DNS server unknown

I am trying to get wireless connection to my Toshiba Satellite C655-S5132. However, the company router for NetGear is not allowing me to connect to the internet. The CD that came with the router, is irritating. It needs the IP Address, the IP Mask, the Gateway Server and the DNS, however, when I pull up the configuration for these things, it comes up as
DNS server:Unknown
IP Address:192.168.1.1
Also, when I pull up the System Information, everything: the gateway server, DNS, IP Address, the IP Mask, all have unavailable beside them.
If anyone can give me so help on this, I would be appreciative. I have racked my brain for two days on this router and the other one, a linksys.
Also, I can get the linksys to connect to the computer, but not to the internet.

This is one of those topics that is well beyond this forum but let me try. Beyond the router, you also need an ISP (Internet Service Provider) like AT&T, Cox, or the local phone company. The ISP provides a cable modem which then connects to the router. The router then connects either with a wire or wirelessly to the computers that are trying to connect to the Internet. Just having a router won't get your computer to the Internet. You need the ISP to provide the Public IP address, the DNS Server and the gateway to the Internet. DNS stands for Domain Name Services and it is what converts a website like Yahoo.com into an IP address like 123.5.173.9. From your questions and the nature of the problems you're having, I would suspect that you don't have an ISP or that the router is not connected correctly to the cable modem.

Default DNS server unknown its coming while resolving`

Hi
i have windows 2012 domain controllers, able to successfully resolve dns queries.
But the problem is while resolving default server field its coming unknown. i created reverse lookup for dns server(Domain controller) after that host name is coming..
But after one day again hostname disappeared, default server field unknown coming..
If anybody knows this issue..

Hi,
Have you checked if the reverse lookup record is still present in the reverse lookup zone. Domain Controllers use dynamic registration to register A/PTR records for itself. Make sure Enterprise Domain Controllers group has permissions over the records so
these can be updated. This is found in on the security tab at the record/zone propetties. If you manually created the PTR record then it should have no timestamp therefore it will not be scavanged in case you enabled that function.
Hope this helps.
Regards,
Calin

Your computer appears to be correctly configured, but the device or resource (DNS server) is not responding [and I'm at my wit's end!]

I originally posted this question to the community section and was advised to post it here. Please bear with me as this will be a long post. I'm including the scenarios involving this reoccurring issue, the trouble shooting steps I've already
taken and the results of several diagnostic tools and logs.
I have a Sony VAIOS VPCEBB33FM lap top since 2011. I have had this issue on an off for a long time. I'm at my wit's end. Any new insights or suggestions would be greatly appreciated.
Scenario Details
1) Some times it's on and off through out the day, sometimes it won't work all day, and once in a while it will work fine for the entire day.
2) I've had this issue across several wireless services, Clear Network accessed with WiMax, Library Wi-fi, Comcast cable internet using wireless router and Wi-fi, and Comcast Xfinity Wi-Fi, to name a few examples.
3) Other devices in the household or library will work with no problems such as my smart phone or my roommates' laptops or desktop computers.
4) Once in a while, the built-in wireless adapter is not found and I have to reinstall the driver. Also the diagnostic tool has had to reset my adapter on an increasing basis.
5) I had my hard drive replaced in December 2014 and my system restored from the System Restore disks that came with it when I bought the laptop. Even though I've been online on an infrequent basis it worked just fine for a while. Now that
I've been online a bit more I'm having the same issues again.
Below are my attempts at trouble shooting so far but I still have not been able to consistently resolve my DNS issues
1) Restarting my adapter
2) Turning off my laptop and removing the power supply for 5-10 minutes before turning it back on.
3) Using the IP Config in Command Prompt
     ipconfig /flushdns
   ipconfig /registerdns
   ipconfig /release
     ipconfig /renew
4) Using the NetSh reset in Command Prompt and restarting my laptop
     netsh int ip reset c:\resetlog.txt
     netsh winsock reset
     ipconfig /flushdns
     [restart laptop]
5) Configuring the TCP/IP in several settings
    Select Internet Protocol Version 4 (TCP/IPv4), and then click Properties.
    I have used the following settings:
       a) Obtain an DNS server address automatically
       b) OpenDNS
           208 67 222 222
           208 67 220 220
       c) Google DNS
           8 8 8 8
           8 8 4 4
6) Updating the driver for my Intel Centrino(R) Advanced-N 6250 AGN and Intel Centrino(R) WIMAX 6250 from the Intel website previous having my laptop wiped clean in 2014. It still did not resolve the issue. My laptop
manufacturer as not come up with an driver update for my adapter since 2010. I haven't tried to update the adapter driver from Intel's website since having my laptop repaired due to the fact that Intel strongly recommending using the manufacturer's updates
instead and frankly it didn't make much of a difference when I did it the first time.
7) The last one I've tried as of today is going into Services and changing the start up type to automatic for the following:
       Computer Browser [changed from manual to automatic]
       DHCP Client [already set to automatic]
       DNS Client [already set to automatic]
       Network Connections [already set to automatic]
       Network Location Awareness [changed from manual to automatic]
       Remote Procedure Call (RPC) [already set to automatic]
       Server [already set to automatic]
       TCP/IP Netbios helper [already set to automatic]
       Workstation [already set to automatic]
...and I'm still having DNS issues.
My only guessing are that my laptop came with a lemon adapter that needs to be replaced, some advanced setting(s) that I'm not aware off, or my firewall/anti-virus is interfering. I've used Symmantic Anti-virus and Firewall in the past and currently
Avast Anti-Virus with Microsoft Network Firewall. I've had DNS issues with both anti-virus/firewall set ups.
Below are the results from the diagnostics and tests that I've ran.

More about the environment:
        - Very small domain - two AD servers (both Windows Server 2012), two computers (running Windows 8) and three or four devices (printer, phone, WiFi access point, etc.).
        - The network (DHCP, DNS, servers and gateway static addresses etc.) is both IPv4 and IPv6.
        - There are DNS running on both DC servers.
        - The servers have static IPv4 and 6 addresses.
        - The servers have both DNS addresses (both IPv4 and 6) in their IP configuration.
        - Single forward lookup zone - mydomain.com (and of course _msdcs...).
        - Two reverse lookup zones one for IPv4 and one for IPv6.
        - DHCP has the two DNS servers in the options.
Call me old-fashioned but I've been using "nslookup yahoo.com" to diagnose my network problems for years and now when it doesn't answer unless i specify the dns server, makes me nervous. Am I right and if I am can you suggest possible problems in
my configrations.
Thanks Val

It's only showing "unknown" for the IPv6 address.
Go into your IPv6 properties, and set the IP and DNS address settings to be obtained automatically.
Then in Manage network adapters windows, change the view options to show Menu, then click on Advanced, Advanced, and make sure IPv4 is on top instead of IPv6.

Dns server in solaris 10 issues

Hello,
I have configured /etc/resolv.conf with the following:
nameserver 8.8.8.8
"nslookup www.yahoo.com" works fine to get the IP, but "ping www.yahoo.com" failed with with unknown host.
Did I miss something to configure my dns server?
Thanks for the help in advance.
Tom

You haven't configured a DNS server. You've told nslookup which DNS server to use to resolve a name to an address.
Try:
http://www.convery.me.uk/blog/?p=16
for assistance with your issue.
Don't forget that Solaris 10 uses both hosts and ipndoes. Later versions have these files linked together.

Resolving arabic domain name in Solaris DNS server

Hi..
I just quickly want to know how can i define arabic font domain name to get resolve in my DNS server?
I tried to put entry with arabic name but editor making it abnormal, i recently get arabic locale installed on server through north Africa region. Locale is now showing me "AR" ..
Thank you

Sorry my bad.... slight mistake in my question...Here is my corercted query--
After successfully connecting to the internet, when I do NSLOOKUP on the DC, the DNS doesnt resolve my internal domain/site but instead resolves external sites on the internet.
My computer FQDN is nri.wwe.com
Domain dns name is wwe.com
The above should get resolve internally but it searches on the internet.
This is how it should work
& it works perfect when I disable the other NAT network adapter (i.e. disable internet connectivity on my virtual DC)
C:\>nslookup nri.wwe.com
Server: nri.wwe.com
Address: 192.168.1.11
Name:    nri.wwe.com
Address: 192.168.1.11
But when I again enable internet connectivity, this it what happens.
C:\nslookup www.wwe.com
DNS request timed out.
    timeout was 2 seconds.
Server: UnKnown
Address: 192.168.12.2
DNS request timed out.
    timeout was 2 seconds.
Non-authoritative answer:
DNS request timed out.
    timeout was 2 seconds.
Name:    www.wwe.com.nsatc.net
Address: 64.152.0.124
Aliases: www.wwe.com
And when I again nslookup, this is what I get,
C:\>nslookup www.wwe.com
DNS request timed out.
    timeout was 2 seconds.
Server: UnKnown
Address: 192.168.12.2
DNS request timed out.
    timeout was 2 seconds.
DNS request timed out.
    timeout was 2 seconds.
DNS request timed out.
    timeout was 2 seconds.
*** Request to UnKnown timed-out
Now this 192.168.12.2 is VM assigned DNS via VM Natting with its own DHCP. If we do it manually, none of the virtual machines can connect to the internet. So I cannot fiddle with it anymore as I have already that as well.

DNS debug logging to determine if 2008R2 DNS server is still being queried?

We are removing multiple DNS servers. We have removed those servers from DNS reference from all dhcp scopes, and ran script across all windows servers to make sure they are not being used. There still might be Linux/telecom/workstations manually
set that we do not know about, so I was going to use debug logging just to look for queries that are coming and to try and determine where they came from. I have debug logging set to log packets for Incoming, UDP, Queries/Transfers, and Request, but having
trouble figuring out this log. Here is an example of what I am seeing. Does anyone have a reference for this? I am having trouble finding one.
Is this saying that a computernamed POS188 made a query for a host(A) record? or is it saying that a query came in from 128.1.60.221 for a host(A) record named POS188? Just looking for reference to help explain this. The good news is the only
IP address that shows(128.1.60.221) is the IP of the DNS server, but the only thing I could find for reference was this -
http://technet.microsoft.com/en-us/library/cc776361(WS.10).aspx
9/16/2014 12:05:23 AM 1144 PACKET 000000000624CBD0 UDP Rcv 128.1.60.221    8952   Q [0001   D   NOERROR] A
(8)POS188(11)contoso(3)com(0)
Thanks,
Dan Heim

Hi Dan,
The example you provide means that the DNS server receive a packet sent by 128.1.60.221,and the packet is used to query a host(A) record named POS188.contoso.com.
And the detail information about each field of the message is shows below. It is also showed in the dns.log.
Message logging key (for packets - other items use a subset of these fields):
                Field # Information         Values

GSS as primary DNS Server for Intranet

Hi,
Can the GSS be used as a as primary DNS server for Intranet? An additional DNS server can be configured to answer the unknown Records like MX by GSS.
if it can be configured, I would be thankful if anyone shares with me the brief configuration steps Apart from configuring Answers, answer groups, domain lists, source address lists, DNS rules.
with thanks

Yeah I'd certainly recommend against it! So essentially the client machines are unable to update or query dynamic AD related DNS records since they're not pointing to the DNS servers actually used by your AD server(s). I could well imagine that causing
issues, and meaning that some AD functionality won't work correctly.
I know you can directly integrate BIND with AD, eg so that the BIND servers are the ones used by AD, though I haven't tried it, but this seems to be neither.
I can't find any articles relating to your exact situation, presumably no one else has tried to use such a mixed and disjoined setup. I'd focus on looking for articles relating to why you shouldn't point your users at a router (most commonly in small setups
on ADSL) for the DNS rather than directing them to the server for DNS and then having that query the router for external results. It's a more common scenario and you're more likely to find articles relating to it.
One article you might find useful is
http://msmvps.com/blogs/acefekay/archive/2009/08/17/ad-and-its-reliance-on-dns.aspx which talks in terms of using your ISP's DNS servers on the client machines, but in your situation it sounds like the BIND servers are essentially providing an equivalent
setup.
There's also various discussions and comments on the topic elsewhere on these forums, for instance
http://social.technet.microsoft.com/Forums/windowsserver/en-US/c3ba3859-765e-4b3f-add0-eaf2c18e1068/i-have-dns-in-a-router-and-i-want-to-install-domain-controller?forum=winservergen and

Dns server secondry

Hi ,
I am facing below error on nklookup , ihad entered entries of secondry server in DNS as well as resolve.conf is configured coreectly .
Kindly let me know if o have to do anytjhing else .
This server is secondry dns server .
*** Can't find server name for address 198.152.137.5: Server failed
*** Default servers are not available
Default Server: UnKnown
Address: 198.152.137.5
Thanks

From the output it looks like the nslookup command doesnt know where to find the info from rather than nslookup not knowing where that particular ip is
Have you set up the master server correctly
check the set up of primary secindary and clients
/etc/named.conf
this file should have pointers to other config files, its DNS root servers and the domains it serves and the type of server it is for its domains.
It is also read by in.named at start up and this should be running and restarted if the config has changed.
create the /var/named/named.root file to help non root servers find a root server
create the /var/named/one.zone and /var/named/one.rzone files for mapping the ips to names and for revrese lookups.
create /var/named.loopback
ensure that onl all clients and servers dns is in the /etc/nsswitch.conf file to allow the kernel to use DNS.
set up /etc/resolv.conf
for more detailed info look at the network admin documentation for the version of Solaris you have.

NIS+, DNS server, DHCP

I have installed Solaris 2.8 with all the patches on a PC. I installed NIS+ populating the tables from the files included into the folder /nis+files. Now I want to install DNS server for a small local network made up by two hosts: a Window2000PC and a Solaris 2.8 PC. I want to use DNS server of Solaris 2.8 to test the functionality of a DNS client of the PC. And after I want to install DHCP to test the same funcionality . I should like to make things step by step, first with DNS server and after with DNS server together to DHCP server too, both installed on Solaris 2.8, coexisting .
On the network i have another host ,a router, that gives me the acces to Internet
How do i install DNS server on Solaris 2.8, and DHCP server ? Can someone help me ?
Thank you in advance
Marcello

Hi Guys,
I want to thank all for the valuable information.
I thought of sharing my own comments.
I have two SunSparc Ultra10 machines. I want to network them together using a Linksys router (Cisco) so they could communicate and also to be able to access the Internet. I let the router to do the (DHCP) work, however; since the routher doesn't send hostname I always got 'unknown' and I need to have proper hostname to do my training work. So, I've read this page and I thought I could contribute the result of my work.
(assuming my hostname= sys41)
On Solaris 10, all what I did,
1. On /etc/hostname.hme0 .. I've added,
inet sys41
2. I've created /etc/nodename .. and added,
sys41
3. On /etc/default/dhcpagent .. added,
REQUEST_HOSTNAME=yes
actualy, it was there, I just removed the comment (#) and changed it from no to yes
and double checked that I have ,
PARAM_LIST=1,3,6,12,15,28,43
That's all, I didn't need to change anything else nor add any script file or anything.
The following files where not there on my Solaris10 machine,
/etc/init.d/network
/etc/init.d/inetsvc
On Solaris 9,
1. On /etc/hostname.hme0 .. I've added,
inet sys41
2. I've created /etc/nodename .. and added,
sys41
3. On /etc/default/dhcpagent .. added,
REQUEST_HOSTNAME=yes
actualy, it was there, I just removed the comment (#) and changed it from no to yes
and double checked that I have ,
PARAM_LIST=1,3,6,12,15,28,43
I had to add 15,6,28 on my Solaris 9
4. /etc/init.d/network
changed all 'unknown' to 'sys41' which is my hostname
5. couldn't find /etc/init.d/inetsvc !
Then I've deleted /etc/nodename on Solaris 9.0 and still worked fine ..
On Solaris 10, I've deleted /etc/nodename and it didn't work.
So, I guess for Solaris 10 /etc/nodename is very important .. For the Solaris 9, /etc/inet.d/network did the job !!
Hope my comments were helpful... Regards ..

Moving from Exchange 2007 to 2013 (leaving the DNS Server for it's own dedicated server)

Hello! I am quite new to Exchange and Server management in general. I will do my best to explain my situation.
I am looking to move my Exchange server off of our DNS server. When we installed them on the same server, we did not have the funds to buy 2 separate servers. I am told that it is best to separate the two. I have followed the Microsoft instructions for installing
the prerequisites for Exchange 2013 on a 2012 R2 server, and i am at the point where it wants me to configure AD LDS. As I have active directory running on the current server, I was a little hesitant to just install it without understanding what i am doing.
After the AD LDS is configured, I believe i can move forward with installing Exchange 2013 (all 3 roles will be hosted on the new server), export the mailboxes from 2007 server and import them into the new Exchange 2013 server. After 2013 is up and stable,
I plan on removing 2007 from the old server (DNS server).
What are my next steps after importing the mailboxes? Am i missing important details that I need to change or migrate?
My biggest fear is that nothing works after the installation and moving the mailboxes over. For that case, it makes sense to keep 2007 installed as a fallback for when my installation fails and all i have lost is just my time :)
Current Server:
Windows Server 2008 Standard (64 bit)
1. Roles: Active Directory, DNS, IIS
2. Software: Exchange 2007
New Server:
Windows 2012 R2 Server
1. Roles: ???
1. Software to install: Exchange 2013
Thank you for any help you can provide!

These are good resources, but i am still caught up with the active directory issue. Am I able to keep the old Domain/DNS/Active directory on it's current server and move Exchange 2007 off onto a new server (with Exchange 2013)?
In the first example, he is moving everything (domain controller, exchange, users, etc) onto a different server and decommissioning it.I've been told that it would be better practice to keep the domain and exchange on 2 different servers. Is this true?
I go to run commands like:
.\setup /PrepareAD /OrganizationName: orgname /IAcceptExchangeServerLicenseTerms
on the new exchange server, as a prerequisite and it doesnt recognize the command - even after following the steps before. Is this because the new server is not a domain controller? does it have to be? What are the best practices for setting up a server(s)
with exchange + domain controller?
Thanks for responding.

DNS Server problems with ASA 5505

Hi guys,
we setup a new ASA 5505 which is mainly used as our VPN gateway. The ASA is configured and controlled by our ISP (and this is where the problem starts )) and they somehow cannot manage to get the VPN settings really working.
So, here is our problem.
our machines(Windows 7) are configured to get the network settings through DHCP (Windows 2012 Server).
Before I connect with AnyConnect to our VPN gateway, the DNS Server setting in the network settings for the adapters(IPv4) are set to 'dynamic'
When I now connect, this setting is changes to a statc entry (which is our DNS server).
When disconnecting, it is not reverted back, which means I have to do this always manually.
What I do not understand is the fact, that the DNS server is set for all the adapters, shouldtn't it be only set to the anyconnect adapter?.
The interesting thing is, that when I connect to a different ASA, this does not happen. The ISP is now saying, that the machines are configured exactly the same and that they cannot reproduce, but I can't believe this.
This issue shows up at every machine which connects to our vpn, so it is not only a single machine which might be misconfigured.
Do you have any idea what might cause this issue?
btw, the second ASA (which works) is from our partner company, so we cannot simply copy the config
THanks in advance
Patrick

Nice to see someone from BT has addressed your issue
I have this exact same problem, seems completely bizarre, I'm pretty sure I had the same problem with the original home hub (i have the latest one now). Can you confirm whether the problem does affect anyone with a bt home hub and not just the one that the dyndns is pointing at? I'll try and confirm by hitting your domain from my home connection.

How many DNS record need to create in Internal & external DNS server for exchange?

Hi friends,
I recently installed Exchange Server 2010 in my organization for testing purpose and I've register a pubic ip too for exchange server on godaddy.com. How many
internal & External DNS records reqired to configure on external & Internal dns server so my all feature like Auto-discover, Activ -sync,& webmail start working perfectly.
It's my first time configuring exchange for a organization.
Thanks & Regards,
Pradeep Chaugule

Hi,
Just as what ManU Philip said, you need to create
Autodiscovery.domaincom and mail.domain.com for external dns server.
Generally, you configure your Exchange Servers as DNS clients of your internal DNS server.

Hello I'm having a no dns server problem on my time capsule

Hello I'm having this same problem:

Hi everyone,
I just bought a new AirPort Express and Comcast is my ISP. I ditched my old Belkin wireless router, connected the Comcast modem directly to my AirPort Express, and it appears to be working great. I can access the internet wirelessly and also play music using AirPlay through my stereo speakers.
However, when I open the AirPort Utility, the utility tells me that I have two problems with my AirPort Express:
Apparently I have no internet connection (the utility tells me that "Your AirPort base station does not have a valid IP address."), even though I can access the internet just fine.
I don't appear to have any DNS server addresses (the utility tells me that "This AirPort base station doesn't have any DNS server addresses and might have trouble connecting to the internet.")
Does anyone know if these are serious problems that I need to address, or can they be ignored? I don't want to start tinkering with the AirPort Express's settings until I am better informed, because right now everything is working as far as my access to the internet is concerned.
and I tried to :

Anytime you change networking hardware, it is always a good idea to perform a complete power recycle of your networking components.
I would recommend that you do the following as a minimum:
Power-down the modem, AirPort base station, and computer(s).
Disconnect the AirPort base station from the Internet broadband modem.
While all of the devices are powered-down, perform a "factory default" reset on the base station. This will get it back to its "out-of-the-box" configuration and make setting it up much easier, especially if you use the "Assist me" process within the AirPort Utility. (ref: Resetting an AirPort Base Station or Time Capsule)
After the base station resets, go ahead and power it back down.
Reconnect the AirPort base station to the Internet broadband modem. For the Extreme and Time Capsule, be sure to connect the cable to the base station's WAN (circle-of-dots) port.
Power-up the modem; wait at least 10-15 minutes to allow it adequate time to initialize.
Power-up the AirPort base station; wait at least 5-10 minutes. Note: The AirPort's status light may continue to flash amber after it has intialized. That is because, there may be some additional configuration items necessary, like setting up wireless security, before the overall setup is completed to get a green status.
Power-up your computer(s).
In this basic configuration, the AirPort base station will broadcast an unsecured wireless network with a Network Name (SSID) of Apple Network NNNNNN. Network clients, connected to the base station either by wire or wireless, should now be able to access the Internet through the ISP's modem. Once Internet connectivity has been verified, you can use the AirPort Utility to configure the base station for wireless security and any other desired options. Please post back your results.
BUT NOTHING IT STILL SHOWS NO INTERNET CONNECTON on my capsule and NO DNS SERVER ...
I have tried to HARD RESET it resets ( with a Network Name (SSID) of Apple Network NNNNNN) and it connects to internet, it also says setuo complete in airport utility but once I go back into Airport utily cause Time capsule is still flashing amber it says NO INTERNET CONNECTION and NO DNS SERVER ...
anyone has any suggestions PLEASE and Thank you

Check the Ethernet connection to the AirPort Express. Make sure that the Ethernet connection from the Comcast modem is connected to the WAN port on the back of the AirPort Express. The WAN port is the one with the circle of dots shown over the port.
It sounds like you are connected to the Ethernet LAN port.

Time Capsule blinks yellow,when I go to airport utility to set up, it Says This apple wi-fi bse station doesn't have any DNS server addresses and might have trouble connecting to internet. My internet works, but I can't back up anything. What do I do??

Worked fine for about a couple of weeks after my son -law installed the time capsule. I can access the Internet both from my wife's I phone and from my desktop. I think that I need to get the DNS server numbers and put them in the two blanks; but where do I get them? Thanks, Jim

If the modem is also a router, either use the modem in bridge and run pppoe client on the TC.. that is assuming ADSL or similar eg vdsl. If it is cable service.. and the modem is a router, then bridge the TC.. go to internet page and select connect by ethernet and below that set connection sharing to bridge.
Please tell us more about the modem if the above gives you issues.
