Resolving Host

Hi All,

My PC is randomly unable to resolve host names in IE or Chrome This issue occurs about every 20-30 minutes at which time I am unable to get to any website and all network access on the PC stops. I have scoured the forums of many sites and tried all the usual tricks (flush DNS, static DNS servers, static IP address and DHCP IP, and even a different 2 different routers with different firmware (stock and tomato). Here are few things I have discovered. If, when the issue occurs, I pull my network cable and re-attach it, the issue is resolved until next time. Same with disabling and re-enabling the NIC as well as a release / renew on WAN side of router After dealing with this for about a 3 days, I wiped and reinstalled Windows and the problem was resolved for about 3 weeks. Now it is back again. I am at my wits end and really don't want to reinstall Windows again. Any help is greatly appreciated.

BTW, this problem never showed up until I upgraded CPU and MOBO.

Win7 Pro 64bit
Gigabyte GA-z97x-sli MOBO
I5 4690k CPU

I will retest the pinging but I am pretty sure it failed as well. The DNS servers I assigned were a combination of Google's and my ISP's. I tested with only my ISP's, only Google's and then both...same issue.

Also, when the problem reared its head this time I was out of town and multiple Windows updaets were installed while I was gone. I uninstalled all of the ones that were installed on Tuesday however no change.

I will post back once the problem arises and I will test pinging as well as nslookup.

Thanks.

I didn't see anything mentioning that you've positively gotten the latest drivers for your NIC. Please tell us the make/model of your NIC as well as the driver you're using. If you're using the Intel LAN driver, the current version appears to be version 18.8. Gigabyte driver download page

NIC is listed as :

Intel(R) Ethernet Connection 1217-V

Driver is : 12.10.30.0


I will go ahead and uninstall and reinstall the one from the Gigabyte site. I have been suspected the NIC however I before the wipe and reinstall of Windows I did update the drivers with no change.

So far it has not happened this morning (at least not while I have been on PC which has been sparingly) but wil perform all tests ASAP.

Thanks for assistance.

Uninstalled NIC deleting drivers and downloaded from Gigabyte however it still installed version 12.10.30.0

Not sure where you saw the 18.8 version...

Thanks.

Update: I disabled my onboard NIC and installed a new PCI NIC (Intel PRO 1000 Server) and the problem is back again. Once again it takes down the entire network. No device on the network can access the internet. All devices show "Resolving Host" at bottome. Simply pulling the network cable from the PC nad immediately reinserting it cures the issue...WTF?



Please help!!

I don't think that is is the case because if I turn this particular PC off then no ther device on the network experiences the issue...it all stems from this PC...
