Windows 10: MSMPENG.EXE - Dns Queries

Hi,


I am unable to find why in some cases the antimalware (MsMpEng.exe) is doing dns queries (event 22 in sysmon). This does not appear to be consistent. I entered a url in Chrome and Firefox, Sysmon event log showed that these processes were reaching out (through dns queries) for the related IPs. MsMpEng.exe was out of the loop.


Why does MsMpEng.exe perform dns queries at times? Why is this inconsistent?

faster dns?

Just my opinion, I think you're barking up the wrong tree.
newtekie1 is correct in the assessment made.

And, also, once your system retrieves the resolved name, it stores it in your DNS cache and uses it.
So, basically, unless you or your system flushes the cache or the info changes, your system does not have to retrieve the resolved name from the remote DNS server.

What is the DNS cache?

If you wish to make a local dns server at home you can use windows server, linux, and other OSes.
Here is some info for RedHat, however, I doubt it will help your online gaming.

And, you may wish to do some reading up on the subject.
Here is a start... DNS Name Server Concepts and Operation. Set aside some time, as, it is a lot of reading.

You may just wanna do a little more testing (Gibson Research Corporation's Domain Name Speed Benchmark).
Pick the fastest and live with it.
You can use this to switch between DNS servers for testing or just picking the ones you like: Dns Jumper v1.0.4 by Sordum.net

You might want to look to other avenues to improve your on-line gaming experience.
EX: change your isp to one of better quality service, increase your speed, tweak your network settings, move, etc.

Good luck on saving that millisecond here and there.*Smile

 

DNS problems with router

A couple suggestions I have for you:

Update the firmware on the router. Maybe it's getting into a badstate, and a firmware update might fix it. Or if you're comfortable with it, install a custom firmware like dd-wrt. Just make sure its supported on your router first.

Change your DNS to: 8.8.8.8, 4.2.2.1. Might help.

If none of these work, maybe statically set your DNS on your PS3/PC to the IPs you listed, taking the router out of the lookup procedure.

Last option, is look for a new router.

 

dns probe finished no internet


Hi Oxide,

After some trial-and-error testing of all suggested fixes, which I found over the internet, here’re what worked for me to solve "DNS Probe Finished No Internet" issue and might work for you as well.

Method 1: Change Default DNS Address to Open DNS

Here all you have to do is change your default automatically obtained DNS server addresses to open DNS or Google DNS. To do this, follow below mentioned steps:

Step 1: Right click on Network icon located in Windows Task Bar Menu.

Step 2: Click on ‘Open Network and Sharing Center.’





Step 3: Click on Local Area Connection with whom who are presently connected and click onProperties.

Step 4: Select ‘Internet Protocol Version 4 (TCP/IPv4)’ and click on Properties.

Step 5: Now in newly opened windows, select the radio button that reads ‘Use the following DNS server address:’

Step 6: Now in the ‘Preferred DNS Server’ box type in 208.67.222.222 and in ‘Alternate DNS Server’ type in 208.67.220.220.

Step 7: Now check the box that says ‘Validate settings upon exit’ and then click on OK. That’s it.
