In DOS box, execute:
set ORACLE_SID=<your database sid>
set ORACLE_HOME=<your database home>
sqlplus user1/...
But there are several inconsistencies in your post:
1/
SQL*Plus: Release 10.1.0.4.2
Connected to: Oracle Database 10g Express Edition Release 10.2.0.1.0
Have you 2 Oracle homes on your server?
2/
SQL> create user user1 identified by user1;
...
So your already connected to be able to create a user but as you can't connect locally with the new user this means you first connected through SQL*Net that is using an alias.
So you should be able to connect to the new user (after grant CREATE SESSION to it) with the same alias, that is in the same way you first connected.
Regards
Michel

Okay let me clear it.
i went to star menu on my windows7 >> Applicatoin Development>>sqlplus>> now it is promting me for a user and password, and i gave it <system> in the username box, <shaikh> for its password, and <myNSN> for the host string. Then it connect me to the Database through the <system> user now i have created another user and i cant login to that user.

Yes, i can connect with the server through the SYSTEM user, and i am not able to connect through the SYS user because i dont know its password. And i think SYSTEM does not has the right to grant a user sysdba privilege.
