Inventory service installation failed

Hi all,

I made a new ESXI 5.1 server and I create a VM with windows 2012 for installing vCenter but i have some problems.

when I try to install Inventory Services I have message : "The Fully Qualified Domain Name cannot be resolved with nslookup..."

But when I execute NSlookup it works fine.

Any idea to resolve this?

Is Vcenter compatible with windows 2012?

Thanks by advance.
