I recently inherited administration of a small SharePoint site (WSS v3). Currently, the 'Search' function only searches file/folder names, not file content. I have installed the Microsoft Office 2010 Filter Pack on the server, and configured the Windows SharePoint Services Search Service settings to index every 5 minutes. Both the Service Account and Content Access Account have been set to the credentials for a domain admin. I have also tried manually forcing indexing by running stsadm -o spsearch -action fullcrawlstart from the appropriate directory. This gives no error, but doesn't seem to have any effect. The event viewer shows Event 17137 every few minutes, sometimes from the domain admin account, sometimes from random accounts; this message's source appears to be the SharePoint SQL database but no details are given. (It says you may not have the necessary registration information or DLL files to display messages from a remote computer, even though I'm doing this on the server itself.) I also have a sprinkling of red-flagged 17828 errors and 'failure audits,' all of which are equally unhelpful since they give the same message about not having the DLL/registry setting to see the actual message. All other features on WSS are working (as far as I and the users can tell) except for the indexing of content.
Any idea what I need to do to get indexing working?
