Password history and length: Group Policy

I have set the following policy...
Computer configuration > Windows Settings > Security Settings > Account Policies/Password Policy
Enforce password history = 8
Maximum password age = 45
Minimum password age = 30
Minimum password length = 8

However, I have just tried to change a password on a user account to what was the old password, it allowed me to do so. I also tried changing the user's password to less than 8 characters, this also succeeded.

I've ran rsop under the users account and the group policy settings appear to be in place.

We are running a 2003 forest. The client machine I attempted this on was a Windows 7 machine, the user account has domain administrator access (it's actually my own personal account)

Why have these restrictions not taken affect?

Probably because the policy you're testing this with is not linked to the domain root, or there's another GPO linked to the domain root with a higher priority in which password policy settings are defined, or because inheritance to the OU DOmain Controllers is disabled.
In a W2k3 AD domain, you can only have *one* password policy, it *has* to be linked to the *domain* *root*, and it *has* to be applied to the DCs.
Fine-grained password policies are only possible in a W2k8 AD, or with 3rd-party tools like from http://www.anixis.com/ or http://www.specopssoft.com/
Password policies applied to an OU will only influence *local* accounts on the computers in this OU.

enable additionally password complexity in the same node. Then check if you modified those settings in Default Domain Policy. Windows 2003 doesn't allow having more that 1 password policy for domain. Each additional policy will be rejected. The only one taking effect is set at domain level (Default Domain Policy)

Of course my second part of answer is described by oBdA (sorry I didn't see it before) and he's right.
