I have ...
Oracle 10.1.0.2.0 on Solaris 64bits

sqlnet.ora > SQLNET.AUTHENTICATION_SERVICES= (NTS)
sqlnet.ora > NAMES.DIRECTORY_PATH= (TNSNAMES)
sqlnet.ora > NAMES.DEFAULT_DOMAIN = world

id> uid=1100(oracle) gid=200(dba)
init...ora > remote_login_passwordfile = exclusive

orapwd file=$ORACLE_HOME/dbs/orapw$ORACLE_SID password=abcdef1

I can connect with sqlplus /nolog ...
connect sys/abcdef1 as sysdba
But the following wont work
SQL> connect / as sysdba
ERROR:
ORA-01031: insufficient privileges

I've even rebuilt the password file by

1.Shutdown immediate
2.issue the orapwd to build a new password file
3.startup the database (after connecting sys/abcdef1 as sysdba)
4.issue alter user sys identified by abcdef1;
5.issue grant sysdba to sys;

and the connect / as sysdba still generates the ORA-1031

How can I fix this problem ?
(or determine that I must re-install the Oracle software)

TIA Note: This is the information in $ORACLE_HOME/root.sh ... ORACLE_USER=oracle
