Symptoms
Consider the following scenario: You have a Peripheral Component Interconnect (PCI) Express interface that supports the “hot plugging” feature on a Windows Server 2008-based computer or on a Windows Vista-based computer.You connect a device to the root port of the PCI Express interface.You use the “hot plugging” feature to add or to remove a PCI Express device on the computer.In this scenario, the Windows Server 2008-based computer or the Windows Vista-based computer may be restarted unexpectedly. Additionally, you receive the following error message:
0x00000124Note When you restart a Windows Server 2008-based computer or a Windows Vista-based computer, the issue may also occur if a PCI device is connected to the root port of the PCI-Express bus on the computer.
Resolution
This issue occurs because resource rebalancing is triggered after you hot plug a PCI device. During the rebalancing process, the system does not configure the Max Payload Size value correctly on the root port of the PCI Express bus. The incorrect value causes a mismatch between the root port of the PCI Express bus and the device on the PCI Express bus. Therefore, the operating system triggers a Machine Check Architecture (MCA) exception, and the operating system returns a “0×00000124” exception.
Symptoms
Consider the following scenario that occurs when you use Microsoft SQL Server 2008 Reporting Services:You try to access Report Manager or Report Server by using a URL that resembles one of the following URLs:
http://name/reports
https://name/reportsNote The name placeholder is not the name of the computer on which Report Server and Report Manager are deployed.However, the DNS Client service, the computer’s hosts header files, or the computer’s Lmhosts files that are located in the C:\WINDOWS\system32\drivers\etc folder are configured to send requests to name back to the report server computer.You try to access Report Server directly by using one of the following URLs. When you do this, you experience no problems. Additionally, you can browse the Report Server namespace and view all reports by using the following URLs:
http://name/reportserver
https://name/reportserverThe ReportServerUrl element is specified in the Rsreportserver.config file and is set to resemble one of the following URLs:
http://name/reportserver
https://name/reportserverYou try toaccess Report Manager by using one of the following URLs:
http://name/reports
https://name/reportsIn this scenario, you receive what resembles the Report Manager user interface. However, where you expect to see a list of reports, you receive the following error message:
HTTP 401.1 – Unauthorized: Logon FailedNote If you use SharePoint Integrated mode, you receive the error message on the SharePoint Webpages. The symptoms in this scenario are most likely to occur when one of the following conditions is true: Reporting Services is deployed in a scale-out deployment.Reporting Services is accessed by using a user-friendly name that does not match the computer name.
Resolution
This problem occurs because Windows includes a loopback check security feature that helps prevent reflection attacks on your computer. Therefore, authentication fails if the FQDN or the custom host header that you use does not match the local computer name.
Symptoms
Consider the following scenario:You add a computer that is running Windows Server 2008 Server Core to a Windows Server 2008 domain.You enable one or more Group Policy preferences in a Group Policy object (GPO). You deploy this GPO to the computer.At an elevated command prompt on the computer, you run the gpupdate /force command.In this scenario, the Group Policy preferences are applied successfully. However, the following warning message is logged in the Application log:

Description:
Windows could not record the Resultant Set of Policy (RSoP) information for the Group Policy extension Group Policy Folders. Group Policy settings successfully applied to the computer or user; however, management tools may not report accurately.These two event logs indicate that the following files are missing on the computer:%SYSTEMROOT%\system32\wbem\polprocl.mof%SYSTEMROOT%\system32\wbem\en-US\polprocl.mflNote This problem occurs inWindows Server 2008 Service Pack 2 (SP2) Server Core and Windows Server 2008 Server Core.
Resolution
This problem occurs because the Windows Server 2008 Server Core Setup program does not copy the two missing files to the computer during the installation process.
