Using NW6.5

I removed NDS from the server listed as the host server in the Org_CA.
Then removed the server from the tree. Attempts to subsequently put a new
server into the tree failed with "cannot create PKI objects" type of errors.
I recreated the OrgCA, but had to point to a different server that has
Certificate Server installed. I then ran PKIDIAG on all my servers to
replace invalid certificates. With this new CA I can create new
certificates, but still cannot successfully install a new server into the
tree without getting the PKI error (-634).

Did I miss something?
How can I fix my Security Container objects so that they all play together?
How can I get a new server into the tree now?
Thank you for any insight.
