With a little registry play and the restart of a services I can not provide the right time to my SAN.

Here’s how to do it:

1 – Click Start, click Run, type regedit, and then click OK.
Locate and then click the following registry entry:
HKLMSYSTEMCurrentControlSetServicesW32TimeConfig

2 – In the right pane, right-click AnnounceFlags, and then click Modify.
In the Edit DWORD Value(Decimal) dialog box, under Value data, type 5, and then click OK.

3 – Now we Enable NTPServer.
Locate and then click the following registry subkey:
HKLMSYSTEMCurrentControlSetServicesW32TimeTimeProvidersNtpServer
In the right pane, right-click Enabled, and then click Modify.
In the Edit DWORD Value dialog box, type 1 under Value data, and then click OK.

4 – At the command prompt, type the following command to restart the Windows Time service,
and then press ENTER: net stop w32time && net start w32time
