Windows Server-side large ports are dns.exe occupied by a workaround

When using the netstat command to view the server port, it is found that the server UDP port is open a lot, at least more than 1000, after careful and careful examination, online access to the following this solution:

Use the NETSTAT-ANB command to display the listener for each port on the server, because there is too much to look at, so you can only use:

Netstat-anb>c:\1.txt

command, save the output to the 1.txt file in the C packing directory, and look at it slowly.

After viewing, know that all these UDP ports are Dns.exe program monitoring, this server installed the DNS service, is it poisoned?

At the command prompt, enter:

CD C:

Switch C packing directory, execute:

Dir dns.exe/s/a

command to carry out a comprehensive search Dns.exe program, after n long, the system retrieved 5 Dns.exe, after retrieval, these 5 dns.exe belong to the system, without any problems, so as to eliminate the possibility of poisoning.

Then enter in Google: Dns.exe UDP port

The results shown for Microsoft's KB951748 and KB951746 patches will cause this problem to occur, as follows:

DNS Server Installation patch KB951748 KB951746 Increased number of sessions after communication

When the DNS server to the organization to find the new DNS server on the number of UDP sessions is amazing, uninstall the reload is not good, depressed for two days. This morning to Microsoft 800 call, but I give what number, unexpectedly technical support also want to verify genuine! Then to the Microsoft Community post, unexpectedly soon have a reply. Follow the above method to uninstall KB951748 and KB951746 patches, sure enough!

The above is the online method, but I looked for patches, did not find the above two patches, and then, I went to remove the Dns.exe this program (because this program occupies a large number of ports), one of which can not be deleted, is the process in use, to view the PID bit 1084, so to turn off the process, delete the Dns.exe, and then go to view netstat, found that UDP occupies a large number of ports disappeared. At this point, the problem should be solved.
