| It took about an hour for me to resolve successfully. You could say that it is a network problem. I dont think thats the case unless you have noticed problems with the router and modem. This issue is most likely going to be at the application layer. The network layer is working fine if you are able to ping and get a reply. The guilty application in this case is most likely Norton. run / services.msc
look for symantec core, and other related components. If you had 360 you will want to enable and start automatically . This could be the quickest fix.. Check for conflicting apps such as symantec, mcaffee, avg, and make sure they are installed correctly and running. You may have to restart these services. Run lspfix or winsockipfix.exe to see if your network stack is corrupt. Remove any security patches that may have conflicts with your system. Run ipconfig /flushdns if you have to or use the netsh utility. Conflicting apps is most likely the cause make sure you have backups and save restore points. These hiccups will occur so take preventive measures and establish contingency plans. Bottom line Norton was the problem you may have reinstall the app to fix the problem. Even when the application has been uninstalled it could still create interference.
