An error occurred in the Microsoft SharePoint Portal Server Search (SharePointPSSearch) service. The content index was not propagated to one of the search servers, and search capacity will be reduced.
To resolve this issue execute the following steps:
Look in the Application event log on the Search Server for related events and information. The Application event log can be viewed through the Event Viewer snap-in which can be found in the Computer Management console.
Start Computer Management Console
Address any issues in the event log that are responsible for this failure and then propagate the content index to the server.
For information about the SharePointPSSearch service and propagating content indexes, see the Microsoft Office SharePoint Portal Server 2003 Administrator's Guide.
