Symptoms
On a Microsoft Windows XP-, Microsoft Windows Server 2003-, Microsoft Windows Vista- and Microsoft Windows Server 2008-based computer, if you attempt to shutdown the computer when you are running an application that uses the Remote Access Connection Manager, or the Telephony service, the Remote Access Connection Manager or the Telephony service may not be stopped properly and an unexpected error may occur.
In addition, even if you try to stop the Remote Access Connection Manager service or the Telephony service, the following error massage is displayed and the service cannot be stopped.

When running the Remote Access Connection Manager service Windows XP and Windows Server 2003

Cannot stop the Remote Access Connection Manager service on a local computer.
The service did not return an error. This could be an internal Windows error or an internal service error.
If the problem persists, contact your system administrator. On Windows Vista and Windows Server 2008, you cannot click the Stop button once the service is in use and an error message will not be displayed.
When running the Telephony service Windows XP and Windows Server 2003

Cannot stop the Telephony service on a local computer.
Error 1053:The service did not respond to the start or control request in a timely fashion. Windows Vista and Windows Server 2008

Cannot stop the Telephony service on a local computer.
Error 1052:The requested control is not valid for this service.
Resolution
Because the Remote Access Connection Manager or the Telephony service cannot be stopped properly, an application that uses these services may return an unexpected error.

Symptoms
After you restart Windows Server 2008, the following event may be logged in the System log:

Log Name:System
Source:storflt
Event ID:5
Level:Warning
Task Category:None
Message:The Virtual Storage Filter Driver is disabled through the registry. It is inactive for all disk drives.
Resolution
This event is logged when one of the following scenarios is true:The virtual storage filter driver cannot attach to the virtual storage device. The virtual storage filter driver is included in Windows Server 2008. This driver optimizes the performance of disk I/O if Windows Server 2008 is running on a Microsoft Hyper-V Server.Windows Server 2008 is installed as the host operating system or as the guest operating system before the most recent version of Hyper-V Server is installed.

Symptoms
Consider the following scenario:You are running a Windows XP-based computer.You create an End User Defined Character (EUDC) font.You deploy the EUDC font to a Windows Vista-based computer or to a Windows Server 2008-based computer. In this scenario, you cannot enter the EUDC characters by using the Pinyin (phonetic) Input Method Editor (IME) or the Changjie IME.
This issue also occurs if you upgrade a Windows XP-based computer to Windows Vista.
Resolution
This problem occurs because the format ofEUDC-related files in Windows Vista differs from the format of EUDC-related files in Windows XP. Therefore, the EUDC-related files that were created in Windows XP are notrecognized, and they cannot be automatically migrated to Windows Vista.

Symptoms
When you run the System Preparation tool (Sysprep.exe) on a computer that is running Windows Vista or Windows Server 2008,a folder is created in or copied to the following location:
C:\users\public\documents\dataHowever, the access control lists (ACLs) forthis folder are out of order.
For example, assume that you create a folder under C:\users\public\documents\data. Then, you right-click the folder, you click Properties, and then you click the Security tab. In this scenario, the Security dialog box does not appear. Instead, youreceive the following error message:

The permissions on %foldername% are incorrectly ordered, which may cause some entries to be ineffective.

Symptoms
Consider the following scenario:You install the Terminal Services role on a computer that is running Windows Server 2008.You start a Terminal Services session with the terminal server from a computer that is running Windows 7 Service Pack 1 (SP1) or Windows Server 2008 R2 Service Pack 1 (SP1). You try to shadow another Terminal Services session in the Terminal Services session.Your shadow request is accepted by the user account in the Terminal Services session that you want to shadow.In this scenario, the remote control operation fails. Additionally, the shadowed Terminal Services session is disconnected, and the user account in the shadowed Terminal Services session receives one of the following error messages:
Error message 1

Your Remote Desktop session has ended. Your network administrator might have ended the connection. Try connecting again, or contact technical support for assistanceError message 2

The remote session to the remote computer was ended by means of an administration tool. Your administrator might have ended your connectionAdditionally, an event that resembles the following is added to the System log on the terminal server:
Log Name:System
Source:TermDD
Date:<date>
Event ID:50
Task Category: None
Level:Error
Keywords:Classic
User:N/A
Computer:computername.domain.com
Description:
The RDP protocol component “DATA ENCRYPTION” detected an error in the protocol stream and has disconnected the client.

Resolution
The issue occurs because one input buffer size is insufficient.
The RemoteFX feature is introduced in Service Pack 1 for Windows Server 2008 R2 and for Windows 7. This feature causes one input buffer that is used by Windows Server 2008 Terminal Server to be insufficient.

Symptoms
When you use Microsoft System Center Operations Manager 2007 to monitor system performance on Windows Server 2008-based computers, a memory leak occurs. Specifically, this memory leak occurs in the performance counters that are used by System Center Operations Manager 2007.
Note Any applications that use performance counters in Windows Server 2008 may also experience this problem.
Resolution
This problem occursbecause of a bug in the way that Windows Server 2008 manages allocated memory.
