Receiving "TNSListener protocol adapter error" during installation

I'm installing Oracle 10g on a Win2K Server box. The installation acts flaky when trying to configure the database. It gives me "ORA12560: TNSListener protocol adapter error."

I'm installing Oracle 10g on a Win2K Server box. The installation acts flaky when trying to configure the database. It gives me "ORA12560: TNSListener protocol adapter error." I ignore the error and finish the installation. When I reboot the box none of the Oracle services start. I tried to restart them but I receive the same error.
It's difficult to say exactly what the problem is here. It could be that your ORACLE_SID and ORACLE_HOME are not set correctly. The problem may also stem from not having the appropriate privileges at the OS level. You must connect to the server with an appropriately privileged account. If you do not have operating system authentication, you will need to provide a username and password that have SYSDBA privileges.

Verify that the SID name you have chosen for your database does not contain a non-alphanumeric character such as an underscore or a dash. The SID can only contain alphanumeric characters.

Finally, check for any log files in $ORACLE_HOMEassistantsdbcalogs if you are using the Database Creation Assistant. Log files may help to pinpoint the source of this problem.
