MOSS Configuration Rules are specifically designed for Microsoft Office SharePoint Server (as opposed to WSS – Windows SharePoint Services).

These Rules deal with the results of SharePoint search crawls – excessive values of these properties may degrade the performance of your SharePoint environment.

These Rules are also broken down into the following types:

Excessive Keyword Rules

These Rules check if the number of keywords per site exceed a certain threshold.

Excessive Properties Rules

These Rules check if the number of managed properties exceed a certain threshold. Managed Properties are mapped properties such as the author, title or subject of a document.

Excessive SSPs Rules

These Rules check if the number of SSPs exceed a certain threshold. SSP stands for Shared Service Providers. SSPs allow SharePoint administrators to centrally manage and share certain services between various sites – such as profile information obtained from an Active Directory.

Excessive User Profile Rules

These Rules check if the number of user profiles exceed a certain threshold.
