Hi All,

Can anyone please explains to me as to why my file server is running very slow and then when I open the resource manager, the highest Disk I/O Read per second is more than 113 MB/s for C:\Windows\SoftwareDistribution\DataStore\DataStore.edb [Image: svchost.exe (netsvcs)] ?

and also the following Event is logged:

".  The open file operation will fail with error -1032 (0xfffffbf8).

So I wonder what could be the problem here ?

anything in the softwaredistribution folder is related to windows update
i would stop the windows update service and delete all files and folders in that softwaredistribution folder then restart windows update service.  files in there will be created by the service automatically

try running windows update again and see if there are any errors; monitor for a bit and see if the problem persists

Seth,

The windows update is controlled by SCCM 2007 and it is happening during the working hours.

Why the windows update needs to write something to the database .EDB ?
