I have one virtual 2008R2 server. It was doing just fine. Today DNS resolution began to fail. All the other virtual servers, same vSwitch, vLAN, DNS servers, subnet, ESXi host, are fine. I pull the vNIC, wipe hidden devices, reboot, add a new vNIC, don't connect it yet. Configure the appropriate static. Then connect it to the vSwicthc. NSlookup works fine. Great? No. Give it five minues and NSlookup begins to fail again. Wash, rinse, repeat.
VMware tools are installed
I appreciate the help!
