I have a laptop (windows 10) that suddenly stopped accessing a number of different random websites, including this one... saying "server DNS address could not be found". Other websites, such as Facebook and yahoo, it still accesses. It does this on the chrome browser and the IE browser. The tablet I'm typing on right now works fine however, and accesses everything without problem. This morning both were working properly; this is a sudden development.

By the sounds of it your internet service providers main DNS servers are having issues or, network issues. It could be due to your ISP doing network maintenance on their part as well. What can you do? Well instead of using the ISP's DNS you can use a public Google DNS. Inside your router change the DNS to 8.8.8.8 & 8.8.4.4 However, I don't recommend that you permanently change them from your ISP.

First try technonymous' very good stuff! If it appears to not yet work, if you're using a 3rd party firewall, then it's possible that it is set a little too assertively.  What firewall are you using?  This happened to me -- not the DNS error per se -- for awhile a great number of web sites would not appear.  Again, do what technonymous advises first.

I should add some further detail I guess... The tablet is part of my Verizon wireless service, connected to the internet the same as my smartphone, a 4g wireless connection. I have no router; the laptop is connected via the tablet when the tablet's mobile hotspot is toggled to "on". Something happened since this morning to cause this. The tablet continues working fine everywhere, such as here, yet two feet away my laptop cannot reach bleepingcomputer.com. How do I loosen its firewall security settings in order to try that?

What firewall is the laptop using?  If it is using Windows' built in firewall, then -- there is no settings to adjust, it's not the problem.

Control panel only shows windows firewall, so I'm assuming that's it. There are options to turn it on or off, current state shows on, with connection to "active public networks" via the tablet.

Since Windows Firewall is very likely not the problem, go ahead and do technonymous' good stuff!

I'm not sure how to do that -- I don't know how to change dns settings. I may call Verizon tech support for advice

Well, looks like i've got success with Verizon tech support -- they "refreshed" my profile on the tablet service and now the laptop is working.  Basically a reboot, but on their end.  Hopefully it won't need to happen too often, but the rep said these issues sometimes arise in "VCAs" -- variable Coverage Areas -- which i definitely am in.
