Consider the following scenario:

• On a computer that is running Windows Vista or Windows Server 2008, you try to access a file on a Web Distributed Authoring and Versioning (WebDAV) server.
• This WebDAV server is located on an external network.
• You access the WebDAV server by using a proxy server that requires authentication.

Before you can open the file in this scenario, you are prompted for authentication four times. You expect to be prompted for authentication only two times.

Note: You expect to be prompted to authenticate one time against the proxy server and the other time against the WebDAV server.

The government of Egypt has announced a new daylight saving time end date for Egypt for the year 2008. The new time zone information is as follows:

• Daylight saving time starts at 23:59:59 on the last Thursday of April 2008.
• Daylight saving time ends at 23:59:59 on the last Thursday of August 2008.

A hotfix is available to update the daylight saving time for the (GMT+02:00) Cairo time zone for Windows Vista-based, Windows Server 2008-based, Windows XP-based, and Windows Server 2003-based computers.

Consider the following scenario:

• In a network environment, you enable the Delete cached copies of roaming profiles Group Policy setting in a particular domain.
• In this domain, you configure some user accounts to use a mandatory user profile.
• You log on to the domain by using a user account that uses the mandatory user profile from a client computer that is running Windows Vista or Windows Server 2008.
• You log off the computer.

However, if you log on to the domain from this client computer by using any other user account, you notice that the mandatory user profile is not deleted from the %SystemDrive%\Users directory as expected.

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

When you enroll a certificate on a computer that is running Windows Vista or that is running Windows Server 2008, you are prompted to insert a smart card even though a smart card is already inserted. After you unplug your smart card and then plug it in again, the certificate enrollment process continues successfully.

However, if the smart card and the reader are integrated into one unit, you cannot unplug the smart card. For example, if you use a USB token device as a smart card, the certificate enrollment process does not continue even after you unplug and then plug in the USB token device. Therefore, the certificate enrollment fails.

When you put a Windows Vista-based computer or a Windows Server 2008-based computer into hibernation, the system may crash. Additionally, you may receive a Stop error message that resembles one of the following messages:

• STOP 0x000000A0 (parameter1, parameter2, parameter3, parameter4)
  INTERNAL_POWER_ERROR (a0)
• STOP 0x0000007a (parameter1, parameter2, parameter3, parameter4)
  KERNEL_DATA_INPAGE_ERROR
• STOP 0×00000077 (parameter1, parameter2, parameter3, parameter4)
  KERNEL_STACK_INPAGE_ERROR

This problem occurs only occasionally. Currently, the problem is found on computers that have SB700 Southbridge chipsets installed.

On a Windows-based computer, devices that stream data over more than two isochronous channels by using IEEE 1394 connections may have choppy or distorted output. Typically, the issue occurs when multiple instances of isochronous data, such as audio data and video data, are streamed over the IEEE 1394 connections.

Note: This problem may also occur on a single physical device that has multiple channels of isochronous data. For example, this problem may also occur on an audio mixing board that outputs multiple audio channels over separate isochronous channels.

For example, you may have multiple digital video cameras, audio input devices, or both, that are connected to the computer by using the IEEE 1394 connections. In this case, streaming video that is output from the digital video cameras may appear choppy and may not have a smooth and steady frame rate. Steaming audio from the audio devices may have distorted sound.

On a Windows Vista SP1-based computer or on a Windows Server 2008-based computer, you visit a Web page by using Internet Explorer 8 Beta. When you try to play a video in this Web page by using embedded RealNetworks RealPlayer 11, you receive the following message even though RealPlayer has been installed successfully on the computer:

In order to play this video, you need the current version of RealPlayer.
Please click below to download the free RealPlayer.

Note: This problem does not occur if the computer is running the release-to-market (RTM) version of Windows Vista.

You are running a Windows Vista-based or a Windows Server 2008-based computer that has an internal USB device installed. When the computer enters sleep mode, the computer may stop responding. Additionally, you may receive the following Stop error:

Stop 0x000000FE (00000008, 00000006, 00000002, parameter4)
BUGCODE_USB_DRIVER

Note: In this error message, the value of the Parameter4 may vary.

This article describes a hotfix rollup package that is available for the Traditional and Simplified Chinese Input Method Editors (IMEs) in Windows Vista and in Windows Server 2008. This hotfix provides the following features and fixes:

• The ChangJie, Quick, and Phonetic IMEs can now query the input sequence of the Array and DaYi IMEs.
• The Array and DaYi IMEs can now query the input sequence of one another, in addition to the input sequence of the ChangJie, Quick, and Phonetic IMEs.
• The QuanPin, ShuangPin, and ZhengMa IMEs can now query the input sequence of one another.
• The Array, Dayi, QuanPin, ShuangPin, and ZhengMa IMEs now have options to disable the associate phrase.
• Multiple UI and behavior problems for the Array, Dayi, QuanPin, ShuangPin, and ZhengMa IMEs have been fixed.
• The ConIme.exe process no longer crashes when the Command Prompt window is wider than 160 characters.

When you connect a Bluetooth device to a computer that is running Windows Vista, no incoming request notification is displayed. This behavior occurs even though the Display notification of incoming request setting is enabled in the Bluetooth options.
