OpenDNS not working one computer

[elurban3d1]

Recently wiped the settings on my Verizon Fios Actiontec router and opendns is not working on one of the computers.  I've wiped the DNS cache.  Any thoughts?

Many, but not enough information to know what is relelvant. How did you determine that OpenDNS is working on al of your computers but not on this particular computer? How have you configured OpenDNS to work on your router and the devices on your network? Does this occur with just one browser, or on all browsers installed on the computer? Is there any software, especially antivirus software or browser plugins that could be intercepting DNS calls and rerouting them somewhere. For instance one version of Avast AV reroutes all DNS traffic to their own servers if a particular option is turned on.

Actually figures it out last night....the computer that would not connect was using a different dns address.  IIRC once I set the IPV4 setting to match the opendns addresses it worked fine.

If you had the OpenDNS resolver addresses on the router, then resetting the router to the default factory settings will indeed purge this configuration, and you will no longer be using OpenDNS at all.  You have to do it again then, of course.

"the computer that would not connect was using a different dns address.  IIRC once I set the IPV4 setting to match the opendns addresses it worked fine."

This is somehow not proper.  If you configured the OpenDNS resolver addresses on the computer, what role plays your router?  If you have the OpenDNS resolver addresses configured on the router, then there is no need to configure them on the computer as well.  You must just set the computer to obtain the network (inc DNS) settings automatically via DHCP from the router.

I did this:

Scenario 3: Working except one computer

In this scenario, you have configured OpenDNS on your router, and it works for most of the computers, tablets, and WiFi-Connected iOS and Android devices on your network, but it doesn't work on one computer. To confirm if your device(s) are configured for OpenDNS, please visit http://welcome.opendns.com and look for the check  mark. 

Potential Cause 1: Your computer is directly configured for another DNS Server, and therefore is bypassing the OpenDNS settings on your router. 

Resolution 1: Check the configuration on your computer to ensure that different DNS server settings are not configured. On Windows, check your configuration using the Windows configuration instructions, but rather than enter the OpenDNS numbers, ensure that they are set to "Obtain DNS server address automatically".

Correct, this is the solution I lined out above.
