Hi Kent,

In an AD environment, you must install the same password
filter on all domain controllers, otherwise you'll end up
with weird results, since there is no communication
between DCs on this. What happens is when the client sends
a password change to its DC, that DC will allow/deny the
password change based on the filter installed on that DC.
If the password change is approved on that DC, the DC then
pushes out the modified object through normal AD
replication. Incoming replication from another DC does not
trigger password filters. The only thing that triggers the
filter is a password change, or password set done directly
against that DC.

Best,
