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.

ESXi 5.0
VMware tools are installed

I appreciate the help!

The NIC is recognized as being on a "Domain Network"

Hi,

Is it possible for you to copy paste the exact response when the nslookup fails ?
By the way, what are you requesting in your NSLOOKUP ? Which name ?

Have a good day

Have you install any windows updates recently?
What type of vNic are you using in the VM? Have you tried using VMXNET3 or if already using it tring E1000?
Have you viewed the host and VM's log files for errors/

All, ended up being port exhaustion on the virtual switch.  System had been upgraded since 3.0 days, only 160 ports.  Bumped to 1060 ports and all is well.

Thanks!
