Change Hash value of favicon.ico

I always open a lot of tabs for NC forum and my NC server on my browser. As they use the same favicon.ico, it is quite confusing and sometime disturbing. So, I replace the core/img/favicon.ico with another graphic. Then, I receive the following error message.

How can I fix it?
