Ping.exe DNS Lookup method

Utility how ping.exe performs its domain name resolution as it does not use traditional port 53 UDP DNS lookup. I tried using Network Monitor 3.4 TechNet but couldn't find anything that seemed to do the trick.

Any help would be greatly appreciated.

Just another note the absence of any visible search in NetMon 3.4 is the same for the areas not cached.

Thanks in advance!

If your local DNS cache contains the resolved domain name so there is no need to query DNS server.

in all other cases, I think it uses the DNScache service for resolution of domain, that is if local cache is missing the field being ping IP address.

Try process monitor from technet

apply the filter for UDP only and you will see will demand UDP Port 53 so that ping an unknown host.

He will tell you even what type of program, and request that the user initiated.

  • Is it possible to change the behavior of the URL bar so that it performs a DNS lookup on the entry that is clearly not a website? (I want to search :)

    Chrome, for example, does not perform a DNS lookup if the entry is not a valid Web site, instead, it searches in the default search engine.

    I think that if the bar URL have behaved in a similar way, it would increase by many user experience. I really like Firefox and using it for a few years, but these are things that really annoy me as a developer.

    The one big flaw that I find in the Chrome version of manages the entrances to bar URL is that one cannot add custom Chrome of top level domains, which makes working with top level domain websites internal quite annoying.

  • Ping.exe usurps RAM; How to fix

    When I'm online ping.exe as shown in my task manager continues to use more and more RAM one I finally get insufficient virtual memory warning.  While my RAM is not huge it is used otherwise until the ping.exe takes longer.  I tried another registry cleaner and Registry Booster and have a subscription to McAfee actibe; I changed the security settings and pretty and all that I can find to fix and he continues to prevail.  How can I solve/fix/cure this situation?

    ' lo once again, Aziz.  Following my last submission, I think I can finally control my situation that included annoying "redirects" to websites, I had no desire to see.  I do not start in own State as the button to download the instructions for us droolers led to a path that only told me that the download was not available now, try later... and later... and later... ad nauseam.  I start in safe mode and signed as an administrator.  I then ran McAfee scan which found 15 cookies that had not been thrown into previous efforts with various cleaners.  As a result, when restart the c/f chkdsk safe mode, I had tried to make a different point of view finally ran... once for each time that I tried to let him go.  What finally did was to remove corruption from a file in the boot registry.  When it was finally started in normal user mode I noticed enough bit that the ping.exe (tcp/ip malware) consumed no longer massive amounts of my RAM or even obvious at all.  Also, I had stopped be 'redirect '.

    MalwareBytes's AntiMalware - no AntiVirus. ;-)

    Probably your best bet - flatten (wipe) the system and start from scratch.  You will need your most recent backup (your stuff, like your documents, photos, music, video, spreadsheets, databases, presentations, bookmarks/Internet favorites, e-mail contacts, serial number, proof of purchase/receipts, that may have been scanned in, etc. and so on...) and a good list of installed software and hardware specifications (I suggest Belarc Advisor running on the current system and print the results if possible) then you can get the drivers before or after installation.

    Of course, you will also need your multimedia installation product key/serial numbers and that go hand in hand.  In Windows XP - there is no way for me to know (without telling you) what level your installation CD is... so you will need to install the SP2 and SP3 after installing the operating system.  I would leave it disconnected from the Internet (physically) until it is at least SP3 and you have confirmed its firewall is enabled and, if possible, you have installed an antivirus application.

    For you, I suggest the eSet 32 antivirus (not more) - which costs ~ $60 every two years for private users.  Add to that the MalwareBytes full package which costs, if I remember, ~ $25 for life.

    Then, once the system * is * connected to the Internet (physically) - get hardware drivers installed for everything and the rest 100 + installed post-SP3 updates.  Then you can worry about all your other programs and restore your files LAST.

    Hello

    -Don't you make changes to your computer before the show?

    Ping.exe is a Windows core system file. It is a Microsoft signed file. The program has no visible windows.

    Some malware camouflage themselves as ping.exe, particularly if they are located in the folder c:\windows or c:\windows\system32. So check the process ping.exe on your pc, be it on the pest

    I suspect a malware problem. I would have you use the Microsoft Safety Scanner and check if the problem persists.

    Note: You may lose some data infected while the malware is being eliminated.

  • FWSM: rule on tcp/1089 breaks DNS lookups

    A weird problem this time...

    Yesterday, I added a rule to the ACL on an external interface to the FWSM (v3.1.1). The rule has been something like this:

    list of extended outside access permit tcp any host aaa.bbb.ccc.ddd eq 1089

    After that, we got complaints about visitors is not able to resolve DNS queries. DNS be within a zone demilitarized on the FWSM - they were not solve all requests, but I was able to ping the DNS.

    Removing the rule solves the problem.

    Someone at - he seen this before?

    If your access list uses groups of objects, you can see CSCse60868, where an ACL w/object-groups a change may cause corruption ACL. If so, the problem disappeared not because you deleted the new line in itself, but because doing so caused a re - compile the ACL (compensating for corruption).

    Looks like you are having network connectivity problems or if you connect to a network with problems.

    First of all, make sure that your computer is connected to a network with internet access with success, by checking the cable network (ethernet) - is - it connected correctly? If you do not use a network cable, make sure that your wireless connection is connected to the appropriate network.

    If you're still having problems after checking the physical connection, try to run Windows Network Diagnostics. Make a right click on the network of small size or icon wireless near the clock (bottom right of the screen by default), and then click "solve problems". This wizard will search for and attempt to correct any network, connectivity issues.

  • Why Ping.exe running so hard?

    My anti-virus does not like a virus - but when I try to stop Manager tasks 'finish the process' - it keeps jumping to the top and eat my memory - I need to remove it? What do you recommend?

    What you describe is probably related with the TDSS/Alureon rootkit. Kaspersky TDSSKiller might be able to remove it:

    It would be a good idea to run another utility anti-rootkit. GMER is good:
    I would also recommend two anti-malware utilities: SUPERAntiSpyware portable scanner and the FREE version of MalwareBytes Anti - Malware (not the Pro or the trial version!):
    What version of XP you are running (Home, Pro, or MCE)? What level of SP is in? If SP3, you have all the security post-SP3 hotfixes installed? Finally, if you use Adobe Flash, Adobe Reader or Java from Oracle (formerly Sun), you have the latest versions installed? If your system is not UP to date with all THE latest security patches, you will surely get infected again!

  • High load on the DNS lookups strange made BBNTD

    I don't know if there is a bug report area (I have to confess I always get lost on this site - between BB and Quest, but that's for another day), but I see some very crazy behaviors of one of my installations of BBPE. I'm still running v4.4 (access to builds more returned was one of my many problems with taken BB - a site for hours chatting with someone - again, for another day), but my config remained relatively unchanged for some time, but recently, I have been see a lot of testing side purple server will year it corresponds with a heavy load of CPU on BBNTD - almost 60% on a Server 2 processors with 3 GB of RAM. The server is 2008 R2 with all the patches. When I drilled down, I saw a large number of packets DNS targeting the DNS server (flooding the server DNS - something like 750 packets per second). Queries seem to be for a part of the name. All my internal machines are in the DNS netway.priv space, but queries are for y.priv and y.priv.netway.priv, again and again in order. The DNS server sends responses without a name such as one might imagine.

    I can provide the config files and wireshark capturing traffic, but there seems to be a parse error, perhaps for a nonprintable character or something. The last thing I did to the system was to allow and to start using the web - host configuration editor. This may have introduced a problem or it would be completely different.

    At the present time, my server is useless noctilucence, because it shows stale random tests more than actual errors. BBPE and BBBTF have been quite reliable, as I am unaware of any troubleshooting tools available to the attention of implementers. Is there a way to put BB server logging mode or debug? Can someone tell me how can solve this problem. I'm reduced to systematically change the bbhosts file to try to isolate the problem. I am trying to turn off all DNS queries for devices in the namespace my, using testip and no conn, but even if it works, it is not acceptable in the long term.

    Advice or guidance would be appreciated.

    Hi Jim,.

    I understand your frustration, but I've never seen that happen before (I thought at first, but when you bring DNS queries, then it was something new, at least for me). And as there is no ticket open with Quest (at least to my knowledge), it is difficult to debug without access or data from the facility.

    At this point, I strongly suggest an opening with Quest support call. If you have purchased licenses BBPE, you are entitled to it. This site is a community where it's more of the "how can I" or "where can I" type of questions. When it comes to questions like yours, if after one or two responses, the problem cannot be resolved, it is better to contact quest support (as I suggested). It will probably find its way to me. And I'll be happy to work with you to resolve the issue.

  • DNS lookup failed

    When I try and connect to the internet, an error pops up saying that the Web page is not available. When I troubleshoot the problem it comes up saying that the DNS server is not responding. I looked towards the top of tutorials on the internet to see if I can solve the problem that way, and they actually work, but only for a short period of time (about 2 minutes). These are the videos that helped me http://www.youtube.com/watch?v=q0FQzgAry0g http://www.youtube.com/watch?v=OqLDGA3j-tc , but they temporarily solve the problem. I use the server address that told me to use, but after about 2 minutes, happening at the broken DNS address which rises to 127. 0 0.1. It is very frustrating and I can't seem to fix it. Any help!

    Hi RhysMelville,

    Do you use wired or wireless internet?

    I suggest you clear the DNS cache and see if that fixes the problem. Clear the DNS cache forces DNS to query a DNS server rather than using the information stored in the cache.

    Follow these steps:

    a. click on the button 'start '.

    (b) in the search box, type "command prompt".

    c. in the list of results, right-click Guest and then click Run as administrator. If you are prompted for an administrator password or a confirmation, type the password or provide confirmation.

    d. at the command prompt, type ipconfig/flushdns

    e. then type ipconfig/registerdns , and then press enter

    You can also look at the suggestion of the following link:
