We are having an annoying problem and are very new at using sharepoint.  We are setting up users with access to the sharepoint site.  The setting are saying that the passwords are set up to not expire.  the majority of our users only access this site once a month if not longer.  what is happening is that there passwords are expiring and have to be reset everytime these people try to get back into this site.  Is something overriding this control or do we have to set the users up in a different way.  Any advice would be appreciated.

Thanks

Cory
