be slowly updating to correct time also. I had to run the re-sync command on some of them or stop and restart the time service.
