on my Win7 desktop machine, DNS lookups started failing, I can ping 4.2.2.2 .

Ii can access my web servers by IP , but even nslookup replies 'No response from server" , tried server 4.2.2.2, server 8.8.4.4,

I have tried multiple Name server settings, all other devices on my home network are doing fine, its like DNS is blocked, I have shutdown firewalls, flushed dns, registered dns, even onlined a different Ethernet card,
Eset NOD32 runs clean, Commodo FW is clean, all VPN software is removed,

Any Ideas ? I am 20 yr comp geek so don't hesitate to suggest something complex this is strange, only on one workstation too. I think i have a glitch in the registry for the IP stack or some kind of dns client hijack is getting past my NOD32 and Windows security... ;-(

Thanks in Advance

Have you made an image of each system for backup? As a 20 year tech, the answer should be yes. Reinstate that image to the problem PC.
