Recently found that a lot of users of the server to send out a lot of traffic, after a check is basically UDP packets, basically can only determine the site is a program problem, but can not find the specific problems, so only to get such a palliative treatment does not cure the method, The method of the day mutual data technology is to use local policy to prohibit all UDP protocol communication, the following methods are as follows:

1, enter gpedit.msc in run, open Group Policy Editor

2, open the Group Policy manager, turn on the computer Configuration->windows set-> security settings

3, right-click-> All Tasks-> import policy on IP Security Policy

4, in the Browse window to select a policy to prohibit UDP protocol communication, open, in the end will share this strategy to everyone

5, the policy that we added in the right window is not yet in effect, right click on the assignment, and then see if your server traffic is down.

The above is my way to the server to send UDP traffic outside the processing method, however, this method has some deficiencies, that is, once the application of this protocol, then the domain name resolution will appear problems, sometimes lead to the generation of static page when the phenomenon can not be generated, when encountered this situation, only need to change the hosts file. Today's lecture will be here, days of mutual data technology http://www.idcs.cn contribution, I hope to help you friends.
