Enable NTP

Check to see if the Windows Time service is enabled in Windows services, by right clicking on My Computer and then left clicking on Manage.
Then, click Services in the left pane, and scroll down in the right pane and look to see if Windows Time is listed.
If it is not listed in the Services, enable it with the following command from a command line window by typing:

C:\W32tm /register

Configure NTP servers in the registry, by editing this registry key using regedit:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Parameters

Edit the NTPServer key giving it the value of:

0.us.pool.ntp.org 1.us.pool.ntp.org 2.us.pool.ntp.org 3.us.pool.ntp.org,0x08

These are the standard client NTP servers for the U.S. The 0x08 tells the Windows Time service to run in client mode.
