Title: How to Create an Expiration Policy for a Newsgroup in NNTP in Windows Server 2003

Objective: The objective of this demo is to teach you how to create an expiration policy for a newsgroup in NNTP in Windows Server 2003. Expiration policies can be set separately for each virtual server. Expiration policies specify the article age limit for newsgroups; they also specify the newsgroups to which the policy applies. If a newsgroup is assigned to more than one expiration policy, the more restrictive policy applies.
