SYMPTOMS
When you upgrade from Microsoft Windows 2000 to Microsoft Windows Server 2003, the computer may stop responding (hang) after you restart for the first time. You experience this problem on computers where there are multiple paths to the system disk.



CAUSE
This problem may occur if the computer uses a high-availability configuration. Such configurations include Storage Area Network (SAN), network-attached storage, Cluster service, and Network Load Balancing (NLB). The problem occurs when the following conditions are true:
 * The system disk becomes unavailable when Partition Manager (PartMgr.sys) disables access to redundant multiple paths.
 * Information about this condition is not communicated to the Windows text mode Setup program (Setupdd.sys).

In this scenario, Setupdd.sys tries to use an incorrect path to connect to the system disk. When Setupdd.sys tries to use this incorrect path, you experience the problem that is described in the &quot;Symptoms&quot; section.



RESOLUTION
To resolve this problem, use integrated Windows installation source files to install Windows Server 2003 Service Pack 1 (SP1).
