Make the OS user to OSDBA group.
And then,

conn / as sysdba
alter user username_here identified by new_password;

Addition with Arju suggestion ...
also set SQLNET.AUTHENTICATION_SERVICES=(NTS) in sqlnet.ora file
Located:$ORACLE_HOME/network/admin directory.
Default value is NTS but if NONE is set then change it.
