Configure a DC to be a reliable time source
Overview In a domain environment, by default machines get their time off the PDC Many times the hardware clock can fall out of sync or not really be in sync to anything. It is recommended to set the PDC as a reliable time source. How to do it quickly I have devised a set of command lines than can be put in a script to automate this. In this example, we will use the servers au.pool.ntp.org as they are the closest. On the domain controller which is designated as the PDC emulator, run the following commands below: net stop w32time w32tm /config /syncfromflags:manual /manualpeerlist:"au.pool.ntp.org" w32tm /config /reliable:yes net start w32time w32tm /query /configuration And that's it. If this still doesn't work you can run the following command to verify outbound port UDP 123 is open: w32tm /stripchart /computer:au.pool.ntp.org You should get a continuous output with a time offset. If you don't then outgoing communication v...
