installed / uninstalled / now my dns is having issues!

[chupakobra]

I rencently had someone come in and tried to setup my computer with wingate vpn. realizing this wasn't what we needed I uninstalled it from my computer and now have intermittant loss of dns services. I am running Windows 2000 Professional and connect to the internet via a netgear rp614v2 router w/dhcp. This problem does not disconnect my computer but rather stops it from resolving dns names to ip addresses. I also noticed in the event viewer the following error...

Event Type: Warning
Event Source: dnscache
Event Category: None
Event ID: 11050
Date: 3/10/2004
Time: 5:59:57 AM
User: N/A
Computer: DEVBOX
Description:
The DNS Client service could not contact any DNS servers for a repeated number of attempts. For the next 30 seconds the DNS Client service will not use the network to avoid further network performance problems. It will resume its normal behavior after that. If this problem persists, verify your TCP/IP configuration, specifically check that you have a preferred (and possibly an alternate) DNS server configured. If the problem continues, verify network conditions to these DNS servers or contact your network administrator.


I can usually get it working again by having Interet Explorer use a proxy server and then switching it back to no proxy but that doesn't always work.. also rebooting my cable modem and router seem to have no effect. I use the vonage phone service which never has a problem. Also I tried leaving another computer on connected through the same router and never saw the same problem. I've tried different cables, tried differnt network cards, and just about everything else I could think of.. WHAT THEN MIGHT IT BE? I've been through every setting and double checked everything I could.. I refuse to believe that I need to format my computer just because I uninstalled software that was doing nothing that I know of..

Also I believe that more then 1 version of wingate might have been installed at the same time. the person who put it on had no clue about networking. And until now I thought I did but this problem is baffling me!!!

Does it have anything to do with the fact that my cable line lease expires every 12 hours and sometimes changes ip's?

PLEASE someone tell me how wingate might have caused such a problem and more importantly how I might fix it..

Have you tried system file check? I had one piece of network software corrupt one of my system files on uninstall which gave me intermittent network service.

start > run > sfc /scannow

BTW you will need the os cd in the drive

The first thing to check would be for the presence of WinGate drivers. You are using Windows 2000, so in the <windows>\System32\drivers folder, check if there is anything called "qbikhk2k.sys". If that file is present, your uninstall in all likelyhood experienced problems.

Also double check in the normal installation folders for WinGate (<program files>\WinGate) to see if there are any files that were left behind. From the sound of it, it is possible, especially if someone installed multiple copies, etc. as you indicate someone did.

Then, check the routing tables to make sure that they are correct (Should be) and also double check that the Qbik RIP client has not been installed and is running (This will be in Services, under computer management)

I just can't seem to fix this. I tried to run sfc /scannow only to find that neither of the 2 win2k cd's I have are being detected. Is there a list of files so that I can manually go in and pull them off the cd-rom?

I found qbik drivers and stuff running all over the place. I went into drivers and selected to "show all" and was surprized to see many other qbik references which I uninstalled.

Here is my routing table print out.. does this look right??

Did you check for rip2client.exe running?

[Pascal]

Your route table looks good. Once you've removed all the Qbik references, I'm assuming that didn't resolve the problem. If you run the check again, are they still showing up ?

Secondly, from the command prompt, run a netstat -an. Is there anything listening on port 808 ?

Did the time of that event log (DNS Client) coincide with a DHCP Release / Renew ?

You haven't yet indicated if the RIP v2 Client was / is installed. Is that the case ?

[chupakobra]

I don't see rip2client.exe running or existing anywhere on this computer.


Nothing is listening on port 808.


The dnscache event log looks like it is triggered every 3 hours or so. I am able to ping the ip address of the dns and the dns backup servers so why I can't connect to them is a mystery. Other people connect to them fine to the best of my knowledge.

And I'm not seeing any remaining qbik references anywhere.

This is distubing that some little problem can hide so well. It just seams so random. I thought it was when my ip changes or when the lease ends and gets renewed, and it still could be, but it sometimes seems more frequent then that.

What you have described is the exact same problem I have had with Wingate. I can ping out on the internet, but I can't resolve addresses!!! What is going on !
