Password Policy through GP in 2003

I haev 2003 Active Directory domain and i have a Password Policy that should force the user to change his password every 140 days. For some reason it comes up every aprox. 40 days. I could figure it out why.
There are some other policy that applies to the domain but nothing related to a password. Any help to troubleshoot thins will be appreciated.
Thank you,
AV
