Symptoms

Consider the following scenario:

  • You create a virtual private network (VPN) connection to an intranet on a client computer that is running Windows 7 or Windows Server 2008 R2.

  • You create the VPN by using a Connection Manager Administration Kit (CMAK) profile.

  • The VPN connection is based on Point-to Point Tunneling Protocol (PPTP).

  • CMAK performs a post-connect action. Specifically, CMAK downloads a .txt file that contains the VPN destination server list from an HTTP address.

In this scenario, the download operation fails and you receive an error message that resembles the following:

WinHttpOpen: error 87 [ERROR_INVALID_PARAMETER]

When this issue occurs, the client computer does not receive an updated destination server list. Therefore, the client computer may try to connect to access points that no longer exist. This behavior causes the VPN service to become unavailable.

Resolution

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 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

    6.1.760
    1.17xxx

    Windows 7 and Windows Server 2008 R2

    SP1

    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 for Windows 7 and for Windows Server 2008 R2" section. MUM and MANIFEST files, and the associated security catalog (.cat) files, are critical to maintaining the state of the updated component. The security catalog files, for which the attributes are not listed, are signed with a Microsoft digital signature.
