SYMPTOMS
When the Plug and Play feature starts on a Microsoft Windows Server 2003-based computer, Plug and Play may stop responding.



CAUSE
This problem may occur if a SCSI inquiry occurs at the same time that the Plug and Play scan starts. If a SCSI device has a resource issue, a rebalance of available resources occurs and causes a Query Stop command to be sent to all devices. The SCSIPORT system file permits the Query Stop command to occur, even if a Plug and Play scan is running. Therefore, the Plug and Play scan cannot be completed.
