Search Service Error

I'm getting the following error when I try to go into the "Content Sources" section of the Search Administrator in the SSP.

The search service is currently offline. Visit the Services on Server page in SharePoint Central Administration to verify whether the service is enabled. This might also be because an indexer move is in progress.

I know that the service is started, and that the index is not being moved.

The Crawl Status is Error.

I have reconfigured the Search, and still I get the same error. The account running the service has the correct security settings on the SQL Server.
