I tried to configure MySQL server 5.5 on Windows and this is what I got:
mysql-server-5.5-winx64:56 - Attempting to update security settings. mysql-server-5.5-winx64:100 - Unable to update security settings. Unable to connect to any of the specified MySQL hosts. mysql-server-5.5-winx64:62 - Attempting to verify command-line client shortcut.
Any thoughts? I found this article on it, but I'm not really sure what to do. I tried getting random processes to work but it didn't seem to change much.
