There is no method, through WHS, of setting the passwords to expire. The rational, I would expect, is that this is a 'home' network and consequently not as vulnerable to third parties.
Although WHS is based on Server 2003, (and it's security infrastructure), it is recommended that the only changes should be done through the Console, otherwise it can lead to major problems for WHS. This has resulted in re-installs being required in some cases.
