I have recurring error 3760 in the Event Log. I have a WSS 3.0 site on a Windows Server 2003 SP2 and SQL Server 2005 Standard Edition. I also see related events 18456 and 2436 that occur right before event 3760. It appears these were caused by a security update. The "Windows SharePoint Services Search" service is using 'PBTF\SvcMOSS' account. Could I reset this account? What else could be cause this problem?
