An error occurred on database "NORTHWIND\NORTHWIND". Function name or description of problem: Restrict/SetSearchCriteria Error: 1162 Warning: fail to apply search optimization to folder (FID 4-140D5) Retrying without optimization. I've read this may be ignorable, or caused by AV locking. We are running Sophos, current version.Windows Search is installed on this server generating MAPI search errors, I've turned that off could itsMAPI calls have anything to do with this either? Should I just isinteg the db and defrag ?Thanks for the advice! Sean TrimmTrimm Managed Network Services, DBA

Hi,And is the AV scanner a file scanner ? If so then exclude the database and log file directories.About the repair you can try it but please make a backup before you do it.Regards,Johanblog: www.johanveldhuis.nl
