Symptoms

Consider the following scenario:

  • You have a computer that is running Windows 7 or Windows Server 2008 R2.

  • A Transport Driver Interface (TDI) filter driver is installed on the computer. For example, a TDI filter driver is installed when you install McAfee VirusScan.

  • An application opens a TCP listening port to receive connections.

In this scenario, the application may receive the following error message:

WSAECONNRESET (10054) Connection reset by peer.
A existing connection was forcibly closed by the remote host.

This issue occurs because the TCP/IP driver does not close an incomplete TCP connection. Instead, the TCP/IP driver sends a notification that the TCP/IP driver is ready to receive data when the incomplete TCP connection is created. Therefore, the application receives an instance of the 10054 error that indicates that a connection is reset when the application receives data from the connection.

Resolution

To resolve this issue, install this hotfix.

Note This hotfix temporarily resolves this issue for application vendors before they migrate their implementation to Windows Filtering Platform (WFP). These application vendors use the TDI filter driver or the TDI extension driver (TDX) on a computer that is running Windows 7 or Windows Server 2008 R2.

Windows 7 and Windows Server 2008 R2 file information notes


Important Windows 7 hotfixes and Windows Server 2008 R2 hotfixes are included in the same packages. However, hotfixes on the Hotfix Request page are listed under both operating systems. To request the hotfix package that applies to one or both operating systems, select the hotfix that is listed under "Windows 7/Windows Server 2008 R2" on the page. Always refer to the "Applies To" section in articles to determine the actual operating system that each hotfix applies to.

  • The MANIFEST files (.manifest) and the MUM files (.mum) that are installed for each environment are listed separately in the "Additional file information for Windows Server 2008 R2 and for Windows 7" section. MUM and MANIFEST files, and the associated security catalog (.cat) files, are extremely important to maintain the state of the updated components. The security catalog files, for which the attributes are not listed, are signed with a Microsoft digital signature.
