CA de CD a Servidor Miembro

[Futurist]

I just demote a DC with CA installed. (W2K3 environment)

I followed the steps to Backup and Restore the CA Server on a member server
with the same Active Directory working. The problem is that when I just send
an email I just can't open it when it's encrypted. I'm getting Event ID: 75
and 74 on Event Viewer. I already changed the permissions on Active
Directory "Services Node" deleting the SID from the old Server to the new
server, Which is the exactly account I must add, the computer object on AD?

Hope to hear from you soon.

Thanks...
