Dear people, I am having a great trouble with my laptop as my connection cuts occasionally but on the modem I am connected to the internet. When I troubleshooted the issues it says DNS SERVER ISN'T RESPONDING, if anyone knows where is the problem ans how can I resolve it, please post your comments, Thanks :D

Next time it happens, with regard to troubleshooting possible DNS issues...you should use NSLOOKUP instead. Many of the applications and/or troubleshooting wizards may indicate an DNS issue if the app cannot resolve for DNS. It could be a networking issue preventing getting to DNS.

Hello, try using 4.2.2.2 as primary DNS server in IPv4 settings and check if the problem is persists or not. If yes, then I suspect that there is a problem with your ISP DNS server (I supposed here that it is the used one, by default, for DNS resolution). If the problem persists then I suspect that there is a connectivity problem and I suggest contacting your ISP Technical Support. Use nslookup like JM mentioned to check that all is okay with DNS resolution. This posting is provided "AS IS" with no warranties or guarantees , and confers no rights.
