Bob,
I bought a laptop so I could take it with me and hopefully connect to free WIFI.
I noticed that OpenDNS (I had OpenDNS setup in my laptop) wasn’t working wherever I got connected.
Sometime ago, somebody posted here in our forums a long list of DNS servers that weren’t up to date and unsecure.
Use of the Norton DNS client will force any WIFI to use Norton DNS, merely configuring Norton DNS in your computer or router isn’t enough.
Norton DNS is kept up to date and secure, I want to be sure of my connection. http://client.nortondns.com/nortondns-win-current.exe
