Such a long title of error message, I got this error on the Win Server 2012, The server is running for more than 2 years and suddenly all my apps is hang.
The first things we want to check is what is the UDP Port is currently using there is 2 ways to check it.
1. Is using TCPView
2. Is using Command Prompt (netstat) it.
Open the Command Prompt “netstat -anob -p UDP > 20150414_1521.txt” It will save in this file.
We will see there is alot of list of “Dnscache” which is using PPID 3312
UDP [::]:49656 *:* 3312
Moving forward we want to know what is the PPID 3312.
tasklist /svc /fi “pid eq 3312”
svchost.exe 3312 CryptSvc, Dnscache, LanmanWorkstation,
Based on this article it said to turn off the LLMNR Listener, on the last comment
From what we capture the network traffic we saw that .48 is calling LLMNR destination 126.96.36.199 which is also state in this article:
To fix this issue I use the last article “Disabling LLMNR Causing Slow Network” and it work.
