Certification Authority 0x8009480f error

Certification Authority 0x8009480f error : the dns name is unavailable and
cannot b e added to the subjectalternatename.
This error I get all the time when automatic certificate allocation wants to
give a certificate to a domain pc.
I have a W2K3 domain, the pc is W2K SP4.
in the logs there is nothing wrong with DNS.
Tried to kick te pc out of the domain and back, nothing changed.
Removed CA and reinstalled, nothing changed.
Something strange when I follow procedure for configuring aut. cert. alloc.,
after selecting the computer out of the templates, I won't get the enterprise
ROOT CA, just window with name and computer.
Is this the cause of the above problem? What can I do to solve this problem.

Thank you.
