SCCM 2012 - Error "2097154172" and 0x800706ba

It could happen that, trying to install the SCCM Client to new Workstation/laptop it goes wrong.

On the server, opening ccm.log you could find this errors:

---> Unable to connect to WMI on remote machine "WORKSTATION_NAME", error = 0x800706ba.

---> ERROR: Unable to access target machine for request: "2097154172", machine name: "WORKSTATION_NAME",  access denied or invalid network path.

Probably it's a DNS problem, infact:

1. Ping workstation
2. Ping -a IP Workstation
3. It could not resolve the Workstation name, so we have found which is the problem (DNS query)
