Synchronizing Time Server on the Domain
Now by default the Primary Domain Controller gets its time from the BIOS clock on the server motherboard. If this time is not accurate ALL the computers in the domain will have incorrect time and date settings.
I suppose you could down the server and reset the BIOS clock but why not just synchronize to an external time source?? The government has a pile of time servers available. Most of these are associated to the NIST or National Institute of Standards and Technology. They keep a compehensive list of servers at the following address: http://tf.nist.gov/tf-cgi/servers.cgi
Obviously pick your time zone for best results!!
The commands are pretty straight forward. Open a Command Prompt on your DC and enter this command
w32tm /config /manualpeerlist:198.60.73.8 /syncfromflags:MANUAL
Put in the IP address of the time server you want in place of the 198.60.73.8 above. You can add more than one server if you separate them with commas. Then you should issue this command:
w32tm /config /update
Make sure you get a 'completed successfully' message. The time will update on a interval between 64 - 1024 seconds. If you want to force an update enter this command:
w32tm /resync
Now everyone in the domain and all the servers should start showing the updated time, but only after each device goes through its timesync interval with the server. Give it a day or so.
