how we connect the console station to the pks server if the network is configured as domain?

the server is always unavailable when we try connect the console station to the system after logging with a domain account.

 

The DC (Domain Controller) should be 'hardened' using the Domain Controller High Security Policy

The Console Station has to have the LinkDomainGroups VB Script run on it to link it's local accounts with the DC groups created in the previous step.

None of this mitigates the need to have all nodes added to the HOSTS file, which may be your original issue.
