11g allows for case-sensitive passwords, so firstly check the password TIGER (and maybe Tiger)

since the database is on your local machine, easiest is to connect to it using os authentication and reset the password to a known value and then use that to connect using the tool you want. On windows you can do this in the *nix style. First find where your oracle rdbms installation is located and assign that value to the ORACLE_HOME environment variable. Use the commandline tool.

ORACLE_HOME=d:\somwehere\on\your\disk
PATH=%ORACLE_HOME%\bin
ORACLE_SID=ORCL
sqlplus "/ as sysdba"
alter user scott identified by koffie;

(make sure you remember the password this time, including case as since 11g passwords are case sensitive.) sqlplus should be in %ORACLE_HOME%\bin. Check this before.

I hope this helps.

Is the account unlocked? As a privileged (SYS account) try running:

 SELECT USERNAME, ACCOUNT_STATUS
 FROM DBA_USERS
 WHERE USERNAME = 'SCOTT';

If the account is locked, try:

ALTER USER SCOTT ACCOUNT UNLOCK;

Also it appears you are trying to connect to the database as SYSDBA using the SCOTT account. I believe by default this schema lacks the necessary account privileges. Try logging in as SCOTT/TIGER connecting as "normal", not "sysdba".

Use: orapwd file=$ORACLE_HOME/dbs/orapw$ORACLE_SID password=Euro2016 entries=5 grant sysdba to scott;

Now you can connect...
