Cannot communicate w/ Primary DNS server

I have a small home network. This morning when I went to turn everything on, I was unable to connect to the internet on both pcs. Now after troubleshooting, my network is connected and it shows internet on both pcs; however, the pc used as the main server cannot connect to internet. Diagnostics produces warning that it "Cannot Communicate with Primary DNS SERVER." Diagnostics pinged but no response back. Any suggestions or advice? Thanks!

 

m$ just released a patch for DNS maybe that is it, try removing that. The patch cause ZA to stop Inet traffic also... who knows.
