This Dns clinet error problem haunts me. Is there a real fix?

[Samson]

Your above screenshot looks correct to me....

I'm out of ideas J, 

Your best bet is asking with your router manufacturer and or your ISP, I can't imagine you are the only person in India using that model and that ISP, someone must have a solution, and I reckon that is your best route (sorry no pun intended  )

Hi, Boggins,
                      Two things seems to have fixed the problem of rebooting of modem at logon.
                       The first thing i noticed was when i restart the computers, all  the registry handles except, the avastsvc.exe isclosing normally. I thought that this has to be fixed. I had copied a kill  program bat, and renamed as ps1, powershell and copied the same in to the windows \system32\tasks.. I will give the exact location in the next post.
Then i followed this link and created a dword key and assigned 1 as the value .
Now, i do not find the behaviour of loss of dsl connection and reconnection.
I tried all kinds of search, and then found , it would be with the dhcp process.
Just found this topic by chance and did the same. Still, i do not know, it is a fluke or actually fixed the matter. Let us wait for some more time on this.
But, i do not know, whether the powershell script, ordinary commands bat file , renamed as ps1 is executing or not, but i did find that there is no more avast keeping open handles in registry and also the dls light is not blinking.
Now the ipconfig /all gives the following details:
Boggins , samson, How the pc becomes domain is still a mystery for me
I only installed windows operating system and not server operating system .
I tried to change the homenetwork settings for a single computer, but on next reboot, it gets back to business computer. still a mystery.

Hi, Is there any way to know, whether the powershell script has actually run or not, as could be seen from task scheduler history tab

[jraju]

Hi, The problem is back again.
               Will contact the ISP.
                   sub query: When i log on to computer , the computer just boots in to desktop without any alert of user.
                   But when i log off , it shows my computer user name, (the name we give when we install the OS) shows up. Then , which account the computer logs on noarmally?
                   If the computer has one user, will it show on log off and on session? or is it a different account? pl

[Boggin]

I've lost track of what you have done with this machine or what the problems are, but there are steps in this article which should help you to get rid of the Domain name.

Just use the first 6 steps unless you want to have your desktop PC and laptop in a Home Group.

https://social.technet.microsoft.com/Forums/ie/en-US/c87f817c-ac07-43b2-892b-066a21ef2569/how-do-i-remove-personal-pc-from-old-business-domain-to-join-windows-7-home-network?forum=w7itpronetworking

What does an ipconfig /all produce on your laptop as a comparison ?

[Samson]

J, I noticed that your PC name is "sarochan.chandru"

See this https://www.lifewire.com/naming-rules-on-windows-networks-818238

Especially...."Avoid special characters in computer names. Do not use any of these characters when naming Windows computers: / \ * , . " @"

You have . in your PC name, and, including the . your name is over 15 characters long, also lower case. So try

SAROCHANCHANDRU

Long shot I know, but I think we are already in that territory. It seems  possible as your PC name has been split at the . to give this from ipconfig /all


 Host Name . . . . . . . . . . . . : sarochan
 Primary Dns Suffix  . . . . . . . : chandru

Which is what is giving this whole "domain" issue.

EDIT 21st Feb....

Do you have the latest Realtek PCIe FE Family Controller driver 7.115 ? released 23/1/18

http://www.realtek.com/downloads/downloadsView.aspx?Langid=1&PNid=14&PFid=7&Level=5&Conn=4&DownTypeID=3&GetDown=false

[jraju]

Hi, Samson, Yes it is the latest version as per your link.
I have also changed the name , but still the problem persists.
The Dns client error id 1014 is the only window error showing at which time, i see the dsl light blink and establishes the reconnection.
Samson, Is it normal, if you restart, the modem also will reboot? I mean, the ethernet cable attached to the computer is getting disconnected when shutdown and connected while the course of booting. Is that correct? So, if you restart the pc, the dsl is also disconnected? Are my assumptions not correct?
If so, the restart will automatically cuts of the ethernet connection and reconnects, is it ?
I am yet to visit the link boggin has given and try those .
But i think, i have exhausted those already.

[Boggin]

When you shut the computer down, it is normal for the Ethernet light to go out on the router and come back on when you switch the machine back on, but your DSL light should remain on.

I don't have a DSL light as such - mine is for Broadband and having checked, your WAN IP address is your ISP's external address.

See if removing the Domain name gets rid of that 1014 error.

[jraju]

Hi, Boggins,
                      Domain.name is the default settings , as SSID Dlink. We normally assign those things. The next try is disabling ipv6, which is not yet been given by my ISP. I first disabled in ipv6 network adapter settings. But still getting fe.. ipv6 in some ipconfig /all details . So, i went to the registry and replaced the disabled components value to FF dword value, in the HKLM,system, currentcontrolset, services, tcpipip6,parameters GUID.This is given by msoft article to disable fully the ipv6. I enclose the details , now. Whenever, i run the ipconfig /release i use to get fe.. in the release command. Now it shows as blank.
Is there any clue, how to find whether My isp is actually shifted to ipv6, or combining both ipv4 and ipv6?
When i go and see the dns settings, there was a note, that it is for dhcp relay and hence i assume that it is a extra page and having nothing to do with the working of network. When i just leave it, the default dhcp relay settings is obtain address automatically, and the status shows my ISP server address. I checked that.
still puzzled at the dns error 1014. I tried all sorts of tricks
                         Is any wireless , default enabled by us in the wireless configuration , be the cause?
I will try to just remove the error 1014.
I just noticed that the bottom of the modem is somewhat heat? bearable?
strange error:
Name resolution for the name _ldap._tcp.dc._msdcs.domain.name timed out after none of the configured DNS servers responded.
This is the only error reporting. I do not have any server, as the fix for this is related to server OS

                             

[Boggin]

Routers do tend to get warm/hot depending on the make & model as to how hot they get.

I would change those registry settings back to the way they were - not sure if that is why you are getting that ping result on google.com

Do you get a reading when you ping yahoo.com ?

You can check if your ISP is using IPv6 by going into the router - my ISP's routers have always shown that as disabled and I have it unchecked in my computers, but as you can see, my ipconfig /all still gives it a form of address.

As I'm using Win 10, I can only use wireless or Ethernet, so in this instance on Ethernet, wireless shows as disconnected.

Ok, i will try to revert back by SR.
Ping yahoo.com gives correct results with no packet loss
One more thing.
I try to give a domain.name, to which i am getting a error, which is related to the ldap...errors i posted .
My query is i am not using a server, but getting kind of server response error, how. I enclose the error i am getting if i change my workgroup as domain and name say, abc.com
dcdiag.txt at c:windows\debug\dcdiag.txt is given below
The following error occurred when DNS was queried for the service location (SRV) resource record used to locate an Active Directory Domain Controller (AD DC) for domain "abc.com":

The error was: "DNS name does not exist."
(error code 0x0000232B RCODE_NAME_ERROR)

The query was for the SRV record for _ldap._tcp.dc._msdcs.abc.com

Common causes of this error include the following:

- The DNS SRV records required to locate a AD DC for the domain are not registered in DNS. These records are registered with a DNS server automatically when a AD DC is added to a domain. They are updated by the AD DC at set intervals. This computer is configured to use DNS servers with the following IP addresses:

192.168.1.1

- One or more of the following zones do not include delegation to its child zone:

abc.com
com
. (the root zone)

Hi, Boggins and samson,
Please see my post 51. Why it is showing as business and not home pc in the settings. I change it, but it never changes , when i open the network id in ocmputer properties.
Is it normal? or shown as default always, whether we change it or not in the radio buttons.
How could i know that it is not business having many computers, as i am having this annoying _ldap error always on logging .EVent id 1014. That error is related to domain.
I had been to the ISP's Dslam office and met the staff concerned , and checked my configuration. It was all correct except one settings, that pppoe protocol should be in a kind of bridged mode, which i have disabled.
I will try to say, exact mode as , i had to reset if i have to see the menu.
i checked with his computer and on restart, there was no cut of dsl connection and reconnection.
This -ldap server error is annoying me too much, as there is no settings fault .
He says, that by not selecting  the bridged mode, i was getting connected thro antenna of the modem thro wifi, even though i have ethernet connection.
He says, mere selection of PPPoe protocol would not give internet connection at all if it is just a modem without wifi.
I do not know what to say. Is it possible.
Now i have configured with him, and checking on my pc, it is disconnecting still
Since it is during the boot, i enabled boot log in msconfig and i am attaching herewith the log file in enclosed file
Could you suggest anything wrong. it shows some drivers did not load...

[Samson]

Hi, Boggins and samson,
Please see my post 51. Why it is showing as business and not home pc in the settings. I change it, but it never changes , when i open the network id in ocmputer properties.

Try method 2 here and see if it will allow you to change from "Business" to "Home"...
https://answers.microsoft.com/en-us/windows/forum/windows_7-networking/unable-to-change-network-id-from-business-to-home/3b7a31d3-236f-4aa6-90c1-25d509d70a06

He says, that by not selecting  the bridged mode, i was getting connected thro antenna of the modem thro wifi, even though i have ethernet connection.

Based on that, I don't think I'd have much faith in that tech guy

[jraju]

Hi, I already tried that . I have done that but the radio button shows my network id as business, even after reboot.
                       Is that a clue for the domain, dns problem?
                           What is your status of the same in the radio button, samson?

[Samson]

Mine is set for Home.

Can we sum up? Are you still getting internet disconnect when starting your desktop? This would explain the dns server timeouts error.

What happens when you start the laptop on wifi, does your router disconnect then? Disable wifi on the laptop and connect via ethernet...using the same cable, plugged in to the same port on the router. what happens then?

[jraju]

Hi, Samson,
                            there was no problem when i just power on the laptop with wifi in laptop enabled. After that, i disconnected pc's ethernet and connected to laptop and disabled the wifi on laptop. There was no problem at all. Not even a blink on the green lights of internet and dsl.
                          It was only on my windows 7 ultimate pc, that i get this problem. Computer is said ot be logged to user domain instead of active directory, of which term i know nothing. When i issued set user command on elevated cmd, i get user domain
Microsoft Windows [Version 6.1.7601]

C:\Windows\system32>set user
USERDOMAIN=sarochan
USERNAME=chandru
USERPROFILE=C:\Users\chandru

C:\Windows\system32>
So, is it in logging account, the problem arise, i do not know.
I also attempted a new command never heard before, gpresult -r.It gave so much details, can you say anything.

[Samson]

I can't help with GP log, that is above my pay grade 

So from your test with laptop we know that the router and cable are OK.

It is up to you, but if it were my machine I would try uninstalling and then reinstalling the network adapter (Realtek PCIe FE) and then reinstalling it and see if that clears everything so that you can set it up afresh.....BUT see what others (well Boggin) suggest first.

[jraju]

Hi, I am also waiting for boggins suggestion.
Hi, Samson, I also do not know anything about the gpresults. I just came to know from a site that suggest to know, the AD active directory, again, i do not know, what is active directory.
I asked the dlink customer care , and they simply say, that everything is right in the router and it is only system fault. Sometimes, this kind of problem is annoying and it seems that we have to live with it.

[Boggin]

I think I'd be tempted to reinstall Win 7 - a chew I know, but as it's computer specific, I think you need to start from scratch on this where the adapter driver and network will be installed afresh.

Somewhere along the line when you installed Win 7 and named your computer - that seems to have leeched for want of a better word, into your network set up.

Factory resetting the router doesn't have seemed to resolve because the laptop, as far as I know doesn't have the same details in its ipconfig /all - or am I mistaken in that ?

[jraju]

Hi, Boggins, i did not have any network drivers . But i downloaded the same from realtek.com to get my network connection at the first instance after installation.
Is there a technique for naming the computer. I just give a name and it added pc-name to it, as for as i could remember.
Network slot, does not glow in my system, to know that  it is working or not.
This motherboard has no light, and moreover, there is a click missing when i insert the ethernet jack to the back of the computer.
I can reinstall windows, but what do you suggest in
that seems to have leeched for want of a better word,
What would you suggest for naming, should i include \before the name or just name anything. Should i use caps on the names, should it contain more characters?

[Samson]

J. Did you read my post #54? about naming. https://www.lifewire.com/naming-rules-on-windows-networks-818238

You could try this to check the NIC, realtek diagnostic tool 2.0.3.0, here  http://www.realtek.com/downloads/downloadsView.aspx?Langid=1&PNid=14&PFid=7&Level=5&Conn=4&DownTypeID=3&GetDown=false

[Boggin]

What puzzles me is why it seems to have taken part of your computer name and set that up as a DNS Suffix.

On the odd occasion that I have factory reset my Toshiba Win 7 laptop, I use caps and it adds -TOSH to the computer name, but doesn't add any of that to the network settings as you can see from the ipconfig /all that I've posted.

The three Toshiba laptops that I use are named TOM26-TOSH, BRUV26-TOSH and KAM4-TOSH - perhaps just using one name may be the answer - I don't know, but it would seem to me that to rewrite something, you need to start from scratch.

Why not call the computer JRAJU

From memory, during the process of a factory reset, it installs the network adapter drivers, sets up your network and connects you to the SSID but I've only ever used machines that have included wireless adapters, so don't know how Windows does that when you only have Ethernet.

However, as nothing you have tried will remedy this business Domain that it is trying to connect to, then I can only suggest starting afresh.

[jraju]

Hi, samson, i already tried that tool you posted and there was no error. I do not know about EEE test, that the facility has. It gives normal mark and no error.
Hi, Boggins, Computer name could be changed even after installation. Is it correct, you could change to anything at any time.
Can i remove all the network, home etc..etc and then try to fresh those. Can i remove all the group of network? How to accomplish that? Regarding other things, dlink representative says, as it works perfect in xp sp3, without any problem, there was problem in windows 7 and so the system is somewhat having problem.
I asked about domain.name, He says that it is default company design to take the domain.name and there is no issue in it.
Did you see my gpresults
i did not know, i just executed and found some details. What is active directory. What acccount, i am logged. I am only having one account. ple

[Samson]

What puzzles me is why it seems to have taken part of your computer name and set that up as a DNS Suffix.

When J named the PC, it was "sarochan.chandru", there should not be a "." in the PC name. I am of the opinion that this is the cause of the DNS Suffix issue in his network and subsequent PC name changes have not ammended the network settings to resolve this.

[Boggin]

I think once something has been set then it will stay that way.

I don't know why it is trying to connect to that domain or how it came about and I can't see any other way of trying to resolve it, but if you have any other ideas.....

[Samson]

I am all out of suggestions on this one....Pretty sure all options have been tried and failed.

Bite the bullet J, a fresh install and as Boggin suggests. just name your PC something simple, JRAJU seems as good as anything, as long as your laptop or phone do not have that name
