Block NTPServer (UDP 123)

$

Hi all,

I have setup on the GPO that NET server is disabled and I can see from the registry "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\W32Time\TimeProviders\NtpServer: Enabled = 0x0000"

But still my server offer NTP service to others "net time \\server" and also the port UDP:123 is available.

I want to keep the NTP Client on, so the server can keep time in sync (AD member server), but I don't want that my server is offereing the NTP for others.

Any idea?

(I try to make the server safe without firewall)
