How to: Configure Windows Server to query an external NTP Server
Step 1: Info
This is generally performed on DCs in an Active Directory domain. Then all workstations use AD to get time from the DCs. This could also be used on a non-DC windows machine to be your NTP server for your network that you point to for all of your switches/routers and various other devices.
Again, it doesn't have to be a DC, but it makes sense for it to be, as it's not very resource intensive.
Step 2: Elevated prompt
Open the command prompt as administrator.
You could also use a PowerShell prompt instead of command prompt if you want.
Step 3: Stop the time service
net stop w32time
Step 4: Set the manual peer list external servers
w32tm /config /syncfromflags:manual /manualpeerlist:0.us.pool.ntp.org,1.us.pool.ntp.org,2.us.pool.ntp.org,3.us.pool.ntp.org
Step 5: Set the connection as reliable
w32tm /config /reliable:yes
Step 6: Start the time service back up
net start w32time
Step 7: Test the configururation
w32tm /query /configuration
and
w32tm /query /status
