In 2012 you can use Fine Grained Passwords to do this.

Open ADAC from your DC and create a new password policy, then the group it applies to (e.g. Domain Users).

Here's a step by step:

Not going to be possible with Windows server "out of the box", however third party products exist that can do this. Here are a couple:

+1 for Anixis PPE.
It is also correct, what Malmensa says: not possible with built-in GPOs or fine grained password policies.

The other experts are correct about FGP, I misread and thought you only wanted to prevent passwords that consist of lowercase strings exclusively.
