Question : domain active directory password policy

Is it possible to change the password policy in the domain active directory for one department and not affect the rest of the departments on the same domain?

Answer : domain active directory password policy

Not possible in a W2k3 AD; 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.
