Symptoms

Assume that you are running a 32-bit application that has the /LARGEADDRESSAWARE option enabled on a computer that is running a 64-bit version of Windows. Then, the application calls various network-related APIs such as GetHostByAddress() or GetAdaptersAddresses(). In this situation, you may receive an error message that resembles one of the following:

  • WSANO_DATA

  • ERROR_NO_DATA (232)

  • ERROR_NOACCESS (998)

This issue occurs on 64-bit versions of the following operating systems:

  • Windows Vista

  • Windows Server 2008

  • Windows 7

  • Windows Server 2008 R2

Note This issue occurs if the application experiences high memory usage.

Cause

This issue occurs because of a problem with address-conversion routines. The 32-bit application passes a user-mode memory buffer that is allocated beyond the standard 2-gigabyte (GB) memory address space by using a network-related API such as GetHostByAddress() or GetHostByName(). The address is then converted from a 32-bit address to a 64-bit address in kernel routines. The address-conversion routines incorrectly sign-extend the particular address to convert it into a 64-bit address. This 64-bit address is outside the scope of the user-mode address pool. Therefore, the kernel denies read or write access to the address and returns an error to the application.

Resolution

After you install the hotfix, the conversion routines correctly convert a 32-bit address that is supplied by the user application to an equivalent 64-bit address without sign-extension.
