Hi Marc,
I would personally use pool.ntp.org they have a huge cluster of NTP servers. It is one of the Largest NTP clusters and is the default NTP on almost all Linux distros(Hence free to use/No registration) and Is one I personally use.
To change the NTP server do the following.
Stop the time service
net stop w32time
Then configure the time source
w32tm /config /manualpeerlist:XXX.XXX.XXX.XXX,0x8 /syncfromflags:MANUAL /reliable:yes /update
The X's can be the IP address of the time server or the domain name of a time server such as
pool.ntp.org
Once the command above is done you need to start the W32Time service
net start w32time w32tm /resync
Next you need to sync all of your client PC's to the domain controller. You can do the following from the command line.
net stop w32time
w32tm /config /manualpeerlist:peers /syncfromflags:DOMHIER /update
net start w32time
w32tm /resync
Kind Regards,
Liam Kenneally
