[xces]

Heya i have executed this query:
GRANT ALL PRIVILEGES ON MySQL TO root@'10.0.0.%';
update user set Password=password('MyNewPassword') where 'User'='root';

and all goes ok;

But i can't connect to MySQL with "MyNewPassword" but i CAN connect with an empty one.. Anybody knows what's wrong?

The problem was the 'root@' part... Changed it to 'peter@' and it all worked...
