Connect Internal asks for a password

I have inherited an Oracle 7.3 database on Solaris which I have to maintain. I have three instances dev, test and prod. These were created by a group which ahs left. When I use Server Manager Line Mode under Solaris for Oracle 7.3 I am asked for a password when I try to 'connect internal' to any of these instances.

If the instance is set to local then I am able to connect internal. What must be the reason for not being able to connect to the above instances. The UNIX user (oracle software owner - oracle) logging in to run svrmgrl is part of the dba group.

Also I cannot connect as SYSDBA via Enterprise Manager. I am unable to grant SYSDBA or SYSOPER privilege as no user seems to have thsi privilege.

This means that if an instance is up I am not able to shut it down In fact 'dbshut' does not continue after starting server manager.

Is it possible that ORAPWD utility was used to set passwords? Any other reasons?
