Problems Logging into Oracle Enterprise Manager

Recently I needed to login to the Oracle Enterprise Manager on an Oracle 10g Standard One server, but received a message stating that my username and or password was invalid. What made this more confusing was the fact that, using the same username and password I was able to login via the command-line SQL*Plus client.

The problem seems to have been a synchronization issue with the password file that Enterprise Manger uses. The way to fix this is to login to the Oracle database via the SQL*Plus client, then set the SYS password using:
alter user sys identified by ""
