Windows 7: the dns server isn't responding

Win 7 Pro 64 bit
the dns server isn't responding

I've got 20 desktop PC's on a network. All of them are connected via hardwired LAN. One of them cannot connect to the internet at all. The Chrome browser and Win 7 diagnostics say, "the dns server isn't responding". All other PC's are working fine.

Did an ipconfig /all. PC is assigned an IP address... 192.168.xx.123 (preferred) DNS is 192.168.xx.240. I can ping the DNS server from the PC that cannot see the DNS server and get a clean response. From my PC I can ping the offending PC, and from the offending PC, I can ping my PC.

I've reset router and cable modem. On the offending PC, I've done a dnsflush,, reset winsock and ipv4 stack, all to no avail.

I can't see any difference and yet this one PC cannot access Exchange, nor browse. ipconfig /all results attached.
