HELP!!! I think I do not have a DNS resolution!?

Question

My company has about 20 computers. But the Internet is really slow! I do not know what to do. I've talked to our internet provider "Paetec" and they say "you have no DNS resolution" I have no clue what that means...but I need this fixed ASAP! Please help me!

Answer 1

If you had no dns resolution you wouldn't be able to ping yahoo.com or google.com etc. What type of results do you get if you pull up a command prompt and try to ping www.google.com what do the ping statistics show? It should say ping statistics for and then sent/received/lost let us know what they say. Also if you could post what you have when you do ipconfig/all that would help a little as well. Basically when they say you have no dns resolution is that you can't resolve a hostname/domain etc to an ip address i.e. www.google.com = x.x.x.x have you tried rebooting your cable/dsl internet connection what about the router?

Answer 2

Calm down... We'll get through this. =)



1) Go to Start > Run. Type CMD and hit enter.



2) Type ping google.com

If you get responses you have a working DNS entry.

If you get 100% failure, you either have no DNS or no Internet access.



3) Type ping 4.2.2.2

If you get responses here, you definitely have an internet connection.

So... If ping 4.2.2.2 works and ping google.com does not, then they are right.



Minimize this window.



If they are right, do this...

1) Start > Control Panel > Network and Internet Connections > Local Area Connection.



2) Right-Click on Local Area Connection and choose Properties.



3) Click on Internet Protocol and click on Properties.



4) Click on the button that says Use the following DNS Server Addresses.



5) Enter 4.2.2.2 into the first one and 4.2.2.1 into the second one. Click OK in that window and the other window.



6) Reopen the text window.



7) Type ping google.com

If you get responses you have a working DNS entry.



This should work for you.



If you have any questions EMAIL ME through this my profile on portal. It goes to my business email address.

Slow isn't no connection - no DNS resolution results in no connection unless you connect to an IP address. (http://209.73.187.220/ works, http://www.answers.yahoo.com/ doesn't.)



Go to http://www.speedtest.net/ to test your connection speed. Use a computer connected directly to your modem. (You'll have to take your LAN off the internet for 2 minutes to do this.)



If the speed is much lower (it may be a little lower) than what it should be, call your provider - they're not providing you with the speed you're paying for.



If the speed is where it should be, something on your lan is slowing your connection.



(Don't measure speed by how long it takes for web pages to open, or by your download speed - unless the connection is to your provider. The internet may be slower - even A LOT slower - than your connection speed. If you want to use the internet you accept the speed the internet is rnning at for the particular connection. [It varies with the path, the server you're connecting to, time of day, day of week, time of year and many other things - over which no one has any control].)
