DNS Issue - Calling on a DNS "deep dive" expert for help with this problem RRS feed

  • Question

  • Got a doozy of a DNS problem to solve and need community help.

    Problem:

    XP SP3 Media Center Edition. Running on Dell Inspiron E1505. Customer machine brought to me. Complaining of running slow and can't connect to Wifi. Fixed Wifi problem. They had tried to install one of the Fry's Wireless N USB adapters and the install failed taking down the internal broadcom driver too. Fixed those problems and got Wifi working fine. Wired network connects as well. All LAN opeation was then working fine. Found that they had installed not one, not two, not three, but four different Anti-Malware solutions which were all running along with Windows Firewall at the same time. No wonder the machine was running slow. So, one by one I removed McAfee Security Scan, Norton Security scan, PC Tools, remnants of an old Trend Micro install that came with the original config from Dell, and Webroot with Spyware Doctor. My intent was to put Norton 360 on it after cleaning it up.

    Well, I never got the chance because after all the cleaning up and rebooting, suddenly found that DNS cannot resolve names anymore. I've isolated the problem to DNS and not to the network stack itself.

    1) Ipconfig shows full and proper config by the Router. I've used both the customer's site network/Router as well as my own at my shop. Problem is not with LAN/WAN infrastructure or config.

    2) Ping works to any IP address whether LAN or WAN.

    3) Nslookup works. Can lookup Google.com or any other host and it returns proper IP address(s).

    4) Cannot ping any host by Name. Gets usual message "Ping request could not find host xxxxx. Please check the name and try again". Example: cannot ping Google.com but can Ping IP addresses returned by Nslookup. Can use IE to navigate to Google's website by using IP address. By URL fails even though I have Google.com entered in local HOSTS file. See below.

    5)  Cannot even Ping Localhost by name. However, can Ping IP of 127.0.0.1 and it is successful. Made sure HOSTS file contains entry for IP and Localhost but still no Love. Also, tried putting Google.com and IP in HOSTS file but fails too.

    6) ipconfig /displaydns shows that the cache contains only the entries from the HOSTS file and no others since it is not receiving any resolved Host Names. Has both the A and PTR records for Localhosts. Ping by Name still doesn't work. Tried rebooting, flushing, etc. No Love.

    7) Used Netsh to reset both Winsock and IP but to no avail. Also tried uninstalling TCP/IP and then re-installing the protocol to no avail.

    8) Have used Sysinternals Process Explorer and other tools to verify that the Dnsrslvr and Dnsapi DLL's are loaded and functioning. Not completely proficient with those tools though so I might be missing something.

    9) Have used Autoruns to find and eliminate any startups being loaded by Registry keys for missing files. There were a number of those. Some left over by the uninstalls of the old Anti-Malware ____. Also, downloaded and used the tools from the named Anti-Malware vendors above to do a deep un-install of their various products. I did this before using Autoruns to get rid of the rest of the remnants.

    10) Can use Windows Explorer to navigate machines on the LAN without problems because of NETBUI helping out. If only DNS was available it would fail.

    11) I've tried rolling back the system to System Restore points available prior to the customer bringing the system to me. Only one of those Restores actually finished (DNS problem still there). The other Restore points fail to restore.

    12) In short, I've tried everything except re-installing XP as either a Repair or full replacement. Oh, I've also replaced the Dnsrslvr.dll and Dnsapi.dll files. No Love. I don't think the problem is with corrupt or missing files. It must be related to misconfigs in the Registry that are preventing DNS and the networking infrastructure from getting, accepting and caching resolved names properly.

    13) Help if you can. Thanks!

All replies

  • First start by clicking on start > run

    Then enter the following

    "ipconfig /flushdns" then press enter

    "netsh winsock reset catalog" then press enter

    "netsh int ip reset reset.log"

    Then reset computer. What we are doing here is clearing the DNS resolver cache. sets catalog to factory defaults and dns settings to factory settings.

     

    If this works let us know. If not that also. Hopefully this helps

  • Thanks for the reply FirstKnight,

    I tried the reset for Winsock and IP quite awhile back in my debug process... to no avail. I also tried once again after reading your reply... still to no avail.

    I thought I was pretty good at IT until I ran into this problem. This one stymies me. I'm convinced that it has to be something corrupted in the Registry that is preventing the resolver from completing it's query/cache process. As I mentioned in my writeup, I can manually make an entry in the HOSTS file (Google.com with associated IP) and the entryt shows up in the DNS cache (ipconfig /displaydns) yet I cannot Ping Google.com by name (only by IP address) nor can any other utility reach Google.com by name except nslookup. If I try to Ping any host by name, the request fails immediately. So based on that, I know that the problem is defintely local to my machine. I've also (now) connected this laptop to three separate wired networks in different locations with three completely different DNS server configurations.

    Still at ground zero on this one.

    Thanks again

  • Wow

      last time the solutions I suggested work for me. Instead of using netdiag what is contained in the msinfo tool report.

    Click on start > run >"msinfo32" then ok.

    expand components >network > protocal

    If this doesnt match this list reinstalling the winsock component should fix your problem.

    • MSAFD Tcpip [TCP/IP]
    • MSAFD Tcpip [UDP/IP]
    • RSVP UDP Service Provider
    • RSVP TCP Service Provider
    • MSAFD NetBIOS [\Device\NetBT_Tcpip...
    • MSAFD NetBIOS [\Device\NetBT_Tcpip...
    • MSAFD NetBIOS [\Device\NetBT_Tcpip...
    • MSAFD NetBIOS [\Device\NetBT_Tcpip...
    • MSAFD NetBIOS [\Device\NetBT_Tcpip...
    • MSAFD NetBIOS [\Device\NetBT_Tcpip...
       If there is more then ten entries, there may be additivity proxy software installed. If netbios there will be 17 entries. And the Microsoft automatic troubleshooter is also listed here. Wish we had this when Sp3 first came out.

  • OK. Back from Christmas break and back on this problem...

    Prior to posting my problem on this forum, I had previously reset Winsock, re-installed TCP/IP, did all the usual debugging that I knew how to do, etc. etc. with no success as far as solving this problem.

    I've even run XPNetdiag and the Support Tools version of Netdiag. XPNetdiag shows that everything passes except DNS name resolution. NetDiag does not reveal any errors.

    Per your suggestion, I went ahead and tried resetting the Winsock catalog again. DNS Still not working.

    There appear to be 34 providers in the Winsock catalog (list obtained by using MsInfo32 or by running the netsh winsock show catalog command). Nothing unusual looking (to me anyway) in the listing.

    I have posted the results below (abbreviated because the entire text would not post):

  • Hi,

    I had an issue similar to this once. I eventually uninstalled the local area network adapter through device manager and rebooted the machine to resolve the issue. So for example enter device manager, locate the local area network adapter, right click the adapter and select uninstall. Upon rebooting the machine the adapter will re-install automatically. Does the issue occur when using both wired and wireless connections?

    Kind Regards.

  • Barry, thanks for helping out.

    Unfortunately, the problem is strictly with DNS. Both wired and wireless can connect to the Router and get their respective configurations via the Router's DHCP service. LAN communication works OK as long as NetBt is working.

    I tried uninstalling the wired adapter driver, rebooting, and it re-installed the driver on reboot. Still no Love though. As I said, the hardware and networking is all fine. It's strictly related to DNS.

    I can ping any IP address be it localhost (by IP 127.0.0.1), LAN, or Internet (only if I know the IP). However, I cannot ping any host by name be it locahost (by name), LAN or Internet. Anything that requires a DNS lookup will not work. Even if I have that entry in my local HOSTS file. And, anything I put in the local HOSTS file shows up immediately in the DNS cache which I can check using ipconfig /displaydns.

    I can get to Google.com by using the IP address in Internet Explorer. But, clicking any link (which requires a DNS lookup) fails.

    So, that's why this is weird. Everything seems to be working yet DNS fails to actually query and cache any lookups (even though the local HOSTS file will populate the cache it is also not being used to translate the proper host name into it's IP address for use in connecting to a host).

    Still stymied.

  • Have you tried disabling the service "DNS Client "?
    Wednesday, January 5, 2011 1:14 AM
  • "Disabling"?

    Don't you mean "enabling"?

    DNS name resolution depends on the DNS client service in order to function correctly.

    fwiw - with or without the DNS client service running, the posted DNS issue still exists.

    Should give the proper fix the netsh with options would be my first suggestion to reset the arp cache. 

    Unless you have a firewall installed or dns service disable. Hopefully this is the solution.

  • Last time I saw a similar problem to this was related to malware dug deep into registry and found it it was from installing and uninstalling all the pretend anti malware and toolbars from ie.  couple things to clear up & also  check as troubleshooting:

    1. This is not a DNS server or a router problem, this is a problem within the machine, the fact that u test it out with two different routers   proves this. (I am talking to myself here)

    2. In i.e: Go to tools > options > Connections (make sure everything looks normal here > Lan settings > "Automatically detect settings" is checked on and no other proxy server should be in there.

    3. do an msconfig and make sure no other services, or apps are starting up, you may want to do a diagnostic startup using msconfig,

    4. does the problem happens in safemode with networking?

    5. there is a command for winsoc /reset all, don't remember exactly what it is but it seems like you may have tried this all ready, just wanted to make sure u tried 'all" part.

    6.  look at the secondary dns server on ur nic

    7. do a registry check, or just check all the registry hives connected with the nic interfaces, sometimes malware hardcode dns servers into registry ,

    8.  install procmon and wireshark on the machine and take a look at the packets.

     

    I hope this helps.

  • I'm pretty confident too that it is a registry problem. Just not sure exactly what it is.

    1) You are right. It is not a DNS "Server" problem. It is a DNS resolution problem most likely with the Client. I've already done the usual checks to make sure the Service is running etc. The fact that Nslookup runs OK tells me that the DNS service is functioning but something else is causing it to fail when requesting/processing DNS queries under certain circumstances such as through Ping and thru a web URL lookup. Heck, the machine cannot even resolve the Localhost name which is the Loopback interface of 127.0.0.1

    2) It's not an IE or browser problem either. Already checked all this out. The problem is at a much lower level. See #1.

    3) Nothing there causing any problems either.

    4) Problem happens in safe mode as well. Precludes anything in #3 being the culprit.

    5) Already tried the IP and Winsock resets. Documented in posts above in this thread.

    6) Not the DNS Server config either. Lower level problem as stated.

    7) This one will take some insight from someone who knows what to look for. I've already run the Symantec branded version of Registry Mechanic (Norton Utilities) nine ways to Sunday and still has not resolved the problem.

    8) Doing so will likely only tell me that the protocol related packets are not being sent/received. Won't (as far as I know) lead to the source of the problem. Maybe will. Maybe won't.

    Thanks for your help.

  • I won't argue the  rest but for #8, you may want to give it a try as Procmon can tell you what registry keys are being accessed and if there are any permission issues.
