On Win2K the easiest way to hack your way back into the
database is to log on as local administrator then run 
orapwd utility to re-create the password file (change 
working directory to ORACLE_HOME/bin then type orapwd 
and you'll see the full syntax).
 
New password file should be created in such a way as to 
be compliant with (or following) Oracle's defaults (be
where Oracle expects to find it):

        ORACLE_HOME\database\PWD<YOUR_SID>.ora

If the password file was already there but you forgot 
the what that password is, rename existing password file 
to say PWD<YOUR_SID>.ora.old then create the new one:

orapwd file=C:\Oracle\Ora92\database\PWD<YOUR_SID>.ora 
         password=<YOUR_NEW_PWD>

Using SQL*Plus: 
        connect sys/<YOUR_NEW_PWD>@<YOUR_SERVICE> as sysdba
then 
        alter user sys identified by <YOUR_NEW_PWD>
to synchronize sys'es password in data dictionary.
After that - the business as usual.

Other way to achieve the same (hack back in) would be
to fiddle with pfile, sqlnet.ora, and local ORA_DBA group
in order to be able to use OS account to log on as SYSDBA
and then 'alter user sys...'. But this way is a pain 
compared to simply 'blowing up' the old password file,
creating the new one then re-synch-ing it.
