Hi,Please start with the following things:- update the drivers and firmware of your storage environment- run the Exbpa tool to check your system and apply the tips you will get from the tool- ensure that the correct directories are excluded for virusscanningTo change the maintenance schedule perform the following steps:- Open Exchange System Manager- Expand Servers, and then expand the server that you want to work with. - Expand the storage group that you want to work with.- Right-click the store that you want to work with, and then click Properties.-- On the Database tab, click Maintenance interval and click a new interval, or click Customize to create a custom schedule.

Hello,Please update as suggested by Johan and addition to The failure was due to the issue that exchange was unable to read from the file. This was a result of the failure of communication with the disk, which can be either due to a hardware issue or a network issue. Hence it would be better to check with your hardware vendor if there are any logging on the hardware side to see what is happening. You have Symantec? If yes... get back to symantec for update :)Ref:Exchange Server 2003 and Exchange 2000 Server information store maintenance and online defragmentationhttp://support.microsoft.com/kb/324358JeremyK's [MSFT] WebLoghttp://blogs.msdn.com/jeremyk/archive/2004/06/12/154283.aspxArun Kumar | MCSE - 2K3 + Messaging | ITIL-F V3
