Consider the following scenario:

• You run a service on a member server that is running Windows Server 2008 or Windows Vista in an Active Directory domain.
• The service runs under the Network Service account.
• The service calls the IADsUser::ChangePassword method to change the machine account password of the member server.

In this scenario, the Lsass.exe process crashes because of an access violation error. You receive the following error message:

You are about to be logged off Windows has encountered a critical problem and will restart automatically in one minute. Please save your work now.

After the computer restarts, you find that the following event is logged in the event log:

Event Type: Information
Event Source: Application Popup
Event Category: None

Consider the following scenario:

• You have a computer that is running Windows Vista or Windows Vista Service Pack 1.
• You have other computer that is running Windows Vista or Windows Server 2008.
• Both of computers are in a same workgroup.

In this scenario, the Credentials Manager (CredMan) service does not save credentials when you try to map a drive by using a net use command together with the /savecred option.

Note: This behavior differs from Windows Server 2003 and Windows XP.

After beginning an update process, the updates are not installed. An event such as the following may be logged:

Consider the following scenario. You configure a computer that is running Windows Vista or Windows Server 2008 to use the pen service (Wisptis.exe). Then, you restart the computer. In this scenario, an access violation occurs during startup. When the access violation occurs, the Wisptis.exe process exits, and you receive an error message that resembles the following:

Microsoft Tablet PC Input Component was closed

Consider the following scenario:

• You have a Windows Server 2008-based print server.
• This print server has many Windows Vista-based printer clients.

In this scenario, the memory usage of the Print Spooler service increases over time. For example, assume that you have several thousand printer clients that connect to the print server. Eventually, the print server becomes unresponsive, and you must restart the server to recover from this problem.

Consider the following scenario:

• You create a managed service that uses the Microsoft .NET Framework 2.0.
• You run the managed service on a computer that is running the .NET Framework 2.0.

In this scenario, the managed service is not stopped in a timely manner on the computer when the operating system shuts down. Therefore, you may experience delays when the operating system shuts down.

On a computer that is running Windows Vista, an Indexing Service query that uses the LIKE predicate returns an incorrect result. For example, when you use the following query clause to query for files whose names contain the “doc” string, the result may include some files whose names do not contain the “doc” string.

SELECT Filename FROM Scope() WHERE filename LIKE '%doc%'

Note: This problem does not occur on a computer that is running Windows XP.

When you start a Windows Vista-based computer that has more than one TV tuner, you receive the following error message:

Windows Media Center Receiver Service stopped working and was closed. A problem caused the application to stop working correctly. Windows will notify you if a solution is available.

Also, the Windows Media Center Receiver service (Ehrecvr.exe) may stop unexpectedly.
