SYMPTOMS
A Microsoft Windows Server 2003-based computer stops responding during startup after you install Windows Server 2003 Service Pack 1 (SP1). You see a black screen when the system stops responding.

<div class="cause_section">

CAUSE
This problem occurs if the following conditions are true:
 * One of the disks has a &quot;00000000&quot; signature.
 * This disk is write-disabled or read-only.

When the Plug and Play manager tries to enumerate a disk, the Plug and Play manager puts an exclusive hold on the disk. In this case, when the Plug and Play manager tries to write a signature to the disk, the Plug and Play manager receives a STATUS_MEDIA_WRITE_PROTECTED error. This error causes the Plug and Play manager to add another work item. A loop occurs because the disk is not released.

<div class="resolution_section">

RESOLUTION
Add a signature to the disk before you make the disk write-disabled or read-only. To do this, make the disk write-enabled before you start the system. For more information about disk features, contact the hardware vendor.

<div class="status_section">

STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the &quot;Applies to&quot; section.
