You need to be more specific!

1. are you trying to simply access a dns server from home to use internet?
2. are you trying to access a dns server that has been configured to be used internally in a corporation for the porposes of resolving ip address into name servers inside your intranetwork??
3. what operating system do you have, xp, 2000, server 2003, vista?
4. what is it in general what you're trying to accomplish (ex. be able to go on internet from your home, from your corporate computer...etc).
5. are you trying to reset a dns server for the porposes of connecting to it? is that a server you're in charge with (is that server part of the network you manage)?? if that's the case. you can restart the DNS server service located in your DNS server 172.29.71.1. make sure also your dns client on the local machine is enable or you won't get get it to work. you can also try restarting the service altogether.
6. also check that your subnetting homework is correct and that you have ip addresses and your subnet mask properly entered on you DNS server and your ip address matches both your DNS server and client using that server to resolve ip address.

if you are just trying to use your home computer to go online using the dns server your ip address has for you to use for the porpose of going online and browse your favorite websites.. more than likely you don't need to enter any dns server configuration as that is dinamically assigned, you will only have to configure your tcp/ip properties for your ip address and dns server configuration to be assigned or configured automatically.

You cam try doing a power cycle. Turn off the modem, router (if you have one) and your computer. after 1 minute turn on modem first then router and computer. If you still can't communicate or ping the DNS it could be a firewall that is blocking it.

I just did a clean install of Windows XP and installed a wieless compact USB adapter and am connected to our wireless network but can't access the internet. Any idea why?


Most likely your DNS is not being recognized or getting through. You can do a diagnosis using IE8 and see what it comes up with. Also you can reset the works and try again to get the DNS to answer the router. If not call your internet provider and manually install the Primary DNS numbers make sure that the Network is set to auto detect. Thanks for using FixYa! John

Tip on speeding up your Internet connection.


I have high speed and my Internet was sluggish at best for months. I tried everything including the following Resetting my cable modem, replacing my cable modem with a newer model. Resetting my Wi-Fi router, replacing my Wi-Fi router. Reinstalling my operating system. Updating my network drivers. Scanning for Malwere and viruses daily. I tried different browers including Firefox, Chrome and others. I updated Internet Explorer with all the latest patches.

I have determine that the DNS server was the issue. The DNS server is a translator, it allows us to just type in the website name like www.microsoft.com instead of remembering numbers like 216.239.51.99. I fix mine by using Open DNS instead of my internet provider DNS Server.

Here is how to fix it. Go to control panel, then click on your local area connection icon. Click on properties and then double click on TCP/IP Internet Protocol. Leave the top settings alone, which will still obtain the IP address automatically. Type in the Open DNS Preferred DNS server settings of 24.25.5.60. Type in the Open DNS Alternate DNS server settings of 24.25.5.61. Reboot your PC and enjoy the speed.

Need help connecting wireless router


To connect a laptop to a wireless network for accessing internet....you have two ways:-

  1. DHCP (Dynamic Host Control Protocol)
  2. Manual entry of settings in wireless adapter properties.
1.DHCP:-
In DHCP method you dont have to enter any settings on the wireless adapter. The wireless network which you are connecting will automatically assign an IP Address to you. But to use DHCP it must be supported by your wireless network.

2. Manual entry of settings in wireless adapter properties.

This method is mostly used over wireless Connection in small networks connecting 2-200 computers. In this method you have to obtain the following information from your connection provider.
  • IP address (Its format is "xxx.xxx.xxx.xxx")
  • Default gateway address (very important)
  • Primary and secondary DNS (If not given then you can use "8.8.8.8" as primary DNS and "8.8.4.4" as Secondary DNS...thats free DNS service from google and its very fast)
  • Subnet Mask (not needed mostly...automatically generated)
To enter these settings you have to rightclick the Wireless Adapter>> and select properties>>Then double click the Internet Protocol version 4(TCP/IPv4) and enter these settings. In many cases when you are using proxy server then you have yo use proxy settings also in your browser..
Hope this will help....Cheers..:)

No ip address


Network Card's driver is not installed. Check and install drivers from Device Manager Window.

IP Address can be assigned automatically(through APIPA/DHCP) or Manually.

Automatic:
There is no DHCP server, it takes the Automatic Private IP address(APIPA) or else get it from DHCP server by using "ipconfig" command
Steps: Start>accessories>command prompt>ipconfig /renew

Manually:
Right click on My Network Places> Properties>Right click on Local Area connection>Properties>General Tab>select Internet Protocol(TCP/IP)> Properties>General> select "Use the following IP address> assign IP, Subnet Mask, Gateway and DNS> Press OK Tab.

Tip

Why can't you connect to the Internet?


First check your TCP/IP address - see my earlier tip on checking you are connected to a network. For most recent systems, (not Linux) open a command prompt window (type "cmd" in the RUN window from the start menu) and type ipconfig /all
you should see your network adapter name and IP address, a subnet mask (don't worry) and a default gateway, also a DNS server IP address. If ANY of these are missing, that's your problem, try repairing or resetting the network adapter. WRITE THEM DOWN. You may have more than one adapter, you need to identify which one is used for the Internet connection.
If they are all there, from the SAME window type "ping" followed by the IP address of your default gateway. If this fails, you have no connection to your internet router, find out why!
If this succeeds, type "ping" again, followed by the IP address of your DNS server. If this fails, type "tracert" and then the IP address of your DNS server. The FIRST address that will be reported is your default gateway; followed by your ISP address; if the only address you see is your default gateway, the link to your ISP  is down, give them  a call. If it succeeds, from the same window type "nslookup"
You will see a chevron prompt, type in the name of the site you want to go to, e.g google.com.
You should then see a reply from your DNS server, and an IP address for your required server. If not, then either your DNS server settings are wrong OR the server does not exist. It will be obvious which it is from the reply you receive. If the DNS settings are wrong, you can change them from the Control Panel, Network, Network adapter, Properties, TCP/IP v4 properties menu; try setting DNS server to 8.8.8.8 or 8.8.4.4 and try again.

Need ip adress and primary dns to install a wireless router


DSL or cable? DSL you will only need your usernam/password combo for PPPOE, cable you should be able to just plug it in and go. set your router for DHCP and it will pull all pertinent info from your ISP's DHCP and DNS servers.

welcome to fixya
Make sure you are hard lined into your router before doing this

might want to try this if you have vista at bottom of the start is a search bar type msdos

it will find a short cut double click it and you should be at dos

once there type in ipconfig hit enter

then type in ipconfig/release hit enter

the type in ipconfig/renew this should rest the dns to your router

Dns error


DNS = Domain Name Server

This is a set of specialized servers on the Internet, needed to
translate user friendly internet address such as:

www.microsoft.com

into their binary IP address equivalents, such as:

www.microsoft.com =
207.46.192.254 = (IP address)
$CF 2E C0 FE = (hexadecimal)
1100 1111 0010 1110 1100 0000 1111 1110 (binary)



In order to communicate with Microsoft, your computer
first sends a request to the closest DNS server to resolve
the domain name into a binary address. Once it gets the
binary address of Microsoft, in then prefixes every packet
with a 32-bit destination address, followed by it own 32-bit
return address.

Other specialized computers on the Internet, called routers,
than manage the actual data transfers on a skip by skip basis.

===========

A DNS error means that your computer is either unable to reach
the pre-determined DNS server, or the server is unable to resolve
the particular address due to a non-existent WEB site or a
spelling mistake.

The actual meaning of the message depends on which layer
of the internet protocol in your computer, (or outside of it)
generated it.

Martin.
