Symptoms

Consider the following scenario:

  • You deploy DirectAccess on a computer that is running Windows Server 2012 in a network environment. The environment contains some intranet resources that only have IPv4 addresses.

  • You enable external load balancing in the environment.

  • A DirectAccess client connects from the Internet to internal resources that only have IPv4 addresses.

In this scenario, DNS64 does not resolve the computer names of the internal resources. Therefore, clients cannot connect to the internal resources.

Cause

This issue occurs because the firewall does not enumerate loopback addresses and treats them as unknown addresses.

Windows Server 2012 file information notes

Important Windows 8 and Windows Server 2012 updates are included in the same packages.

  • 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

    6.2.920 0.16 xxx

    Windows Server 2012

    RTM

    GDR

    6.2.920 0.20 xxx

    Windows Server 2012

    RTM

    LDR

  • 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) that are installed for each environment are listed separately in the "Additional file information for Windows Server 2012" section. 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.
