A Windows Server 2003-based computer that uses the Storport storage driver stops responding when you try to restart or shut down the computer

A Windows Server 2003-based computer may stop responding when you try to restart it or shut it down. This problem occurs if the following conditions are true:

• The computer is part of a storage area network (SAN).
• The computer uses the Microsoft Storport storage driver for the QLogic QL2300 host bus adapter (HBA) driver.

Typically, this problem occurs on the following computer models:

• HP DL380 G5
• HP BL460C G1

This problem may occur if you use version 5.2.3790.2723 of the Storport driver or a later version. These drivers include a change in which there is no shutdown notification for a third-party miniport driver. In this case, the third-party miniport driver cannot complete all input and output operations before the shutdown occurs.

To resolve this problem, follow these steps:

1. Install Windows Server 2003 Service Pack 2 (SP2). For more information, click the following article number to view the article in the Microsoft Knowledge Base:
