When you right-click a shared network folder or a shared network file on a Windows Vista-based computer or on a Windows Server 2008-based computer, and then you click Always Available Offline to pin the network resource, you cannot access the shared file or folder. This problem occurs if only part of the network resource is cached. Additionally, you receive an error message that resembles the following:

Access is denied.

If you synchronize the file or the folder, the synchronization operation is successful. However, you still cannot access the file or the folder.

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:

• On a Windows Vista-based computer, or on a Windows Server 2008-based computer, you run an application that uses the Open Database Connectivity (ODBC) API.
• The application uses the SQLSetConnectAttr function to set an attribute.
• You pass an SQL_NTS constant as the StringLength parameter to the SQLSetConnectAttr function.

In this scenario, an access violation may occur if you pass an INTEGER value to the ValuePtr parameter of the SQLSetConnectAttr function.

Note: This issue does not occur in Microsoft Windows 2000 Server, in Windows XP, or in Windows Server 2003.

When you use Remote Desktop Connection to connect to a Windows Vista-based computer, you receive an error message that resembles the following:

The requested session access is denied.

You open the root directory that contains offline files on a Windows Vista-based computer. When you try to synchronize the offline files with the file server for the first time, the synchronization is unsuccessful. In this situation, Windows Vista does not resume the synchronization. Additionally, when you click the offline files that are not synchronized, you receive an access denied message.

Note: When the synchronization is unsuccessful, Windows Vista creates broken branches of the synchronization tree.

When you run an application on a computer that has Windows Internet Explorer 7 installed, you receive an error message that resembles the following:

Access is denied

This problem occurs when you develop an application that starts new processes from an impersonated context.

Note: This problem does not occur on a computer that has Microsoft Internet Explorer 6 installed.

When you open a Web page that uses Secure Sockets Layer (SSL) in Microsoft Internet Explorer 6, an access violation may occur. Additionally, you may receive the following error message:

Microsoft Internet Explorer has encountered a problem and needs to close. We are sorry for the inconvenience.

Consider the following scenario:

• You develop an application that sends an IOCTL_SFFDISK_DEVICE_COMMAND request to a Secure Digital (SD) card.
• You compile the application on a 32-bit version of Windows Vista.

In this scenario, the application obtains a “Success” value from the SD card. However, when a 64-bit version of Windows Vista uses the Microsoft Windows-32-on-Windows-64 (WOW64) subsystem to run the 32-bit application, the application obtains the following error message from the SD card:

ERROR_ACCESS_DENIED

Consider the following scenario:

• In a version of a Microsoft operating system that is earlier than Windows Vista, you create two users, User A and User B.
• You add the two users to the local Administrators group.
• You use the User A account to log on to the computer, and then you create a new folder. For example, you create Folder F. Then, you add files or subfolders to Folder F.
• You grant Read access to Folder F only to the User A account.
• You log off the computer, and then you use the User B account to log on to the computer.
• You upgrade the computer to Windows Vista.
• You use the User A account to log on to the computer.

In this scenario, the User A account no longer has Read access to Folder F.

Consider the following scenario:

• You access rights-protected content by using a local user account.
• You use this local user account from a computer that is located outside the domain.

In this scenario, you are not prompted for your credentials to authenticate to the Windows Rights Management Services (RMS) server. Therefore, you cannot access the rights-protected content.

This problem typically occurs in scenarios in which you log on to a home computer that is running Windows Vista by using a local user account. Then, you use Microsoft Office Outlook Web Access (OWA) to access the e-mail account from your workplace. In this scenario, you may not be prompted for your credentials to access the RMS server.
