Why does a windows XP domain client default to having NTP server enabled?

  • 772

On a windows XP client that is a member of a domain, resetting the Windows time service to defaults (w32tm /unregister, w32tm /register) enables the NTP server on the XP machine itself.

(HKLM\System\CurrentControlSet\Services\W32Time\TimeProviders\NtpServer\Eanbled = 1)

It also says this in the MS docs on WTS registry settings here: http://technet.microsoft.com/en-us/library/cc773263(WS.10).aspx

The server shows as being enabled by doing a "netstat -a":

UDP XP-PC:ntp :

Why?

Is there any harm in disabling it?

    IF the XP machine is a part of the domain, it's going to pull it's clock from the DC running the PDC Emulator anyway. I don't think there is any harm with leaving it, or changing it if you really feel the need.

  2. Because if the computer time differs from the domain controller(s)'s time, domain login can fail.
