normaly it should import the client when you do a local installation or remote install over dp gui.
i would check the following:
- can the client resolve the cell server fqdn?
- check following regkey on the client: HKEY_LOCAL_MACHINE\SOFTWARE\Hewlett-Packard\OpenView\OmniBackII\Site -> under cellserver is the correct server specified?
- try to manually import the client after installation (import clients in clients tab)
