Group Policy - PAssword does not work

Hi,

I have a group policy Issus and I cannot seems to find out the Issus.

I have setup a password policy at the root of the top level domain. ( remember 5 last password, Minimum 6 caractere )

I have check all my 13 DC for Replication Error and Dcdiag and everything is clean no Errors.

When I do n rsop.msc on a desktop I do see the policy and the source GPO does match the name of the policy.

If I tried to change my password and put the same or 2 digit it will let me know even if the policy says remember 5 last and minimum6 caractere. If I do a gpupdate /force everything is being applied and no errors.

Any tought ?

THanks
