Our DBAs reviewed the Microsoft documentation you referenced, modified the registry, and rebooted the OS. We've been beating up on the database without seeing the error so far. We'll keep at it for a while. -Kevin >>> Qingqing Zhou <zhouqq@xxxxxxxxxxxxxx> >>> On Wed, 16 Nov 2005, Kevin Grittner wrote: > Ran with this change.
