Windows SQLPLUS login error

Question

When attempting to login using Sqlplus
username = sys/ as sysdba
passwd = *********
Host String = orcl
The screen runs some lines on the window so quick and then terminates?
However If I login as system with out trying to use sysdba connection it works.
Windows 2003 server
Oracle 10G.2
Am I doing something wrong??

In order to allow remote connections as SYSDBA, you need to do the following:
1. Create a password file for your database(s) using the 'orapwd'
utility.
2. Set the init parameter REMOTE_LOGIN_PASSWORDFILE to either
EXCLUSIVE or SHARED.
3. Restart the database.
4. (Re)set the passwords for SYS and any other users to whom you have
granted SYSDBA privilege. (Note, if using a SHARED password file,
you effectively cannot grant SYSDBA to anybody other than SYS.)
5. For remote SYSDBA sessions, always authenticate with a
USERNAME/PASSWORD. This is mandatory for SYSDBA, regardless of
the setting for OS/remote-OS authentication.
After you do this, you'll be able to connect to databases using
a connect string of the form:
CONNECT SYS/*******@my_db.my_domain AS SYSDBA
By the way, SETTING REMOTE_OS_AUTHENT=TRUE is extremely dangerous
and should never be done under any circumstances. It won't work for
sysdba sessions anyways. If you have followed earlier advice to
enable that feature, TURN IT OFF NOW!
Not sure if this is Windows
