No data is transferred to the request buffer through the named pipe when an application calls the "TransactNamedPipe" function in Windows Vista or in Windows Server 2008

You develop an application that calls the TransactNamedPipe function to request data from a remote server. You run the application on a client computer that is running Windows Vista to request lots of data from a remote server that is running Windows Vista.

When you do this, the TransactNamedPipe function returns a "success" status. However, no data is transferred to the request buffer through the named pipe.

Additionally, the application on the client computer stops responding for about two minutes when the application calls the CloseHandle function.

Note This problem also occurs in Windows Server 2008.

You may also experience the following scenario:
When you perform a search on a Microsoft Office SharePoint Server 2007 site hosted on Windows Server 2008 and select the "View by Modified Date" hyperlink, you receive the following error:
Additionally, you will recieve the following error in the Unified Logging System (ULS) log:

Product: Windows SharePoint Services Category: Web Parts EventID: 89a1 Message: Error while executing web part: Microsoft.Office.Server.Search.WebControls.SrhdcGenericException: Your search cannot be completed because of a service error. Try your search again or contact your administrator for more information. ---> System.Runtime.InteropServices.COMException (0x80070040): The specified network name is no longer available.

You may also see this error in the Windows Application log of the SharePoint web front end server:

Source: Office Server Search EventID: 10038 Level: Error Query machine '<ServerName>' has been taken out of rotation due to this error: The specified network name is no longer available. 0x80070040. It will be retried in 15 seconds. Component: b487ab74-acae-4e99-ac77-fae246ae2895

This problem occurs because of an error in Windows Vista. If you use the TransactNamedPipe function to request more than 8,000 bytes of data, Windows Vista does not transfer the data correctly.
This problem may also occur because of an error in Windows Server 2008. If you use the TransactNamedPipe function to request more than 8,000 bytes of data, Windows Server 2008 does not transfer the data correctly.
