After some system changes, e.g. replacing the motherboard, in the server, trying to connect or startup the database fails.
The service is running, but you are unable to connect as sysdba using a domain account:

SQL> connect / as sysdba
ORA-01041: internal error. hostdef extension doesn't exist

SQL> startup
ORA-24324: service handle not initialized
ORA-24323: value not allowed
ORA-01041: internal error. hostdef extension doesn't exist

A domain administrator account is used to connect.  If the local system account is used, the connection as sysdba works fine.
