This article describes an issue that occurs after you apply April 2014 update rollup for Windows RT 8.1, Windows 8.1, and Windows Server 2012 R2 (2919355) on Windows Server 2012 R2. A hotfix is available to resolve this issue. The hotfix has a prerequisite.

Symptoms

When this issue occurs, the single tunnel throughput in the Routing and Remote Access Service (RRAS) gateway drops from 390 megabits per second (Mbps) to 220 Mbps. Therefore, every gateway can support only 30 site-to-site virtual private network (VPN) tunnels.

Resolution

To resolve this issue, we have released a hotfix. Even though this issue has been observed only in Windows Server 2012 R2, the hotfix also applies to Windows 8.1 and Windows RT 8.1.

Important Do not install a language pack after you install this hotfix. If you do, the language-specific changes in the hotfix will not be applied, and you will have to reinstall the hotfix. For more information, see Add language packs to Windows.

Windows 8.1 and Windows Server 2012 R2 file information and notes

Important Windows 8.1 hotfixes and Windows Server 2012 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 8.1/Windows Server 2012 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 files that apply to a specific product, milestone (RTM, SPn), and service branch (LDR, GDR) can be identified by examining the file version numbers as shown in the following table:

    Version

    Product

    Milestone

    Service branch

    6.3.960 0.17xxx

    Windows RT 8.1, Windows 8.1, and Windows Server 2012 R2

    RTM

    GDR

  • The MANIFEST files (.manifest) and the MUM files (.mum) that are installed for each environment are listed separately in the "Additional file information" section. MUM, MANIFEST, and the associated security catalog (.cat) files, are very 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.
