Password weaknesses with LAN Manager

Windows security expert Kevin Beaver answers a user's question about LM hashes and fixing the password weaknesses that come with them.

I've heard there is a Windows NT server security issue involving LM hashes and passwords. Can you tell me more about this and how to fix it?
LAN Manager (LM) hashes are an older and weaker method of storing/protecting Windows passwords. There's a further explanation here as well as in my Hacking For Dummies chapter on hacking passwords.
