Set up and follow a regular maintenance program to ensure maximum performance and availability from Microsoft NNTP Service. The goal of regular maintenance is to identify and correct potential problems before they become real problems and affect your users.
Four types of maintenance functions make up the Microsoft NNTP Service maintenance program:
Performance counters enable you to monitor critical performance data for unusual values.
Microsoft® Internet Information Server (IIS) logs enable you to see who is using your news site and how they are using it.
The Microsoft NNTP Service rebuild capability enables you to update the indexes and the hash tables that keep track of articles posted to newsgroups.
