In the Edit DWord Rate box, type 1 under Market price data, then click OK.

Just now oomph back and click on

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Parameters\NtpServer

In the honest pane, right-click NtpServer, then Modify, in the Edit DWORD Charge under Valuation Info type In the fitting pane, right-click NtpServer, then Modify, in the Edit DWORD Expenditure under Profit Counsel type the Kingdom Appellation Development (DNS), everyone DNS must be sui generis and you must append 0x1 to the boundary of each DNS denomination otherwise changes testament not receive effect.

Instanter click Ok.
