Symptoms

You run an application that connects remotely by using a TCP connection on a computer that's running Windows 8, Windows 8.1, Windows Server 2012, or Windows Server 2012 R2. If the TCP connection uses ephemeral (short-lived) loopback addresses, the connection may be dropped suddenly after 40 to 50 seconds. However, the TCP connection is still "live" from the client side. In this situation, the application does not maintain the remote connection.

File information

The English (United States) version of this hotfix installs files that have the attributes that are listed in the following tables. The dates and the times for these files are listed in Coordinated Universal Time (UTC). The dates and the times for these files on your local computer are displayed in your local time together with your current daylight saving time (DST) bias. Additionally, the dates and the times may change when you perform certain operations on the files.

Important Windows 8 and Windows Server 2012 hotfixes are included in the same packages. However, only "Windows 8" is listed on the Hotfix Request page.
