Working with WC Pwd Policy (Pwd Expiration)

Dear Guys,

Assume a case where where WC is not integrated with AD , and the pwd policy management  policy (Pwd Auro-Expiration for 1 month ) is set up in Windchill-DS . When a users fails to change the pwd , his account is automatically locked. And it causes an over-head for the Admin tochange the pwd for the failed users(s) .. is there a way to downsize the effort ? meaning like sending mail with random pwd to the Users automatically after the pwd expiration ?

Any other suggestions or ideas pls ?

Regards,
