Usually when Windows is discussed, it's in regards to a Linux interaction. For example, a problem running a Windows guest under Linux virtualization, or Windows connecting to a Linux server. There are hundreds of Windows support sites, if you are just having a Windows problem.
I shouldn't, but I would show my good intentions.
Just turn off NTP (Network Time Protocol). It includes any internet time synchronization!
And next time do your homework, before you would post on any forum and learn to read with understanding - it is LINUXquestions and not WINDOWSquestions!
Next time before you would ask about anything what have anything to do with IP ports type in google: tcp udp ports list and go to wikipedia link - it is actually rip off from IANA!
And, if would to use any server OS learn something about networking, IP, TCP, UDP, ports etc. 123 UDP is registered (as every 0-1023) and IANA put NTP on it really long years ago!
P.S. it is not flood! I can see that you didn't try to find what is it and why it appeared in first place! NTP is connectionless (rather obvious - it is UDP) and you simply register with "master" and "slaves" connects with you to synchronize your time, after completing this part you will become one of "slaves" as well - that is reason for high number of packets - you get your time and then you provide it to others. Eas, isn't it?
P.P.S. I read RFC for NTP years ago and simply gave him principles not specification, if he want to know how exactly it works, he can read NTP RFC and even thought I have this RFC on my server, I won't be looking for it - for me extending or refreshing this knowledge is pointless.
