Running a defrag will not help and may very well hurt. How large are your stores? What is the hardware of the disks? How often is online maintenance completing? Regards, Michael B.

The box is an IBM 2.4 Ghz, 4gig ram supporting 500 users. The software is windows 2003 enterprise. Running performance monitor gave disk queue length of around 10 on the stores volume - sometimes more. Running disk defrag utility on stores volume gave volume fragmentation as 49% and file fragmentation as 98%. My question is - can you use windows defrag utility to clean this up or is there a better third party utility to do the job or am I looking in the wrong area for the poor performance? ~ Ninja Email Security with Cloudmark Spam Engine Gets Image Spam ~ ~ http://www.sunbeltsoftware.com/Ninja ~ ~ Ninja Email Security with Cloudmark Spam Engine Gets Image Spam ~ ~ http://www.sunbeltsoftware.com/Ninja ~ ~ Ninja Email Security with Cloudmark Spam Engine Gets Image Spam ~ ~ http://www.sunbeltsoftware.com/Ninja ~
