Block incoming DNS (port 53) in your firewall.
|
|
|
|
thks BUT I downloaded fix tool and it said " the dns settings of your computer have not be manipulated by the dns changer" the test is still saying i am running an open resolver and my isp shutdown my internet because of it still don't know what to do...
|
|
|
|
do you have a firewall?
|
|
|
|

The problem is likely not on your computer. The DNS checker uses your IP address to perform a lookup of "thinkbroadband.com". If there is a successful response containing the IP address, it means there is a DNS server running somewhere, allowing requests on the WAN interface on the router, and so anyone can connect. It is normal for a DNS forwarding server to be running on the router, but it should only be available to devices on the LAN interfaces, eg ethernet ports or wifi.
What is the model of the modem/router you are using? You either need to perform a software upgrade if one is available to fix this issue, or add firewall rules on the router to close incoming requests on port 53 to the outside world. If neither of these is possible, I advise you call your ISP and inform them of the problem, assuming your modem/router is provided by them.
However, if you are using a standard home connection, it is unlikely that you will receive probes or requests on port 53. There is only real cause for concern if the DNS server running has a significant vulnerability or is part of a malware package running somewhere on the network. This is unlikely because the malware would need to log in to the router and open port 53.

Hindsight is a wonderful thing! Should have checked before last weekend when the FBI shut down the malicious servers!
Unfortunately the FBI checker has now been closed!
This would have been the best checker to use!

not modem it's on the computer hooked up other computer on modem and did test and it was fine ????

The computer must be running a dns server on port 53.
How did you block incoming port 53 on the firewall?
|
|
|
|
went to firewall settings then blocked it like you said....
|
|
|
|
What version of Windows is it? Check computer management > services and see if there is a service called DNS server running, or a name to that effect. If not then its possibly malware, perform a check with Spybot-S&D, and also whatever virus scanner you use, if you have one.

|
checked services and see dns client in list....??
|

Try disabling DNS client and see what happens. It doesn't affect lookups for me on any browser. Enable it again if disabling causes any problem.

|
|
is the OP confusing www.opendns.com with something else?
|
|
|
|
didnt work

This utility will show you what process is listening on port 53.
Just download it and run it http://technet.microsoft.com/en-us/sysinternals/bb89...

Not if TBB's DNS Checker reports he has an open DNS resolver running.

port 53 doesn't say listening after it like others
|
|
|
|
??
|
|
|
|
What does the entire line say for port 53?
|
|
|
went to firewall settings then blocked it like you said.... You have to block UDP for DNS.
|
|
|
Restart all your computers then do the test again

|
Restart the PC in safe mode with networking and see if the issue is still there.
