This article describes an issue that occurs when you remove site-to-site VPN interfaces in Windows Server 2012 R2. A hotfix is available to resolve this issue. The hotfix has a prerequisite.

Symptoms

When you run the Remove-VpnS2SInterface command to remove existing site-to-site VPN tunnel interfaces on a VPN server, this operation randomly fails. When this issue occurs, new site-to site VPN interfaces cannot be created on a VPN client that is running Windows 8.1 or Windows Server 2012 R2.

Cause

This issue occurs because of a race condition between VPN interface removal and creation.

Resolution

To resolve this issue, install the update rollup or the hotfix on both the VPN client and server.

The update rollup fixes many other issues in addition to the issue that the hotfix fixes. We recommend that you use the update rollup. The update rollup is larger than the hotfix. Therefore, the update rollup takes longer to download.

Get the update rollup for Windows 8.1 or Windows Server 2012 R2To resolve this issue, install the update rollup that is dated November 2014.

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:

    Windows 8.1 and Windows Server 2012 R2

    RTM

    GDR

  • GDR service branches contain only those fixes that are widely released to address widespread, critical issues. LDR service branches contain hotfixes in addition to widely released fixes.

  • 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.
