Just upgraded to OES2SP2 on a dsfw server and everything works except adding PC's to the domain which is hit and miss and:

running rpcclient -k localhost -c dsroledominfo gets:
cli_session_setup_blob: recieve failed (NT_STATUS_LOGON_FAILURE)
failed session setup with NT_STATUS_LOGON_FAILURE
Cannot connect to server. Error was NT_STATUS_LOGON_FAILURE

kinit administrator@domainname.org does not resolve
xadcntrl shows all services running
users can login OK

Any ideas folks?
